Variables Affecting Human Arterial Pressure and Pulse Pressure BIOL 204-506 Remi Ben-Davies Dashaun Lee‚ Amanda Easter‚ and Lynne Baker April 9th‚ 2015 1 Introduction: Purpose: The purpose of this experiment was to determine how different variables may affect arterial pressure and pulse rate. Two subjects were used as models for the tests. The first two tests required the use of sphygmomanometers and stethoscopes to measure the arterial pressure and pulse rate. The last test required sphygmomanometers

Engr 4132 Biomedical Engineering Lab Dr. Gang Xu Lab #9: ECG & Pulse Mechanical Action of the Heart Peripheral Pressure Pulse Plethysmography By: Abigail Magee Partners: Lauren Tinnin Nick Walker Date: 11/05/2015 Introduction: The heart goes through a cardiac cycle in order to pump blood throughout the body. This cycle is started by electrical activity that can be measured by an electrocardiogram. As the heart contracts‚ it pumps blood into the next section of the cardiac

(a) Give generalized conclusions (in point form) according to your observation in (a). 1. systolic pressure increases when the degree of exercise increases Systolic pressure increases gradually from 115 mmHg at rest to 150 mmHg during severe exercise. When thr degree of exercise increases‚ the skeleton muscle needs more energy(ATP) for rapid contraction by carrying out aerobic respiration. The skeleton muscle required faster uptake of oxygen and removal of carbon dioxide. At the same time‚ skeleton

Vapor Pressure and Heat of Vaporization Introduction: Evaporation is the process of a liquid becoming vaporized. When a liquid is placed into a confined space some of the liquids will evaporate. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules. During the evaporation process of the liquid‚ new gas molecules exerts pressure in the sealed container‚ while some of the gas condenses back to the liquid state. If the temperature inside

Objective: Use cuff manometry to measure 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

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

24-Hour Blood Pressure Monitoring In some patients‚ an elevated blood pressure reading taken during an office visit may not truly indicate hypertension—it could just be an occasional occurrence. These individuals are given a portable device to record their blood pressure over a 24-hour period. This helps us more accurately determine whether or not a patient usually has high blood pressure and requires treatment.
