How is respiration measured correctly?

• A. Count breaths for 15 seconds.
• B. Observe chest rise and fall for 60 seconds, noting rate, depth, and rhythm.
• C. Listen for breath sounds with a stethoscope.
• D. Palpate abdomen to estimate breaths.

Answer: (B)

Measuring respiration correctly centers on watching the chest rise and fall for a full minute to determine rate, depth, and rhythm. By counting the number of breaths in 60 seconds, you get an accurate rate and you can notice if breaths are shallow or deep and whether the breathing pattern is regular or has pauses or irregularities. Shorter counts, like 15 seconds, can lead to errors because breaths may be uneven or you might miss temporary changes in the pattern. Listening with a stethoscope checks breath sounds, not the actual rate or pattern of breathing. Palpating the abdomen to estimate breaths isn’t reliable for measuring overall respiration because some people primarily use chest breathing, some abdominal, and the goal is to observe the actual movement of the chest to capture rate, depth, and rhythm.
