1.
Attach the appropriate interface to the patient.

The unit will cycle from inhale (positive) to exhale (negative) to zero pressure, and
back to inhale.
3.
After 4 to 5 cycles, set the manual/auto switch back to the manual position. Remove
the patient interface from the patient and allow time for a normal breathing pattern to
return (20 to 30 seconds), or place the patient back on the ventilator if currently in
use. Avoid prolonged periods connected to the device. During this resting period, clear
secretions that may have become visible in the mouth, throat or tracheostomy tube.

It is recommended that the CoughAssist MI-E be periodically tested to ensure that the
cycling valve returns to the neutral, or pause, position after either the inhale or exhale
phase. To determine this, follow these steps:
1.
Attach a patient circuit to the unit and block the end of the hose.
2.
Turn the power switch ON.
3.
Set the manual/auto switch to the manual position (automatic models only).
4.
Set the pressure knob fully clockwise (maximum pressure).
5.
Cycle the manual control lever from inhale to exhale and observe the pressure gauge
to ensure that positive and negative pressure is being applied to the patient circuit.
6.
Release the manual control lever from the inhale position and observe that the pressure
immediately drops to 0 cm H
pressure does not drop to zero, the unit should be returned for repair.
