How ting heart rate the pulse with ty, rhythm, and we palpate the can be graded the body PROCEDURE Palpating Pulse and Calculating Pulse Rate before and after Exercise 1. For a review of pulse points, go to EXERCISE 18 in the Study Area of Mastering AP and watch the Pre-Lab Video Pulpting the Superficial Pabe Points 2. Refer to FIGURE 18.20 to locate the radial artery in your non-dominant arm. While seated, use two fingers of your dominant hand to palpate the radi al pulse. Do not use your thumb, as it has a promi pent pulse that can be confused with the pulse you are attempting to measure. 3. Sit quietly for 1 minute (60 seconds) with your legs and feet uncrossed. Then count the number of pulses for 15 seconds. Multiply this number by 4 to calculate the number of beats in 60 seconds This 1-minute pulse rate is your resting heart rate Record this number in TABLE 18.6. 4. Note the characteristics of the pulse, and grade the pulse using the standardized pulse scale (see TABLE 18.5) Record the pulse grade and characteristics in TABLE 18.6.

Immediately take your pulse again following the process described in steps 2 and 3. Note your pulse rate, grade, and any changes in the pulse charac teristics. Record your results in TABLE 18.6. 7. Answer the following questions: (a) What causes a pulse? How are heart rate and pulse rate related? (b) What is the normal resting heart rate range for healthy adults? How does your resting heart rate compare to the normal range? If any dif ference exists, suggest some reasons for the difference.. (c) How did exercise affect pulse rate? Why did a change in pulse rate occur? (d) Hypothesize how body position affects pulse rate.
