Warning：
In case of any problem during inspection, stop using it for the patient!
1. Connect power supply and air supply, and check whether the power
supply and air supply operate normally.
2. Start the machine to make it perform self-checking, to mainly inspect
whether all sensors operate normally.
3. Perform an asphyxia alarm inspection in accordance with the following
steps:
a) Set asphyxia alarm time to 15s.
b) Set respiration mode to CPAP, and start timing; record the time elapsed
before asphyxia alarm is triggered, and compare it with the set value.
The tested time value should range between 13s and 17s.
4. Check alarm triggered by upper airway pressure limit in accordance with
the following steps:
a) Set the ventilator to V-A/C ventilation mode.
b) Set Vt to 600ml, I/E to 1: 2, and frequency to 10.
c) Set Pmax to 20cmH20.
d) Block with hand the connection port of Patient Breathing Valve to
generate an airway pressure higher than 20cmH20, and at this moment
audible and visual alarm should be triggered by the excessive airway
pressure. Release hand, and the alarm should be removed about 10
seconds later.
5. Perform an inspection on respiratory system integrity alarm function in
accordance with the following steps:
a) Set the ventilator to V-A/C ventilation mode.
b) Set Vt to 600ml, I/E to 1: 2, frequency to 10, and Pmaxto 30cmH20.
c) With Patient Breathing Valve not connected to model lung, audible and
visual alarm should be triggered by such disconnection after two
respiratory cycles; and the alarm should be removed after the model
lung is connected.
