⇒ The full recharge procedure first empties the battery of
all its charge. Charging it to capacity then allows for
proper calibration of the battery gauge.
To perform a full recharge procedure:
1. Plug the AC power cord into the ventilator.
Verify that the amber “charge” LED is lit.
2. Allow the unit to charge for at least 10 hours.
3. Switch on the ventilator. When the opening
window appears, select the 70kg patient
weight setting.
4. Set the pressure alarm to 60 (cmH
2
0).
5. Connect the ventilator with a patient circuit to
the Rp20 resistor and test lung.
6. Press “START” on the ventilator. (See Section
3.1.1, page 63 for directions on starting the
iVent
201
.)
7. Adjust the tidal volume (Vt) so that a PIP
(peak inspiratory pressure) of 40 is attained on
each breath – for example, a value of 850.
8. Disconnect the power cord. The battery alarm
will sound and a pop-up window will appear.
Press the red Silence button on the keypad to
remove the pop-up window and stop the
alarm.
9. Now allow the ventilator to run off the battery
continuously. When the Empty Battery alarm
sounds, clear it by pressing the red Silence
button on the keypad.
