Mindray WATO EX-65 - Check the Mechanical Ventilation Mode

4-10
3
Breathing
system leak
test in manual
ventilation
mode
Check the pneumatic circuit in manual ventilation mode
for leaks, including APL valve, check valve, sodalime
canister, patient tubes, flow sensors and their connectors.
After each
service or at
the time of
return visit
4
Check the
sensors’ zero
points
Check if the zero points of all the flow sensors and
pressure sensors inside the machine are within the normal
range so as to determine when to replace the monitor
board.
After each
service or at
the time of
return visit
5
Check the flow
sensor
accuracy
1. Check if the measurements made by the flow sensors
inside the machine are the same.
2. Check if the measurement made by any flow sensor
inside the machine is accurate.
3. Check the effectiveness of flow calibration (factory)
result.
After each
service or at
the time of
return visit
6
Check the
pressure sensor
accuracy
1. Check if the measurements made by the pressure
sensors inside the machine are the same.
2. Check if the measurement made by any pressure sensor
inside the machine is accurate.
3. Check the effectiveness of pressure calibration (factory)
result.
After each
service or at
the time of
return visit
7
Check the
electronic
flowmeter
accuracy
1. Check if the measurement made by the electronic
flowmeter is normal.
2. Check the effectiveness of electronic flowmeter
calibration result.
After each
service or at
the time of
return visit
4.2.1 Check the Mechanical Ventilation Mode
NOTE
z The main function of the anesthesia machine is to provide breathing
support—mechanical ventilation which complies with the doctor’s settings to the
patient. The tests in this section are performed aiming to ensure that the machine is
able to provide normal mechanical ventilation.
z The tests can help to judge if the machine operates normally.
