3.4.5 Life-Stat
®
Ventilator- Patient Demand Valve (PDV) Activation:
A.
Rotate the VENTILATION VOLUME knob (#3) clockwise in accordance with AHA
guidelines, and/or local protocol to desired volume (mL).
B.
Apply the Breathing Hose/Non Re-breathing Valve to the patient via mask or ET tube.
C.
The ventilator contains a Pressure Limit Alarm that will sound an audible alarm when the
airway pressure exceeds 55cm H
2
O. Monitor the patient airway to identify the cause for the
increased pressure and take the appropriate corrective action.
WARNING: During ventilation, the operator must maintain constant
attention to ensure the patient is properly ventilated.
WARNING: Excessive ventilation may be delivered to the patient if the
ventilation volume is set too high or the knob inadvertently moved
clockwise.
WARNING: Patient ventilation may be insufficient if the ventilation
volume is set too low or the knob inadvertently moved counterclockwise.
WARNING: Should the blue rubber diaphragm blow outward from the
Pressure Limit Alarm's relief ports, discontinue the use of the Life-Stat
®
ventilator. It is recommended to manually ventilate the patient until
such time that a spare replacement alarm can be installed.
CAUTION: If the maximum pressure limit is reached (the pressure limit
alarm sounds), the pre-set tidal volume may not be delivered to the
patient. No additional volume will be delivered until the next ventilation
cycle.
NOTE:
An audible Pressure Limit Alarm is attached to the PDV. This
alarm sounds whenever the patient airway pressure reaches the designed
release pressure limit of 55cm H
2
O. The Pressure Limit Alarm will continue
to sound during the inspiratory phase until either the airway pressure
decreases or the next ventilation cycle begins.
