TA80V User Manual
4.6.1. Check Oxygen Flush Supply Switch
Press the oxygen flush supply button, and there should be obvious air flow sound at the fresh gas
outlet. After releasing the button, the button can automatically rebound and stop air supply.
4.6.2. Check Air Tightness
Switch the working mode of the animal anesthesia machine to "manual", adjust the airway pressure
gauge to the "zero" position, turn the APL valve clockwise to the maximum scale position, connect the
three-way Y-shaped joint of the mask to the simulated lung, and connect the manual skin bag Put it
on the interface of the extension tube, press the rapid oxygen supply button or turn on the flow meter,
so that the indication of the airway pressure gauge reaches 3kPa, release the rapid oxygen supply
button, close the flow meter, and observe for 20 seconds, the airway pressure gauge indicates The
pressure drop value should not exceed 0.3kPa.
4.6.3. Test the APL Valve
Adjust the positions of switches and knobs according to the method of checking air tightness. Open
the oxygen flow to 5L/min, adjust the APL valve so that the airway pressure gauge pressure is stable
at different positions. When the airway pressure gauge pressure is stable, airflow should overflow
from the APL valve exhaust hole.
Warning
Make sure there are no test plugs or other foreign objects in the respiratory system.
4.7. Ventilator Test
