How to Read an Oxygen Regulator

Oxygen therapy is used in the treatment of a variety of respiratory ailments. Oxygen is frequently provided to patients in their homes with the help of oxygen cylinders and regulators. These regulators come in a variety of shapes and sizes, but their functions are more or less the same. They serve to step down the pressure of the oxygen to a usable level. By reading the regulator, you can see exactly how much pressure is left within the cylinder.
