Step 2. Collect baseline data
Make a chart like this one in your lab notebook or on your device.
Tell the subject to sit quietly for a few moments.
Measure resting heart rate: Using the method shown in the photograph, the pulse taker locates where he or she can feel the subject’s pulse. When the timekeeper signals, the pulse taker counts the number of heartbeats in exactly 30 seconds.
Measure resting breathing rate: During the same 30 seconds, the breath counter observes the subject and counts the number of breaths he or she takes. Record your data in the table on the next page.
Repeat this procedure so you can find an average for accuracy. Remember to convert your data to a unit rate (per minute) by multiplying by 2.
When you have finished collecting baseline data for the first subject, continue Step 1 by rotating jobs until everyone in your group has had their resting heart rate and resting breathing rate measured.
