arterial blood pressure. Questions: 1. My blood pressure for this lab was 123/78. These numbers are normal‚ compared to the normal rating of 120/80. My pulse pressure was 45 (SP – DP). My mean arterial pressure was 93 (DP + 1/3 (SP – DP). 2. Mean arterial blood pressure is determined by cardiac output and total vascular resistance. The mathematical equation for mean arterial blood pressure is equal to cardiac output x total vascular resistance. The amount of blood pumped out of the heart is the

This lab experiment investigates the effect of listening to different types of music on one’s pulse. The experiment relates the circulatory system to the pulse as it measures how quickly the heart contracts and releases blood. Pulse is measured in beats per minute (bpm). One’s pulse is loudest near the heart‚ because there is more pressure closer to the heart. In contrast‚ one’s pulse is quieter the further away it is measured from the heart‚ because there is less pressure the further the distance

Investigative Quest The purpose of this experiment was to find out how music affects the female human heart rate. Hypothesis My hypothesis is that female resting heart rate will increase as the music tempo increases. If the tempo is slower the heart rate will stay at resting heart rate or decrease. Variables The variables used in this experiment were: • The tempo of the music. • The subject’s heart rate. • The subject’s age. Controls The controls used in this experiment were: • How long the

THE EFFECTS OF COLD ON BLOOD PRESSURE AND PULSE Abstract The ability known as thermoregulation is a feature of an organism that help to keep the body temperature within certain thresholds‚ thus independently from external conditions. A dynamic state of thermal balance of human body between its internal environment and the territory is a model example of precise control of organism heat. In the case where such stability would be disturbed the immediate response would appear as well. In accordance

The Effect of Position on Heart Rate This lab explores the effect of head position on an individual’s heart rate by having a subject move it’s head while simultaneously monitoring the subjects heart rate. There were three successive periods during which the heart rate was monitored that occurred in this order: a resting stage (subject sitting upright)‚ a stage with the head positioned between the knees‚ and a recovery stage (subject returns to upright position). The graph depicts a wide range

Time (Minutes) | Pulse Rate(Beats/30 seconds) | Pulse Rate x2(Beats/minute) | Lying Down | 1 | 24 | 48 | Standing Up | 1 | 30 | 60 | Pulse Rate after 15 seconds of exercise (Beats/15 seconds) | Pulse Rate x6 in order to measure beats/minute(Beats/minute) | 11 | 66 | 3. Record how long this takes in seconds. - 38 seconds 4. Calculate the increase in the pulse rate immediately after the 15 seconds exercise compared with your standing rate. 66-60= 6. 6 pulses increased after 15

The purpose of this practical is to investigate how the pulse rate of humans changes when they exercise. Someone who is physically fit can supply their muscles with enough blood‚ carrying glucose and oxygen‚ for an activity at a lower heart and breathing rate. The fitter you are the lower your resting heart rate. You and your classmates will be the humans investigated. SAFETY: If you know you have any condition that affects you doing exercise‚ please make sure your teacher knows before you start

Caffeine’s Effect on Blood Pressure in Teens Research Questions How does the caffeine in coffee affect the blood pressure in teens within an hour? Purpose The purpose of the lab is to see the different effects of coffee in teenagers who have a different lifestyle. Also‚ my purpose is to be informed as well considering I’m a 17-year-old teen that drinks coffee on a regular base. I would like to know how all the coffee I have ever drunk‚ has had an effect in my body that I’m not aware of. Hypothesis

High or Low Blood Pressure? Purpose: The purpose of this experiment is to compare blood pressure as related to gender and athletic status. Hypothesis: I predict that males have a higher blood pressure than women and athletes have a higher blood pressure than non athletes Background Info: Blood pressure is the amount of force that blood pushes against the inside walls of blood vessels as it passes through. This pressure

L- Today in lab I practice how to assess a radial and brachial pulse. E- Initially‚ Hope explained where the radial and brachial pulse would be found and the proper position of the patient to accurately assess the pulse at both sites. Additionally‚ Jackie instructed us to use outside sources to draw where the brachial‚ radial and ulnar arteries run. To practice taking pulses‚ we worked with partners with as many classmates as possible to assess a variety of pulses and better understand possible differences
