M3 WORKSHEET INTRODUCTION TO DATA ACQUISITION AND ANALYSIS 1. Measure pulse amplitude from the finger pulse waveform of each group member and record your results in table 1. (20 pts) Table 1: Finger pulse amplitude. 1 2 3 Mean SD Group Member 1 0.066 0.051 0.060 0.059 0.006 Group Member 2 0.068 0.054 0.038 0.053 0.012 Group Member 3 0.042 0.046 0.098 0.062 0.026 Group Member 4 2. In what unit of measurement should you report finger pulse amplitude? Why? (6 pts) Volts because that indicates the intensity of the electric signals creating the pulses. 3. Measure pulse duration from the finger pulse waveform of each group member and record your results in table 2. (20 pts) Table 2: Finger pulse duration. 1 2 3 Mean SD Group Member 1 0.502 0.336 0.520 0.453 0.083 Group Member 2 0.182 0.192 0.158 0.177 0.014 Group Member 3 0.123 0.176 0.144 0.148 0.022 Group Member 4 4. In what unit of measurement should you report finger pulse duration? (6 pts) Seconds. 5. Measure cardiac cycle duration from the finger pulse waveform of each group member and record your results in table 3. (20 pts) Table 3: Cardiac cycle duration. 1 2 3 Mean SD Group Member 1 0.782 0.736 0.780 0.766 0.021 Group Member 2 0.540 0.366 0.706 0.537 0.139 Group Member 3 0.631 0.870 0.706 0.736 0.100 Group Member 4 6. In what unit of measurement should you report duration of a cardiac cycle? (6 pts) Seconds. 7. Calculate the heart rate of each group member and record your results in table 4.

M3 WORKSHEET Table 4: Heart rate. Group Member 1 78 Group Member 2 112 Group Member 3 82 Group Member 4 8. Briefly explain how you chose to calculate heart rate. (6 pts) I calculated it by dividing one minute by how many seconds it took for one heartbeat to occur. This equals to (60 seconds)/(mean cardiac cycle duration) for each group member. 9. In what unit of measurement should you report heart rate? (6 pts) Beats per minute. 2 Boswell LC (Spring 2024) Vertebrate Physiology Student Lab Manual . Baton Rouge, LA: Louisiana State University.
