Some hospitals have built high pressure chambers in which patients can breathe high pressure air or oxygen. Hyperbaric therapy is often used when the patient's tissues or blood need higher than normal concentration of oxygen. It can effectively treat carbon monoxide poisoning and respiratory disorders, and it is also very promising in combination with surgery. The use of decompression technology is similar to its use in deep-sea diving.

 For inhalation therapy, clean, dry air is supplied with a positive pressure of several inches of water to the respirator in the non pressurized treatment room. Usually, oil-free compressors are used to provide compressed air for hospitals. In an optional system that provides breathing air (patients can easily use it in hospitals or at home), oxygen rich air passes through a molecular sieve filter to remove nitrogen from the atmosphere. After this oxygen concentration process, the oxygen concentration can reach 90% to 95%.

 The high-speed turbine driven pneumatic surgical drill has exciting capabilities. In cranial surgery, it can shorten the time for surgeons to remove the skull to two minutes, while using hand tools takes half an hour. It can also be used to cut the transplanted thoracic cartilage to form an artificial ear, and to shape the graft bone to rebuild a severely damaged nose. The pneumatic drill is very light, but it improves the speed and power of bone cutting, drilling and molding. Compressed air or nitrogen that provides power is discharged at the tip of the drill to cool the cutting area.
