What is the duration of the low outlet for a standard portable oxygen bottle?

The duration of the low outlet for a standard portable oxygen bottle is indeed 150 minutes. This figure is based on the typical flow rate and oxygen capacity of standard portable oxygen systems used on aircraft. Understanding the duration is crucial for flight attendants, as it helps to ensure passenger safety and health in cases where supplemental oxygen is necessary during flight.

Flight attendants must be knowledgeable about the longevity of oxygen supplies in order to perform their duties effectively, particularly in emergency situations. Each portable oxygen bottle is designed to deliver a consistent flow rate, and the 150-minute duration represents an average calculation based on that flow rate. This information is essential for managing oxygen supply in emergencies, thus ensuring that all passengers receive adequate oxygen if needed.
