Heliox is a mixture of helium and oxygen, and can be indicated
for patients in cases of acute and life-threatening upper airway
obstruction. This action is taken as a temporary measure to
provide a decrease in the patient’s work of breathing while the
cause of the obstruction is treated.
Administering heliox can make it easier to ventilate, because its
lower density can allow a patient to produce inspiratory and
expiratory flows with less turbulence.
To select the desired gas:
1. Put the ventilator in standby.
2. Open the
System -> Gas source window (Figure 4-6).
choose the
Air or Heliox button. Close the window.
3. Close the window.
The message
Flow Sensor Cal. needed is displayed.
4. Calibrate the flow sensor.
When heliox is selected, the alarm lamp on top of the cockpit
displays a blue color. If the ventilator alarms while heliox is
being delivered, the blue lamp alternates with red or yellow.
