SPONT (Spontaneous Ventilation) ▲ Up and ▼ Down Control SECTION 3 In this mode, all breaths are patient triggered by spontaneous efforts. Psupport (Pressure Support Ventilation) may be used to support spontaneous efforts. When PEEP/CPAP is set above 0, the ventilator mode is CPAP (without Psupport) or Bilevel Positive Airway Pressure (with Psupport). The ▲Up/▼Down control buttons have multiple uses on the HT50. 1. Parameter Adjustment: Use the ▲Up/▼Down buttons to adjust ventilation control parameter values (including Pressure Control and Volume Control values), alarms, and humidifier setting (if available). Select the desired parameter by pressing its touch button once. The corresponding value (numerical display) will blink. Press the ▲Up control to increase or the ▼Down to decrease the affected parameter value. The value continuously changes when the ▲Up/▼Down controls are pressed and held. The value adjustment is accepted if (1) the user presses the selected parameter button again, or (2) the user selects a different parameter, or (3) five seconds elapses. Pressing a parameter button without pressing either the ▲Up or ▼Down control button within 5 seconds causes the parameter to retain its current value. NOTE: If in the On condition and switching between Volume Control and Pressure Control, the value adjustment for the new breath type selected (Volume or Pressure) will be accepted as noted above, but the breath type (VC or PC) will only change if the user presses the new breath type control button again. 2. Monitored Information: The ▲Up/▼Down controls are used to access and display monitoring messages in the Message Display Window. Monitored information includes volume, frequency, pressure values and operation information. See pg 3- 23 for more information on the Message Display Window. When the HT50 is ventilating, and there are no alarm messages displayed on the Message Display Window, press the ▲Up control button to access the monitoring information. Pressing the ▲Up button again allows you to scroll through the messages. 3. Changing Default Settings: The ▲Up/▼Down controls are also used in User Set Up to change a set up value. See User Set Up on pg 3-27 for more details. OPRHT50NA B0908 3-7
DESCRIPTION OF CONTROLS, INDICATORS, ALARMS & CONNECTIONS ƒ (frequency) t I (inspiratory time) Volume Control (tidal volume) Range: 1 to 99 b/min The ƒ (frequency) setting determines the minimum number of time triggered mandatory breaths in the A/CMV mode and the total number of mandatory breaths in the SIMV mode. The frequency or rate value is displayed in the window adjacent to the selector button. The user is alerted to frequency settings which result in an inverse I:E Ratio by an audible beep and an “Inverse I:E” message in the Message Display Window. Attempts to continue increasing the value after this alert are permitted up to an I:E Ratio of 3:1. NOTE: In SPONT mode, the ƒ setting is not utilized but the value can be preset. Range: 0.1 to 3.0 sec The t I setting determines the inspiratory time for mandatory breaths (volume or pressure control). The selected time value is displayed in the window adjacent to the selector button. The user is alerted to t I settings which result in an inverse I:E Ratio by an audible beep and an “Inverse I:E” message in the Message Display Window. Attempts to continue increasing the value after this alert are permitted up to an I:E Ratio of 3:1. If the inspiratory time setting causes the flow rate to reach the maximum or minimum level of the flow specification, adjustment of t I ceases, a beep sounds, and a setting limitation message appears in the Message Display Window. NOTE: In SPONT mode, the t I setting is not utilized but the value can be preset. NOTE: See pg. 3-24 for a list of setting limitation messages. Range: 100 to 2,200 mL, ATPS NOTE: When Volume Control is first initiated, or when a large change is made to the volume setting, it may take 5 or 6 breaths to reach the volume setting. Pressing this control button, followed by pressing the ▲Up/▼Down controls, allows the adjustment of the tidal volume setting. When the green Volume Control LED illuminates, the adjacent window displays the set tidal volume. See Theory of Operation, pg 4-5 for more details. 3-8 OPRHT50NA B0908
