However, it is important to understand that these cylinders must be managed in accordance with series of factors, and variables, that will make the use of them safe por a patient. One such really important variable is the residual pressure within a cylinder, which means the pressure exerted by the oxygen available still in the cylinder as it flows. Universally it is accepted that the minimum level of this residual pressure must be 200 psi (pounds per square inch) and once it reaches here it means that once that levels has been reached, it is no longer safe to use that cylinder anymore.
