The use of GSH-6 in good condition and its difference from oxygen masks. Hermetic helmet GSH-6A, GSH-6M, are used to perform high-altitude flights of more than 14 km. Unlike the mask, the air mask completely isolates the pilot's head from the external hostile environment, while it has all the functions of an oxygen mask.
The main feature of GSH is that it provides full compensation for the head with excessive pressure in the lungs, in fact, the pressure in the lungs is almost equal to the pressure in the under-helmet space, thanks to this, oxygen entering a person under pressure does not try to find a natural loophole through the ears and eye slits.
