The Pulse and heart rate preset settings can be used together with a finger pulse transducer to measure your heart rate.
Exercises you can do with these settings
- With the Pulse Transducer attached to the distal segment of a volunteer's middle finger, investigate whether there are any rhythmic variations in heart rate during quiet breathing.
- Alternatively, use the Pulse Transducer to visualize the waveform of the radial pulse during the cardiac cycle (see equipment setup image below).
- Count the number of pulses in different time periods (e.g. 15, 30, and 60 seconds) and calculate the heart rate as you would in a clinical setting.
The following instructions may be useful for you to copy and paste for your students:
Equipment setup procedure
- Connect the Pulse Transducer to Input 1 on the PowerLab.
- Attach the Pulse Transducer to the volunteer's middle finger.
- Alternatively, palpate the radial pulse of your volunteer, then place the pressure pad of the Pulse Transducer against their radial artery, as shown in the image below.
