This can be calculated from the percentage of oxygen in the gas mixture (usually 100% in HBOT; 21% if using air) and multiplied by the pressure.
Dëst kann aus dem Prozentsaz vu Sauerstoff an der Gasmischung berechnen (normalerweis 100% an der Oxygentherapie; 21% wann et Loft gëtt) a multiplizéiert duerch den Drock.
