Alarms and Troubleshooting<br />
Table 3-2. Alarms and Corrective Actions (Continued)<br />
Alarm Message or<br />
Symptom Possible Reason(s) For The Alarm Event Corrective Action(s)<br />
HIGH VTI<br />
INSP FLOW<br />
RESTART/SRVC<br />
INTENTIONAL<br />
VENT STOP<br />
KEYPAD FAULT<br />
RESTART/SRVC<br />
LOW BATTERY<br />
LOW FIO 2<br />
Adjustment of the Max VTI level too low<br />
(for PSV, CPAP, P A/C, P SIMV and V SIMV<br />
modes).<br />
Adjustment of the pressure level too high<br />
for the volume required (for PSV, CPAP,<br />
P A/C, P SIMV and V SIMV modes).<br />
A leak in the patient circuit causing<br />
increased bias flow.<br />
Note:<br />
Always consult the clinician before<br />
changing PEEP, FIO 2 , pressure, volume or<br />
Rate settings.<br />
Modify the Max VTI level.<br />
Note:<br />
Always consult the clinician before<br />
changing PEEP, FIO 2 , pressure, volume or<br />
Rate settings.<br />
Modify the pressure level.<br />
Check and properly connect the patient<br />
circuit.<br />
Inappropriate patient circuit. Replace the patient circuit.<br />
Defective flow sensor or internal leak in the<br />
machine.<br />
Inspiratory flow is constant (± 1 lpm) with<br />
normal turbine temperature and speed<br />
conditions.<br />
The user / caregiver has stopped ventilation<br />
using the VENTILATION ON/OFF key.<br />
Ventilation is in stand-by.<br />
Pressing a key for more than 45 seconds.<br />
A key on the keyboard is stuck.<br />
Internal battery capacity is less than 30 min.<br />
(or 8%)—battery operation overextended.<br />
The level of oxygen being delivered to the<br />
patient is below the Min FIO 2 limit set.<br />
Have a qualified technician replace the<br />
defective component(s) and call your<br />
customer service representative.<br />
Restart ventilator to see if alarm clears. If<br />
not, replace the ventilator and call your<br />
customer service representative.<br />
Check that the ventilation was switched off<br />
on purpose.<br />
Press and release keys in the normal,<br />
prescribed manner. Do not press keys for 45<br />
seconds or more.<br />
If unsuccessful in releasing the stuck key(s),<br />
restart ventilator to see if alarm clears. If<br />
not, replace the device and call your<br />
customer service representative if the<br />
situation persists.<br />
Immediately connect the ventilator to an<br />
AC power outlet, or connect it to an<br />
external DC power source.<br />
Reminder: the internal battery can be<br />
charged only when the ventilator is<br />
connected to an AC power supply.<br />
Note:<br />
Always consult the clinician before<br />
changing PEEP, FIO 2, pressure, volume or<br />
Rate settings.<br />
Check the level of oxygen corresponds to<br />
the patient’s prescription or<br />
Decrease the FIO 2 alarm threshold.<br />
