Heart Rate & Blood Pressure Lab You are a medical intern finishing your last year of residency in med school. A 20-year-old granddaughter has brought their 80-year-old grandma to your office for a checkup. After doing a thorough physical, you find that the grandma needs some exercise to improve her heart rate (HR) and blood pressure (BP). The granddaughter is an athlete who says she will help her grandma train to have a HR and BP just like herself. Your medical training has taught you that regular exercise will prevent hypertension and high BP. But at med school, an athlete has significantly different HR and BP than a non-athlete. You’re not sure whether an athletic HR and BP will be good for the 80-year-old. You decide to do an experiment to compare your own HR and BP to the HR and BP of a typical athlete who plays land sports (ie. Basketball, soccer, baseball, etc.). Purpose: 1. Do athletes have high or lower HR than a non-athlete? 2. Do athletes have high or lower BP than a non-athlete? Hypothesis: Click on the link on the website and provide 2 hypotheses. Equipment: q Stethoscope q Sphygmomanometer q Timer q BYOB Caffeine beverage (optional—just for fun) Pre-lab procedures: q Watch the video posted on the website and read the lab instructions on How to Measure Blood Pressure before the lab q Read the How to use the Prelab Sphygmomanometer Instructions q If students choose to perform the optional caffeine activity, students must bring their own caffeine beverage and abstain from drinking any caffeinated beverage 8 hours prior to the lab q Wear appropriate attire that allows the stethoscope to be placed on your chest and the sphygmomanometer to be placed around the upper arm. Safety: q Students who have pre-existing medical conditions (eg. Anemia, asthma, heart or respiratory conditions, etc.) should notify their teacher and arrange for adaptations to the lab. q Watch your partner to see if they are in medical distress. Call the teacher immediately if you suspect your partner is not well. q Clean your stethoscopes before and after use with the cleaning wipes. Do not share stethoscopes.

Procedures: q Doctor measures the patient’s Blood Pressure q Patient can measure their own Heart Rate by feeling their carotid artery. Part A: REST positions. 1. Place your finger on your carotid artery by your neck. 2. Listen for your heart beat in the following positions: lying down , sitting , and standing . To calculate the heart rate (HR), set a timer for 30 seconds and count the number of beats. Multiply by 2 to find your HR per minute 3. Set the stethoscope to the ON position (if required on your stethoscope) 4. To find the blood pressure (BP) Wrap the sphygmomanometer around the upper arm just above the elbow. 5. Place the stethoscope on the brachial artery. 6. Raise the pressure to 140-160 mm Hg so the heartbeat cannot be heard 7. Continue listening and slowly release the pressure. Listen for the first beat to sound. This is the systolic pressure. 8. Continue listening as the sound begins to fade. When the sound is completely gone, this is the diastolic pressure. Practice a few times until you get it right. Part B: BREATHING Exercises 1) While sitting , hold your breath for as long as comfortably possible. 2) When you are ready, start breathing again. Repeat steps in Part A to measure your HR and BP 3) Switch with your partner and repeat Steps 1 & 2. 4) While sitting , hyperventilate by inhaling and exhaling as fast as you can for 1 minute. 5) When you are ready, use the stethoscope and sphygmomanometer to take HR and BP. Part C: STRENGTH TRAINING 1) Perform as many pushups as you can in 1 minute. 2) Perform as many squats as you can in 1 minute. 3) Use the stethoscope and sphygmomanometer to take HR and BP. Part D: Just for Fun 1) Drink a caffeine beverage and wait 10 minutes. 2) Use the stethoscope and sphygmomanometer to take HR and BP Observations/ Questions/ Conclusion: Click on the link on the website to fill in your results.
