13) Verify the power failure (power failure alarm)
Set the IPPV+ASS. operative mode.
Disconnect the electric main power supply.
Verify that:
- the ON LINE led switches-off and the ON-BAT led switches-on flashing
- an acoustic alarm occurs
- the alarm is resettable by pressing the alarm reset button
- the ventilator keep on working
- the Rate, Minute volume display and airways pressure led bar are always on
- every 10 seconds are displayed also all other setted parameters.

14) Verify the bronchomanometer
Connect the patient circuit by a T connector to the patient simulator and to the P+ inlet of RT200 setted with
program 12 and with PEAK option.
Set the following parameters:
- operative modality = IPPV
- Flow = 10 L/min ( to check the PEEP at 20 ) – 5 L/min (to check the PEEP at 10 );
- Rate = 20;
Act on PEEP knob so to set on Max/Mean airway pressure display the following pressures and verify that
the displayed values on RT200 are within the corresponding acceptance limits.

15) Verify leakage absence
15a) Tightness test from valves group to patient (Low pressure circuit leakage)
Connect the patient circuit to patient simulator.
Set the following parameters:
- Operative modality = SPONT SIMV;
Act on PEEP knob so to set on airway pressure bar led the pressure of 20 cm H 2 O.
Verify that on the airway pressure bar led and on patient simulator manometer is displayed the pressure of
O ± 2 cmH
20 cmH

15b) Tightens Test of circuit (Leakage on main circuit)
Switch-off the ventilator.
Close upstream the manometer on the couple gas supply.
Verify that the pressure on manometer does not decrease under 3 bar in 30 sec.
