A complete treatment process is mainly divided into the following three stages, and the time allocation for each stage is as follows:
Pressurization stage (about 15-20 minutes): After the patient enters the cabin, the pressure in the cabin will slowly increase to the pressure required for treatment (usually 1.5-2.5 atmospheres). Patients at this stage may feel slight pressure or swelling in the ears, which can be relieved by swallowing, yawning, or pinching the nose and blowing air.
Stable pressure oxygen inhalation stage (about 60-90 minutes): After the pressure reaches the target value, the patient inhales pure oxygen or high-concentration oxygen through a mask or hood. This phase is the core of treatment. The patient needs to remain quiet and may rest or take a nap. Some treatment plans will use "intermittent oxygen inhalation" (such as inhaling oxygen for 30 minutes, resting for 10 minutes, and then inhaling oxygen for 30 minutes) to avoid the risk of oxygen poisoning.
Decompression phase (about 15-20 minutes): After oxygen inhalation is completed, the pressure in the cabin will slowly drop to normal levels, and the patient will exit the cabin.
Time difference description:
Acute and severe cases (such as acute carbon monoxide poisoning): The first treatment time may be relatively long (nearly 120 minutes) in order to quickly correct the body's hypoxic state.
Chronic disease or recovery period (such as insufficient blood supply to the brain, brain trauma rehabilitation): a single treatment may be relatively short (60-90 minutes), and symptoms will gradually improve through multiple treatments.
Special illnesses (such as decompression sickness): In some special cases, the treatment time may be extended to 2-3 hours or more.
