What is the duration for a single HI flow, small mask?

• A. 20 minutes
• B. 70 minutes
• C. 25 minutes
• D. 60 minutes

Answer: (A)

High-flow therapy delivered through a small mask is typically given in short, defined bursts to balance effective therapy with safety and reassessment. A single HI flow session is commonly set at about 20 minutes. This duration allows clinicians to monitor oxygenation and comfort, adjust settings as needed, and decide whether to continue, pause, or stop the treatment. Longer runs, like 60 or 70 minutes, reduce opportunities for timely evaluation and can increase risks, while 25 minutes isn’t the standard interval used in typical protocols. So, 20 minutes best fits the usual practice for a single HI flow with a small mask.
