Cabin crew must monitor a passenger's Medipak every how many minutes to ensure content doesn't fall below 100 psi?

• A. Every 5 minutes
• B. Every 10 minutes
• C. Every 15 minutes
• D. Every 30 minutes

Answer: (C)

Maintaining a safe oxygen supply by tracking the Medipak pressure is essential, since the contents decrease as they’re used and must stay above a safety threshold of 100 psi. Checking every 15 minutes provides a timely detection window for typical usage, allowing you to replace or secure a backup before pressure falls below 100 psi. Checking more often would be unnecessarily burdensome, while waiting too long—like 30 minutes—could let the pressure drop below the minimum before you notice it. Therefore, monitoring at 15-minute intervals best protects the passenger’s oxygen supply.
