In high-frequency ventilation terminology, 1 Hz corresponds to how many cycles per minute?

• A. 30
• B. 60
• C. 120
• D. 1

Answer: (B)

Hz represents cycles per second, so 1 Hz means one cycle each second. Since there are 60 seconds in a minute, 1 Hz equals 60 cycles per minute. This conversion helps interpret HFV settings, where the frequency in Hz can be translated into cycles per minute as needed. For reference, 0.5 Hz would be 30 cycles per minute, 2 Hz would be 120 cycles per minute, and 1 cycle per minute would be 1/60 Hz.
