How long does the Portable Pulse Oxygen Bottle (PPOB) last?

The Portable Pulse Oxygen Bottle (PPOB) is designed to provide supplemental oxygen to passengers who require it during a flight. The correct duration that the PPOB lasts is 180 minutes. This extended duration is essential for accommodating various situations that might arise during a flight, ensuring that passengers have adequate oxygen support over an extended period. It is particularly important on longer flights or in scenarios where the aircraft may experience deviations from planned altitudes or delays.

Having a PPOB that can last for 180 minutes allows flight attendants and medical personnel to manage the needs of affected passengers confidently and effectively, enhancing safety and comfort. Understanding the operational capabilities and limitations of such equipment is crucial for inflight services, as it directly impacts the care that can be provided to passengers in need of oxygen.
