1 Cardiac Vital Measurement Lab In this activity, you will learn and practice many of the techniques used in the health/ medical profession for assessing a patient's cardiac health. 1

2 By now you should know the difference between heart rate, pulse rate, blood oxygen saturation level, and systolic blood pressure and diastolic blood pressure). *Form hypotheses (5 total), using if then statements, for each measurement predicting the percent increase or decrease from resting to right after aerobic exercise. You may write this as one if then statement as long as you predict all 6 measurements. *Form another hypothesis predicting how many seconds it will take your body to return to a normal pulse rate after exercise. 2

3 1. Create a data table in a spreadsheet. 2. Record your values while at rest (sit quietly for 5 minutes before taking the measurements): pulse rate (beats per minute) blood pressure (systolic/diastolic) oxygen saturation level (record %) heart rate (use a stethoscope record beats per minute). 3. Exercise vigorously for at least 5 minutes. 4. Sit down, then measure your vitals and record. 5. After 2 minutes of rest, record your heart rate and record. 5. In your data table, include all members of your group plus one additional person from the class (the additional person may not be used by anybody else in your group). 6. In your spreadsheet data table, calculate the % difference from rest after exercise for each measurement: R = Resting value E = Value right after exercise (E R/R)= % difference Example 25% means your rate increase 25% over resting. 10% means you decreased 10% from resting. 7. Calculate the average heart rate after 2 minutes of rest after exercise. 8. Calculate the Heart Recovery Rate by subtracting the heart rate 2 minutes after exercise from the heart rate right after exercising. 3

4 Blood Pressure Category Normal Systolic Diastolic mm Hg (upper #) mm Hg (lower #) less than 120 and less than 80 Prehypertension or High Blood Pressure (Hypertension) Stage 1 High Blood Pressure (Hypertension) Stage 2 Hypertensive Crisis (Emergency care needed) or or higher or 100 or higher Higher than 180 or Higher than 1 From the American Heart Association 4

5 Lab Report (all parts required to be typed and computer generated): Your original Hypotheses Data Tables Graphs *Lab Analysis (follow the format used in class) Work Cited/Bibliography *In the analysis, address the results by compare the average student results (% difference) and data range (min max values) to your hypothesis. 5

6 Graphs: Create 5 bar graphs, each comparing the results (% difference) for the students in your group: Heart Rate Pulse Rate O 2 Saturation Level Systolic Blood Pressure Diastolic Blood Pressure Make another bar graph comparing the average student result for: Time in Seconds to return to resting pulse rate 6

7 Additional Questions: Describe the difference between heart rate and pulse rate. What is each measuring? Be specific. What is hypertension? Research and describe three harmful effects of long term hypertension in a human. Then, describe three contributing factors that cause hypertension. Cite your source(s) within your analysis then include a bibliography. Analyze your heart recovery rate and compare to the inferences listed below. How does your heart rate compare? Subtract your 2 minute heart rate reading from the heart rate soon after exercise cessation. According to the New England Journal of Medicine (2016), the bigger the difference, the healthier your heart is. Here are a few inferences (assuming you vigorously exercised) If the difference between the two heart rates is less than 22, your real age of heart is slightly more than your biological age (that calls for lifestyle and dietary modification). If the recovery heart rate difference is in between beats per minute; your biological age (or calendar age) is approximately the same as that of your heart age/ real age. A recovery heart rate difference of beats per minute indicates optimal health, healthier heart and a real age of less than calendar age. If the difference of your immediate post exercise heart rate and heart rate after 2 minutes is in the range of beats per minute, your heart is healthier and your real age is moderately less than your biological age. With a difference of more than 66, your heart is very healthy and your heart physical age is a lot less than your calendar age.
