What should happen to the gauge during POB checks?

During Portable Oxygen Bottle (POB) checks, the gauge must indicate a pressure between 1500 psi and 1850 psi. This pressure range is important because it ensures that the oxygen supply is sufficient for emergency situations. If the pressure is below 1500 psi, there may not be enough oxygen available, which could jeopardize patient care in emergencies. Conversely, if the gauge indicates pressure above 1850 psi, it may signal that the bottle is over-pressurized, which could pose a risk during use or storage. Therefore, maintaining the gauge within the specified range indicates that the equipment is adequately prepared for effective emergency response.
