When stopping oxygen supply, the correct operation method is as follows:
1. Turn off the oxygen cylinder: firstly, turn off the oxygen cylinder, turn off the switch or knob of the cylinder in turn, and completely close the oxygen channel to ensure that oxygen no longer flows.
2. Unplug the oxygen mask or catheter: gently remove the oxygen mask or catheter from the patient's nose or mouth to ensure that the patient can breathe smoothly and breathe normally through his own breathing.
3. Observe the patient's condition: after stopping oxygen, it is necessary to continue to observe the patient's breathing state and consciousness level to ensure that no abnormal situation occurs. If the patient has unwell symptoms, measures should be taken in time.
4. Shut down the oxygen system: shut down the oxygen flowmeter, cut off the oxygen pipe connection, install the explosion-proof cover, and completely shut down the oxygen system to ensure safety. At the same time, make sure that the pressure at the top of the oxygen bottle has dropped to zero, and then tighten the bottle cap.
5. Recording: After oxygen cessation, it is necessary to record the patient's breathing state and oxygen cessation time as a reference for the next oxygen use.
The above is the correct operation method when stopping oxygen, because oxygen is a special medicine, and it needs special surgical operation training and proficiency before operation. In order to ensure the safety of patients, it is recommended to operate under the guidance of professionals.
