Important Information 

Introduction 

This manual is for the home caregiver—the person who provides 

care for a patient monitored by the N-595 pulse oximeter in the 

home. As the home caregiver, it is important that you read this 

entire manual before you use the monitor. 

This manual contains important safety information and monitor 

instructions. If you do not understand any part of this information, 

ask the clinician to explain it to you. 

Definitions 

Clinician: 

In this manual, the term “clinician” means the trained health care 

professional who assists you with monitoring the patient and using 

the N-595 monitor in your home. This person can be the doctor or 

nurse who is treating the patient, or some other trained health care 

professional. 

Normal Monitoring 

Mode: 

Normal monitoring mode means that: 

• the monitor is turned on, 

• a sensor is connected to the monitor, via the DOC-10 Pulse 

Oximetry Cable, 

• the sensor is applied to the patient, 

• the patient’s %SpO2 (oxygen saturation percentage) and pulse 

rate readings (BPM) are being reported, and 

• no error conditions exist. 

Home Use Guide 1

Important Information 

Oxygen 

Saturation: 

A measurement of the percentage of oxygen circulating in the 

patient’s blood. Oxygen saturation is also identified as %SpO2. 

Pulse Amplitude: 

The relative strength of the patient’s pulse. A higher pulse 

amplitude indicates a stronger pulse. A lower pulse amplitude 

indicates a weaker pulse. 

Pulse Oximeter: 

A medical device that measures a patient’s pulse rate and oxygen 

saturation in the blood. The N-595 monitor is a pulse oximeter. 

Pulse Rate: 

A measurement of the number of times the patient’s heart beats per 

minute. Pulse rate is also called beats per minute or BPM. 

Sensor: 

A sensor is an accessory used to collect and send patient 

information to the pulse oximeter monitor. One end of the sensor is 

attached to the patient’s finger, toe, ear lobe, or forehead and the 

other end of the sensor connects to the monitor cable. The sensor 

collects measurements by sensing the patient’s pulse rate and 

percentage of oxygen in the blood, and sends this information to the 

monitor. 

If You Need Help 

Contact the clinician if you have any questions or concerns about 

using the N-595 monitor. If you believe the monitor is not 

functioning properly, always notify the clinician, who may be able 

to correct the problem. 

If you require assistance in operating the equipment, and are unable 

to contact the clinician, call the 24-hour hotline of your medical 

equipment dealer. Keep the dealer’s business card with this manual. 

That card shows the hotline number.

Using the Monitor 

Introduction 

This chapter contains the instructions for the routine operation of 

the N-595 monitor in a home-use environment. If you have any 

questions, or are unsure how to proceed, always contact the 

clinician for clarification. 

Note: Many instructions indicate that the monitor should be in the 

“normal monitoring mode.” Normal monitoring mode means that: 

• the monitor is turned on, 

• a sensor is connected to the monitor, via the DOC-10 Pulse 

Oximetry Cable, 

• the sensor is applied to the patient, 

• the patient’s %SpO2 (oxygen saturation percentage) and pulse 

rate readings (BPM) are being reported, and 

• no error conditions exist. 

Factory Default Settings 

Unless otherwise instructed by the clinician, you will use the preset 

factory default settings for the N-595 parameters. The clinician may 

override the factory default settings with patient-specific settings. 

Check with the clinician for more information. 

The table below lists each parameter, its range in value or setting, 

and the factory default setting. The parameters may be set on an 

individual basis, as instructed by the clinician, and these altered 

settings remain in effect until the N-595 is turned off. If you turn off 

your monitor, you must reenter the values provided by the clinician 

when the monitor is turned on again. 



Caution: Each time the monitor is used, check the alarm limits 

to ensure that they are appropriate for the patient you are 

monitoring.

Turning On the Monitor 

Before using the N-595 to monitor the patient, verify that the 

monitor is working properly and is safe to use. Each time the 

monitor is turned on, it conducts a series of internal checks to verify 

proper operation, as described in the following section. 

Caution: If any indicator or display element does not light 

when the monitor is turned on, do not use the monitor. Instead, 

contact the clinician to report the problem. 

Caution: If the monitor speaker does not sound a one-second 

tone shortly after the power comes on, do not use the monitor. 

Instead, contact the clinician to report the problem. 

1. Turn on the N-595 by pressing the POWER ON/OFF button. 

2. Ensure that all of the front panel indicators illuminate. 



3. Once the display test portion of power-on sequence is complete, 

the N-595 software version is displayed for approximately five 

seconds. 

4. If the N-595 detects an internal problem during the internal 

check, an alarm tone sounds and the monitor displays the letters 

“EEE” followed by an error code number, similar to the 

example below. If an error code is displayed, contact the 

clinician immediately to report that the monitor is 

malfunctioning. 

5. Upon successful completion of the internal check, the N-595 

sounds a one-second tone indicating that the monitor has passed 

the test. 

Caution: If you do not hear the one-second POST pass tone, do 

not use the monitor. Instead, contact the clinician to report the 

problem. 

Caution: Do not place objects in front of the monitor’s speaker. 

Doing so could prevent you from hearing an audible alarm 

while monitoring the patient. 

30 N-595


Following successful completion of the self test, the monitor will 

immediately move into the patient monitoring mode. If there is no 

sensor connected to the monitor, or if the connected sensor is not 

applied to the patient, the monitor will not display readings for 

%SpO2 or pulse rate. 

If you have a sensor connected to the monitor and properly applied 

to the patient before the completion of the internal check, the 

monitor will begin searching for the pulse. Upon successfully 

detecting a pulse, the monitor will begin displaying the %SpO2 and 

pulse rate. 

Connecting a Sensor to the Monitor 

A Nellcor pulse oximetry cable, model DOC-10, must always be 

used to connect a sensor to the monitor. Refer to the directions for 

use accompanying the DOC-10 cable for additional information. 

Connect the DOC-10 cable to the monitor and plug the sensor into 

the DOC-10 cable, as instructed below. 

1. Connect the DOC-10 pulse oximetry cable to the oximetry 

sensor port located on the front panel of the monitor. 

2. Open the plastic latch at the opposite end of the cable and, with 

NELLCOR facing up on the sensor connector, plug the sensor 

and the DOC-10 cable together. Snap the plastic latch down 

over the connectors. 



The monitor briefly displays the model name of the sensor. 

Figure 9: Connecting Sensor and DOC-10 Cable 

3. Apply the sensor to the patient, as instructed by the clinician. 

Be sure to also read the directions for use accompanying the 

sensor. 

4. The N-595 searches for a valid pulse, indicated by the lighted 

pulse search indicator. 

5. When a valid pulse is detected, the monitor enters the 

monitoring mode and displays the patient readings (%SpO2 and 

pulse rate). 

6. Look for movement of the blip bar or the pleth waveform as an 

indication that the monitor is displaying real-time data. Listen 

for the pulse beep tone. 

32 N-595


If the pulse tone does not sound with each pulse, it is an 

indication that the pulse beep volume is set to zero, or that the 

speaker is malfunctioning, or that the pulse signal is corrupted. 

See Setting the Pulse Beep Volume on page 34. 

Note: If the sensor is not applied to the patient, or it is improperly 

applied to the patient, the monitor may display the following 

message. 

Selecting the BLIP View 

The BLIP view displays %SpO2, pulse rate, blip bar, and alarm 

limits in a larger format for easier viewing. It is better suited for 

viewing patient data in the home environment than the factory 

default PLETH view. (See Description of BLIP Display Information 

on page 13 for further details regarding the blip display.) 

With the monitor in the normal monitoring mode: 

1. Press the SETUP softkey. 

2. Press the VIEW softkey. 



3. Press the BLIP softkey. 

Setting the Pulse Beep Volume 

After the monitor begins reporting valid %SpO2 and pulse rate 

readings, you may adjust the pulse beep volume up or down. 

Press and hold the ADJUST UP or ADJUST DOWN button to 

increase or to decrease pulse beep volume. 

Setting the Alarm Volume 

If the volume of the audible alarm function is too soft or too loud, 

contact the clinician for assistance.

6. Use the ADJUST UP or ADJUST DOWN buttons to change the 

selected value. 

7. Press the EXIT softkey. 

Adult-Pediatric and Neonatal Settings 

The factory default patient monitoring mode is ADULT- 

PEDIATRIC, which uses upper and lower alarm limits for oxygen 

saturation and pulse rate that are typically appropriate for adult and 

pediatric patients. If you are monitoring a neonate or infant, you 

can change to the neonatal monitoring mode by pressing the 

LIMITS softkey and selecting NEO. The upper and lower limits for 

monitoring a neonate or infant differ from those for an adult or a 

pediatric patient. 

If you modify the default value(s) of alarm limits in either the adult 

or neonate monitoring mode, the change will remain in effect only 

until the monitor is turned off. You will need to reenter your limit 

changes each time you turn on the monitor. 

Caution: Each time the monitor is used, check the alarm limits 

and the monitoring mode to ensure that they are appropriate 

for the patient you are monitoring. 

The clinician will advise you as to whether or not you should use 

alarm limits other than the default values when monitoring the 

patient. If needed, the clinician can program the monitor to override 

the default limits, using instead the settings appropriate for the 

36 N-595


patient’s needs. You can discuss this option with the clinician. Refer 

to Table 3 for the adult/pediatric and neonate factory default limit 

settings.

or 

2. Press the ADULT or NEO softkey to select ADULT/PEDIATRIC 

limits or NEONATE/INFANT limits, respectively, based on the 

patient type you are monitoring. 

If the NEO mode is selected, NEO will appear in the lower right 

of the display and will be visible at the patient monitoring 

screen. 

3. Press the SELECT softkey as needed to select the parameter to 

be adjusted. 



4. Use the ADJUST UP or ADJUST DOWN button to increase or 

decrease the selected limit settings. 

5. Repeat steps 3 and 4 as necessary to complete the ALARM 

LIMITS setup. 

6. To accept the changes, let the display time out or press the EXIT 

softkey to exit the display and return to normal monitoring. 

Note: Remember that if you require the NEONATE/INFANT 

monitoring mode for the patient, you must reselect this 

mode each time you power on the monitor. Otherwise, 

the default monitoring mode (ADULT/PEDIATRIC) will 

be in effect. The clinician can change the power-on 

default to NEONATE if required. 

Setting Alarm Limits 

The ALARM LIMIT display allows you to adjust the upper and lower 

saturation and pulse rate limits. 

The ALARM LIMIT display includes the alarm limit table and the 

current measured %SpO2 and pulse rate. The title of the alarm limit 

table indicates whether the instrument is in ADULT or NEONATE 

monitoring mode. A decimal point after the displayed %SpO2 or 

pulse rate values indicate that the respective alarm limits have been 

changed from the power-on defaults. 


1. Press the LIMITS softkey. The alarm limits for the current 

monitoring mode are displayed.

5. Repeat steps 3, 4, and 5 as necessary to complete the alarm 

limits setup. 

6. To accept the changes, let the display time out or press the EXIT 

softkey to exit the display and return to normal monitoring. 

Note: Limit changes, as well as the selection of the NEONATAL 

monitoring mode, will only be in effect as long as the 

monitor remains turned on. When you turn the monitor off 

and back on, the factory default limits will again be in effect. 

The clinician may set up the monitor to always use settings other 

than the factory default values, based on the needs of the patient. 

These alternate settings are referred to as “institutional settings” 

and if the clinician programs them in the system, the monitor will 

use these as the power-up parameters in place of the factory default 

parameter values. 



Alarm Limit Changed Indicator 

Alarm limits that have been changed from the factory default 

settings are identified by a decimal point after the displayed reading 

(%SPO2 or BPM). The changed parameter is also identified by a 

decimal point on the alarm limits screen. 

Sensor Messages 

The N-595 monitor suggests possible solutions for sensor 

placement when the monitor is unable to report the patient’s oxygen 

saturation. The monitor will display sensor messages, based on the 

type of sensor in use, that suggest actions to resolve the problem. 

You can enable or disable the sensor messages feature. The default 

for this feature is “enabled.” 

Condition messages are followed by action messages. For example, 

up to three condition messages may be displayed in priority order, 

with the highest priority displayed on top. 

Remove the condition display by pressing the EXIT softkey. Once 

exited, the condition display will not return until a new condition 

occurs. 

40 N-595


If you press the HELP softkey from the condition message display, 

the action messages for the reported condition(s) are displayed. Up 

to five action messages may be displayed. Press NEXT, BACK, and 

EXIT softkeys to navigate through multiple screens that may be 

required to display all of the action messages. 

Sensor Message Setup 

Use this procedure to enable or disable the advanced sensor 

message feature. If you disable this feature, neither POOR SIGNAL 

CONDITION nor SUGGESTED ACTION will be displayed. 


Press the SETUP softkey.

eight languages. The languages available are ENGLISH, 

FRANCAIS (French), DEUTSCH (German), ITALIANO (Italian), 

ESPANOL (Spanish), NEDERLANDS (Dutch), PORT (Portuguese) 

and SVERIGE (Swedish). Consult with the clinician before 

attempting to change the displayed language. 

Note: When you turn the monitor off and back on, the factory 

default language, English, will again be in use. The clinician 

can program the monitor for a different default language, if 

appropriate. 



2. Press the NEXT softkey. 

3. Press the LANG softkey. 

42 N-595


Use the ADJUST UP or ADJUST DOWN buttons to select the 

desired language. 


Patient Trend Data 

The N-595 stores patient pulse and %SpO2 readings in memory, 

creating a patient trend data history that can be reviewed at any 

time by the clinician. The data are reviewed using the N-595 

software. 

Caution: Contact your clinician before throwing away a used 

disposable sensor as patient data is recorded by some sensor 

models. 

If it is necessary for you to access the patient data stored in the 

monitor, or the event data stored in the sensor, the clinician will 

provide instructions for accessing and viewing this data. 

Nurse Call Feature 

The N-595 has a feature called NURSE CALL. This feature is 

designed to assist qualified personnel in hospitals or similar health 

care centers. The nurse call mode, shown as NCALL, is an option 

accessed in the SETUP menu. This will not function in the home 

use environment. If you should enter the nurse call setup mode by 

accident, simply press the EXIT softkey to return to the main 

SETUP menu.

Prompt and Error Messages 

Introduction 

Prompt and error messages are displayed in the area normally 

reserved for softkey labels. Prompt messages prompt you for a 

response, while error messages provide information to you. The 

figures below provide an example of a prompt and an error message 

respectively. 

Managing Prompt and Error Messages 

Use Table 4 and Table 5 to determine what causes a specific 

message to be displayed, and how you can clear it. In these tables, 

the time-out value is the maximum time that the particular message 

will remain on the display. If the time-out is “None,” the message 

will remain on the display until you change the condition, by 

responding to the prompt (prompt message), by resolving the error 

condition (error message), or by pressing the ALARM SILENCE key 

(prompt or error message). 

Messages are prioritized so that more important messages will 

overwrite lower priority messages. Messages of the same priority 



will be displayed in order of occurrence. For multiple messages, 

lower priority messages will be displayed when higher priority 

conditions are cleared.

help. 

Caution: Use only Nellcor-approved OxiMax oximetry sensors 

and pulse oximetry cables. 

One or more of the following environmental factors or patient 

conditions can cause inaccurate measurements: 

• incorrect application of the sensor 

• placement of the sensor on an extremity with a blood pressure 

cuff, arterial catheter, or intravascular line 

• ambient light, such as a lamp at the patient’s bedside 

• prolonged and/or excessive patient movement 

• intravascular dyes or externally applied coloring, such as nail 

polish or pigmented cream 

• failure to cover the sensor site with opaque material in high 

ambient light conditions 

One or more of the following environmental factors or patient 

conditions can cause loss-of-pulse signal: 

• sensor is too tightly wrapped around the patient’s digit or other 

extremity 

• an inflated blood pressure cuff on the same extremity as the one 

with the sensor attached 

• an arterial occlusion (blocked artery) proximal to the sensor 

• poor peripheral profusion (circulation) 

50 N-595


If patient movement presents a problem, under the guidance of the 

clinician, you may try one or more of the following remedies to 

correct the problem: 

• verify that the sensor is properly and securely applied 

• move the sensor to a less active site 

• use an adhesive sensor that tolerates some patient motion 

• use a new sensor with fresh adhesive backing 


(Blank Page)

Battery Operation 

Operating on Battery Power 

The N-595 monitor has an internal battery that may be used to 

power the monitor during transport or when AC power is not 

available. A new, fully charged battery will provide at least 2 hours 

of monitoring time under the following conditions: 

• no audible alarms sound 

• no analog or serial output devices are attached to the N-595 

The monitor cannot operate with a fully discharged battery. Before 

attempting to turn on an N-595 monitor whose battery charge has 

been completely depleted, first plug the monitor into an electrical 

outlet (AC power) and allow the battery to charge for a few 

minutes. When the battery achieves a nominal charge, the monitor 

may then be powered on and operated using AC power only. 

Automatic Shutdown to Conserve Battery 

If you operate the monitor using the battery, the monitor will 

automatically shut down to conserve the battery when all of the 

three following conditions are present for 15 minutes: 

• no buttons have been pressed 

• no pulse has been detected (for example, no patient is connected 

to the sensor or the sensor is disconnected from the monitor) 

• no alarms are present (other than low battery or a noncorrectable 

error) 



Caution: Do not use the N-595 monitor with battery power 

unless instructed to do so by the clinician. It is recommended 

that the N-595 monitor remain plugged into an AC power 

outlet. 

Note: Whenever the monitor is connected to AC power, the battery 

is being charged. Therefore, it is recommended that the 

monitor remain connected to AC power when not in use. 

This will ensure a fully charged battery whenever it is 

needed. 

Recharging the Battery 

To charge a low or dead battery, connect the monitor to an electrical 

outlet (AC power). Fourteen hours of charging are required to fully 

charge a dead battery if the monitor remains off. A full charge of a 

dead battery takes 18 hours if the monitor is in operation 

(monitoring a patient). 

As the battery is used and recharged over a period of time, the 

amount of time between the onset of the low battery alarm and the 

instrument shut-off may become shorter. 

Low Battery Indicator 

The LOW BATTERY indicator lights and a low priority alarm 

begins to sound when approximately 15 minutes of monitoring time 

are available on the existing battery charge. 

If the monitor is not on AC power, a low battery audible alarm can 

be canceled by pressing the ALARM SILENCE button. The low 

battery indicator and display screen message will continue to be 

displayed. Press the ALARM SILENCE button a second time to 

clear the message from the display. Plugging the monitor into AC 

power will silence the audible alarm, but the low battery indicator 

will stay lit as long as the battery is in the low voltage condition. 

After the 15-minute period of low battery condition, a high priority 

alarm will sound for about 10 seconds before the monitor shuts off. 

54 N-595


If the monitor backlight is turned off during a low battery condition, 

the backlight cannot be turned back on. 

Caution: If the N-595 monitor is to be stored for a period of two 

months or longer, contact the clinician for storage instructions. 

Recharge the battery when the battery has not been charged 

for two or more months. 

Note: If the AC voltage selector switch on the monitor rear panel 

does not match your AC voltage source, the monitor may run 

on battery power, even though it is plugged into AC power. 

This situation will eventually result in a low priority alarm 

and a lighted low battery indicator. Ensure that the switch 

setting matches your AC voltage (115V). 

Note: As the battery is used and recharged over a period of time, 

the amount of time between the onset of the low battery 

alarm and instrument shut-off may become shorter.

Troubleshooting 

WARNING: The cover should be removed only by qualified 

service personnel. There are no user-serviceable parts inside. 

Caution: Do not spray, pour, or spill any liquid on the N-595, its 

accessories, connectors, switches, or openings in the covers. 

Error Codes 

When the N-595 detects an error condition, it may display three 

letters, “EEE”, followed by an error code. 

When an error code is displayed, turn the instrument off and back 

on again. If the error code reappears, record it and notify the 

clinician immediately. You may also choose to contact your 

medical equipment dealer. 

Solving Problems 

Following is a list of possible problems and suggestions for 

correcting them. If you cannot correct a problem, immediately 

contact the clinician for further instructions. Do not attempt to 

monitor the patient using a monitor that fails the power-on test or is 

otherwise not operating properly. 



1. There is no response to the POWER ON/OFF button. 

• Ensure that the supply voltage selector switch is set to the 

proper voltage (115V). 

• Verify that the wall outlet you are using to power the monitor 

is functioning. 

• If you are operating on battery power, check for a lighted 

LOW BATTERY indicator. If the LOW BATTERY indicator is 

lit, this indicates that the battery is discharged. To recharge 

the battery, see Recharging the Battery on page 54. 

• A fuse in the monitor may be blown. Notify the clinician. 

2. One or more display segments or front panel indicators do not 

light during the power-on self-test. 

• Do not use the N-595. Contact the clinician for further 

instructions. 

3. The PULSE SEARCH indicator is lit for more than 10 seconds 

after you begin monitoring the patient. (No readings are 

reported.) 

• Check the sensor site. The sensor may be applied too tightly 

to the patient’s digit. Reapply the sensor, as necessary. 

• The sensor may be on an extremity with a blood pressure 

cuff, an arterial catheter, or intravascular (I.V.) line. Contact 

the clinician for further guidance. 

• Excessive ambient light, such as a bedside lamp or direct 

sunlight, may interfere with measurements. Cover the site 

with an opaque blanket or towel. 

• Excessive patient motion may be preventing the N-595 from 

tracking the pulse. Keep the patient still, if possible. Verify 

that the sensor is securely applied, and replace it if necessary. 

Note: If patient motion is an ongoing issue, contact the 

clinician, who may be able to suggest the use of an 

alternate sensor site or a different sensor model. 

58 N-595


• Contact the clinician to ensure you are using a sensor model 

appropriate for the patient you are monitoring. 

• Excessive electromagnetic interference may be preventing 

the N-595 from tracking the pulse. Remove the source of the 

interference. See EMI (Electromagnetic Interference) on 

page 60 for more information. 

4. The PULSE SEARCH indicator lights after some patient 

readings have been reported. 

• Check the patient. 

• Check the sensor site. The sensor may be applied too tightly 

to the patient’s digit. Reapply the sensor, as necessary. 

• The sensor may be on an extremity with a blood pressure 

cuff, an arterial catheter, or intravascular (I.V.) line. Contact 

the clinician for further guidance. 

• Excessive patient motion may be preventing the N-595 from 

tracking the pulse. Keep the patient still, if possible. Verify 

that the sensor is securely applied, and replace it if necessary. 

Note: If patient motion is an ongoing issue, contact the 

clinician, who may be able to suggest the use of an 

alternate sensor site or a different sensor model. 

• Contact the clinician to ensure you are using a sensor 

appropriate for the patient you are monitoring. 

5. The monitor displays three letters, “EEE”, followed by a 

number. 

• This is an error code. To confirm, turn the monitor off and 

back on again. If the error code occurs again, record the 

number and provide that information the clinician or your 


6. LOW BATTERY message is displayed. 

• LOW BATTERY is displayed when the battery is discharged 

to a critically low level. Check to ensure that the voltage 



selector switch on the rear panel is set to 115V. Recharge the 

battery. (See Recharging the Battery on page 54.) 

• If you have recharged the battery for about ten minutes after 

a LOW BATTERY message was reported, turn on the 

monitor. If the same error message is still present, turn the 

monitor off and allow it continue recharging for another 

twenty minutes. Check for the error message again by 

turning on the monitor. If the error condition persists, notify 

the clinician immediately. Do not use the monitor on the 

patient. 

EMI (Electromagnetic Interference) 

Caution: This device has been tested and found to comply with 

the established limits for medical devices. These limits are 

designed to provide reasonable protection against harmful 

interference in a typical home-use environment. 

Because of the proliferation of radio-frequency transmitting 

equipment and other sources of electrical noise in the home-use 

environment (for example, cellular phones, mobile two-way radios, 

electrical appliances, and high-definition television), it is possible 

that high levels of such interference, due to proximity or strength of 

a source, may result in disruption of performance of this device. 

Disruption by EMI may be evidenced by erratic readings, cessation 

of operation, or other incorrect functioning of your monitor. If this 

occurs, the area around the monitor should be surveyed to 

determine the source of this disruption, and the following actions 

taken to eliminate the source: 

• Turn off the equipment off and on in the vicinity of the monitor 

to isolate the offending equipment. 

• Reorient or relocate the interfering equipment. 

• Increase the separation between the interfering equipment and 

the N-595 monitor. 

60 N-595


The N-595 generates, uses, and can radiate radio frequency energy 

and, if not installed and used in accordance with the instructions in 

this manual, may cause interference with other devices in the 

vicinity. 

If assistance is required, contact the clinician.

Maintenance 

Service 

WARNING: Do not remove the cover on the monitor. You may 

cause the instrument malfunction and/or void any warranty. 

The N-595 requires no routine service or calibration other than 

changing the battery at least every 24 months. (The clinician will 

provide assistance if the battery requires replacement.) 

If service is necessary, inform the clinician, and contact your 


Periodic Safety Checks 

It is recommended that the following checks be performed every 

24 months. 

• Inspect the equipment for mechanical and functional damage. 

• Inspect the safety-related labels for legibility. 

Cleaning 

Caution: Do not spray, pour, or spill any liquid on the N-595, its 

accessories, connectors, switches, or openings in the chassis. 

For surface-cleaning and disinfecting the monitor, follow the 

clinician’s instructions or: 

• The N-595 may be surface-cleaned by using a soft cloth 

dampened with either a commercial, nonabrasive cleaner or a 

solution of 70% alcohol in water, and lightly wiping the surfaces 

of the monitor. 


Maintenance 

• The N-595 may be disinfected using a soft cloth saturated with a 

10% chlorine bleach solution, diluted in tap water. 

Before you clean an oximetry sensor, check the directions for use 

enclosed with the sensor for applicable cleaning instructions. If no 

cleaning instructions are present, the sensor is a disposable sensor 

and should be replaced rather than cleaned. 

The pulse oximetry cable may be surface-cleaned. Refer to the 

directions for use, enclosed with the cable, for applicable cleaning 

instructions.
