As we know, the oxygen tubes are used for transport ventilators.

Underhere are some detection methods of air leakage in oxygen supply tubes.

1. Turn off or disconnect the oxygen equipment, and turn on the pressure reducer switch of the oxygen cylinder;

2. Wait until the pressure gauge pointer rises to the highest point, and then close it to see if the pressure gauge pointer drops;

3. The pressure gauge pointer does not drop or drops very slowly, indicating no air leakage;

4. If the pressure gauge pointer drops quickly, there will be air leakage point;

5. Air leakage point inspection: apply soap water on each interface to see if there are bubbles;

6. This method is applicable to the air supply tubes of transport ventilator, oxygen inhaler and central oxygen supply in the ambulance;
