Pressure Control (target pressure) SECTION 3 If the Volume Control setting causes the flow rate to reach the maximum or minimum level of the flow specification, adjustment of Volume Control ceases, a beep sounds, and a setting limitation message appears in the Message Display Window. NOTE: See pg. 3-24 for a list of setting limitation messages. NOTE: In SPONT mode, the Volume Control is not utilized but the value can be preset. Switching from Pressure Control to Volume Control: Press the Volume Control button. The set tidal volume is displayed in the adjacent window if the HT50 is ventilating. A “PRESS AGAIN” message appears in the Message Display Window. Adjust the tidal volume level by pressing the ▲Up/▼Down controls while the LED and numerical display are blinking. If the HT50 is ventilating you will need to press the Volume Control button again within 5 seconds following adjustment. Range: 5 to 60 cmH 2 O / mbar NOTE: When Pressure Control is first initiated or the setting is changed, the first few breaths may cycle off early until slope/rise is optimized. If early cycling off continues, re evaluate the breathing circuit configuration and lengthen the tubing as necessary. Pressing this control button, followed by pressing the ▲Up/▼Down controls, allows the adjustment of the target airway pressure setting. Target pressure is referenced to ambient (atmospheric pressure). When the green Pressure Control LED illuminates, the adjacent window displays the set airway pressure. See Theory of Operation pg 4-4 for more details. NOTE: In SPONT mode, the Pressure Control is not utilized but the value can be preset. Switching from Volume Control to Pressure Control: Press the Pressure Control button. The set target airway pressure value is displayed in the adjacent window if the HT50 is ventilating. A “PRESS AGAIN” message appears in the Message Display Window. Adjust the set target airway pressure by pressing the ▲Up/▼Down controls while the LED and numerical display are blinking. If the HT50 is ventilating you will need to press the Pressure Control button again within 5 seconds following adjustment. OPRHT50NA B0908 3-9
DESCRIPTION OF CONTROLS, INDICATORS, ALARMS & CONNECTIONS Ptrig (sensitivity) PEEP/CPAP Psupport (pressure support) NOTE: The minimum target airway pressure is 5 cmH 2 O / mbar above set baseline pressure. Range: 0.0 to –9.9 cmH 2 O/mbar The Ptrig setting determines trigger sensitivity in terms of how far airway pressure must drop below the set baseline pressure for a patient’s spontaneous efforts to be detected. The Ptrig LED indicator illuminates each time the airway pressure reaches the set Ptrig level, and turns off once the airway pressure has returned to baseline pressure. The blinking Ptrig LED is referred to as the Patient Effort Indicator. The Ptrig value is displayed in the adjacent window. Set Ptrig as close to 0.0 cmH 2 O as possible without autotriggering to maximize triggering synchrony. Range: 0 to 30 cmH 2 O/mbar The PEEP/CPAP setting establishes airway pressure in the patient circuit during the exhalation phase. It is also referred to as base or baseline pressure. The set PEEP/CPAP value is displayed in the adjacent window. NOTE: In Pressure Control ventilation, PEEP/CPAP cannot be set higher than 5 cmH2O/mbar below the set Pressure Control setting. NOTE: The value of PEEP/CPAP plus Psupport cannot exceed 60 cmH2O/mbar. Range: 0 to 60 cmH 2 O/mbar The Psupport (pressure support) setting determines the target rise/change in pressure during inspiration for patient triggered spontaneous breaths in SIMV and SPONT modes. The target pressure is the set Psupport plus the PEEP level. Any time the active Psupport control is pressed, Psupport flow delivery slows to a lower level then it gradually increases to the appropriate level as pressure rise is re-assessed. NOTE: The value of PEEP/CPAP plus Psupport cannot exceed 60 cmH 2 O/mbar. 3-10 OPRHT50NA B0908
