At what PSI should the usage of the POB discontinue?

The usage of the Portable Oxygen Bottle (POB) should discontinue at 200 PSI. This is based on standard safety guidelines that ensure an adequate oxygen supply for both patient and operator safety during emergency situations. Continuing to use an oxygen bottle below this pressure could lead to insufficient oxygen availability for the patient, which may hinder effective treatment.

The 200 PSI threshold allows for a safe margin of oxygen to remain in the bottle while ensuring that the possibility of running out of oxygen too soon is minimized. Following this standard is crucial for maintaining the efficacy of emergency care and optimizing patient outcomes during critical moments.
