Hyperbaric chamber (PAC, Certec or Gamov-bag) and oxygen
|
|
It consist of a polyamide bag which is adjusted with a manual pump to an overpressure of 220 mb (equivalent to 2 500 to 3 000 m of altitude). In order to use it, the person must not present breathing problems nor pressure compensation. Eventually, nasal drops must be given in order to diminish the inflammation in the nose mucose. The trunk must be kept slightly raised to an approximately 30º angle. Close the bag hermetically according to the instructions and inflate to the indicated pressure. Fresh air must be introduced into the pump every 5 minutes approx. Used air is automatically expelled through an overpressure valve. Pressure can be monitored through the included manometer or the altimeter situated in the chamber.
The chamber doesn’t replace the descent. After 1-2 hours of staying in the chamber, the patient is in conditions to descend or be transported without any danger. In addition, the person can take oxygen (4-6 lt/min) or medication.
