[0002] Hyperbaric oxygen chambers are used to assist in regulating the body by delivering high-concentration oxygen (the air pressure in the confined space is higher than the normal atmospheric pressure) to a confined space through a pressurized chamber. At present, the hyperbaric oxygen chambers on the market are not only used in the medical field, but also gradually appear in civilian hyperbaric oxygen chambers for health care. Civilian hyperbaric oxygen chambers have lower relative pressure and higher safety. They are suitable for the elderly, patients with chronic diseases, beauty lovers, sub-healthy people, athletes, obese people, postoperative rehabilitation patients, etc. Hyperbaric oxygen chamber equipment is commonly found in a variety of scenarios such as nursing homes, rehabilitation centers, home physiotherapy, medical beauty institutions, gyms, high-end hotels, confinement centers, community elderly care, gymnasiums, high-end clubs, plateau areas, etc.

[0003] During the use of the hyperbaric oxygen chamber, personnel enter the chamber and stay there for a long time. Due to the poor ventilation conditions in the space, personnel are prone to suffocation. Existing hyperbaric oxygen chambers mainly use sensors to detect the content of a certain gas in the confined space to send out sound and light warnings to remind people in the confined space, which has a lag; people stranded in the confined space may have fainted or collapsed due to the increased content of a certain toxic gas and cannot rescue themselves. Since the early warning information cannot be issued in time, there will be a risk of suffocation and death. Therefore, there is an urgent need for a monitoring system for hyperbaric oxygen chambers that can promptly remind people in the confined space to leave voluntarily, and for those who cannot leave voluntarily, a distress signal can be sent.
