How to adjust the air pressure of portable oxygen bottle kitten

Portable oxygen bottle kitten air pressure adjustment steps are as follows:

1. Take out the active oxygen of Airun, take out the nasal straw, and straighten both ends of the straw by hand to ensure that the straw is unobstructed and connected with the oxygen bottle.

2. When turning the switch of the regulating valve, put the nose suction head next to the ear first, and feel that there is gas flowing out, but you can't hear the sound of "before". Then put the nose suction head into the nostril, adjust it to the right size, and breathe normally.

3. After use, clean the oxygen cylinder for next use.
