A typical nominal regulated gauge pressure from a medical oxygen regulator is 3.4 bars (50 psi), for an absolute pressure of approximately 4.4 bar and a pressure ratio of about 4.4 without back pressure, so they will have choked flow in the metering orifices for a downstream (outlet) pressure of up to about 2.3 bar absolute.
A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.
Air from the diving cylinder is subjected to a dramatic reduction in pressure - as much as 220 bar (3,200 psi) from a full 230 bar (3,300 psi) , and 290 bar (4,200 psi) from a full 300 bar (4,400 psi) cylinder at the surface - when passing through the regulator first stage.

The ambient pressure at the surface is 1 bar (15 psi) at sea level. For every 10 metres (33 ft) in seawater the diver descends, the pressure increases by 1 bar (15 psi). [79] As a diver goes deeper, the breathing gas is delivered at a pressure equal to ambient water pressure, and the amount of gas used is proportional to the pressure.
The absolute pressure on an ambient pressure diver is the sum of the local atmospheric pressure and hydrostatic pressure. [ 5 ] [ 6 ] Hydrostatic pressure is the component of ambient pressure due to the weight of the water column above the depth, and is commonly described in terms of metres or feet of sea water .
