NO ... this is dangerous, take your tank to a professional depot that does this , but remove the regulator first.
You "crack" an oxygen tank by opening the cylinder's main valve briefly to blow out contaminants from the main valve before attaching the regulator. This is done because contaminants inside the valve or at the valve outlet (dust, dirt, organic material, bugs, fragments of plastic from valve seats, etc.) act to initiate regulator fires and explosions ignited by heat from adiabatic compression of oxygen into the regulator when the oxygen main valve is first opened. These fires ignite the brass regulator itself and are very dangerous. They are avoided by keeping oxygen equipment clean, by cracking a new oxygen cylinder prior to use, and by opening the main valve slowly when a regulator is attached.
A hospital could buy an oxygen regulator from a store that carries medical supplies in Las Vegas. If there is no such establishment, one could go on Amazon.
When "bleeding" an oxygen tank, you are releasing excess pressure stored in the regulator, not the tank itself. If the excess pressure remains, it can damage the regulator, and the guage needle can get stuck, giving an inaccurate reading of how much oxygen remains in the tank.

Krakauer felt better after harris turns the valve on the regulator because he wanted to conserve his oxygen tank.
the threads on a acetylene bottle are anti clockwise so on oygen bottle its righty tighty on acetylene its lefty tighty
The air is super compressed either in gas or liquid form in a pressurized tank. A regulator is attached and lets only a certain amount of psi through at a time. Without this regulator the bottle would take off like a rocket to the moon if it were to open somehow.
With scuba diving, you are diving with an oxygen tank on your back and a regulator in your mouth. For SNUBA, there isn't an oxygen pack on your back, instead your oxygen supply is a long hose attached to a raft on the surface of the water.
oil residue in an oxygen regulator connection may cause an explosion. Also when oxygen is mixed in a refrigeration system with a refrigerant like R410A which has oil in it, it can cause an explosion.
