1. Before use, check whether the connecting parts of oxygen cylinders are leaking. It can be coated with soap solution for inspection and can be used only after it is confirmed that there is no air leakage.
2. After confirming that the pressure reducing valve is closed (T-shaped adjusting screw is loosened), open the cylinder master valve counterclockwise, observe the reading of the high pressure meter, then open the small switch on the left side of the pressure reducing valve counterclockwise, and then slowly turn the pressure reducing valve adjusting screw (T-shaped rotating rod) clockwise to compress the main spring to open the valve. Keep the pressure on the pressure relief gauge at the required pressure.
3. After use, turn off the cylinder master switch clockwise, and then unscrew the pressure reducing valve counterclockwise.
4. Finally, after oxygen inhalation, close the valve of the gas cylinder, close the regulating valve when the small floating ball of the flowmeter returns to zero, and take out the nose of the straw from the nostril.

Benefits of using portable oxygen cylinders:
1, oxygen inhalation with portable oxygen bottle can relieve angina pectoris and prevent the occurrence of myocardial infarction: angina pectoris is caused by acute myocardial hypoxia, which can cause myocardial infarction for more than 30 minutes, which is a disease.
People die of pain as the main risk factor. Regular health care and oxygen inhalation or oxygen inhalation at onset can prevent or alleviate the occurrence of angina pectoris and myocardial infarction and buy time for treatment.
2. Using portable oxygen cylinders to absorb oxygen can prevent painful coronary heart disease: sudden coronary heart disease is hard to prevent because of its special onset. Persistent mild brain tightness, shortness of breath, abnormal mood or heart rate disorder often occur before onset.
If oxygen therapy can be supplemented at this time, you can get twice the result with half the effort.
