Controls and Settings
Adjustable Airway Pressure Relief (continued)
•
When the delivered airway pressure is greater than the adjustable airway pressure
setting, the pressure relief will be activated and an audible squeak will be emitted
from the airway pressure relief valve.
•
The initial setting for this control is typically at the 60 cm mark on the face. Note
that this will not necessarily yield a 60cm H
2
O pressure. The 60 mark indicates that
the valve will open to prevent airway pressures exceeding 60cm H
2
O. Under normal
ventilation parameters, the actual airway pressure is well below this setting.
•
To set the airway pressure relief, attach the circuit to the vent and occlude the end
of the circuit with the palm of your hand. Note the maximum airway pressure.
Adjust the knob downwards from 60 cm until you reach the desired maximum
airway pressure as indicated by the peak airway pressure readout on the LCD.
