Usage and precautions of oxygen mask

1. Usage of medical oxygen mask

(1) Prepare the necessary items for the oxygen mask, carefully check the bed number and name, clean the face and wash hands before operation, wear a mask, and tidy personal clothes to prevent wearing

Wear items falling off.

(2) After inspection, install the oxygen meter and test whether it is unblocked. Install oxygen cores and humidification bottles, and check whether these devices are stable and in good working condition.

(3) Check whether the date of the oxygen tube is within the warranty period. Check whether there is any sign of air leakage and ensure that the oxygen suction tube is in good condition. Connect the oxygen suction pipe with the humidification bottle to ensure a stable connection. At the same time, turn on the switch to adjust the oxygen flow.

(4) Check the oxygen pipe again and test whether it is unblocked and has no leakage. Check whether there is water at the end of the oxygen pipe. If there are water drops, wipe them dry in time.

(5) Connect the oxygen pipe with the head mask, and ensure that the connection is intact to ensure that there will be no problems in the working state. After checking, put on the oxygen mask. The tightness of the upper cover and the comfort of the nose clip should be adjusted.

(6) After wearing the oxygen mask, record the time and flow of oxygen inhalation in time, carefully and carefully patrol back and forth, and observe the oxygen inhalation state to see if there is any abnormal performance.

(7) After the oxygen consumption time reaches the standard, stop using oxygen in time, remove the mask, turn off the flowmeter in time, and record the oxygen consumption time.

2. Usage of oxygen masks for civil aviation

(1) After the oxygen mask falls off, pull it down hard. There is a tight rope between the mask and the oxygen generator. Pulling this rope can trigger oxygen. Be careful not to use too much force to avoid breaking the fastening rope and the catheter.

(2) Put the mask on the mouth and nose to breathe normally. Generally, when the oxygen mask is released, there will be graphics and text instructions on the release board on how to use it. Passengers should operate correctly according to the instructions.
