How to use the hyperbaric oxygen chamber? Step one, open the lid above the oxygen machine and remove two transparent tubings and one bracket inflatable adapter. Connect one end of the inflation pipe to the bracket inflation conversion head, and the other end to the oxygen machine outlet. Open the valve lid of the inflatable bracket and press the inner core twice, making sure the inner core is convex from the outside. Turn on the oxygen machine switch by tightening the inflation port of the inflation adapter into the bracket. The inflation time is usually about 3 minutes, and the oxygen machine is turned off after the hardness of the inflatable bracket reaches the hardness that can be supported. Unplug the inflatable tube and tighten the nozzle cap. Step two, remove the adapter to access the cabin air intake. The other trachea is connected to the oxygen outlet of the oxygen machine at one end. The other end is connected to the oxygen inlet of the cabin. Close the manual bleed valve clockwise. After entering the cabin, the human body needs to close the internal and external zippers of the cabin.
