Cardiovascular Function Lab

The lack of knowledge and confidence of obtaining a manual blood pressure is an ever growing issue in the healthcare field. This paper will outline the importance of taking a manual blood pressure accurately. Providing the proper blood pressure measurement can determine a patient’s care and outcome when in a healthcare facility. I will talk about the pros and cons of manual blood pressures and personal experience of this vital skill in the healthcare field. I will also provide some simple but effect ways to increase confidence and knowledge by just basic education. All of my information and numbers will be supported by using references and studies in the use of manual blood pressure monitoring.

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

This experiment was carried out as noted about in Procedure 1. The resting heart rate was established and used as a baseline value from which to compare all future deviations. While data could

The authors then share their analysis on the changes of heart rate and GSR at the many different points throughout their study.

Using the lab activity, observe and record the physiologic changes that occur during exercising using the following chart:

The purpose of arterial pressure and the pulse lab is to determine the effect of posture and exercise on systolic and diastolic pressure and the heart rate. And also in order to find the differences in the reading taken under these condition compares to the baseline reading. The Sphygmomanometer and stethoscope are used to measure the systolic and diastolic blood pressure, counting the beat on the radial artery will give the reading for pulse rate and by using the lab scribe software and IWX214, the blood pressure will be measured. In the heart, the aorta and the carotid arteries have baroreceptors and the chemoreceptors that identify the changes in arterial pressure and the changes in

The effects of heart rate on differing durations of exercise were studied in this experiment. For people, heart rate tends to increase as they perform physical exercises. The amount of beats per minute gradually increases as people perform physical activities. Heart rates taken before exercise are relatively low, and heart rates taken one minute after exercise increase significantly. Heart rates slowly begin to decrease after they are taken two minutes and three minutes after performing the step test, which is to be expected. The rates of intensity throughout exercise relates with changes in heart rate throughout the step test performed in the experiment (Karvonen 2012). The age of the participants affected the experiment, since the heart rate during physical exercise, in this case the step test, is affected by age (Tulppo 1998).

Aims - This study is to ascertain, if there is an effect on heart rate after exercise. This is being done to see, if there is a difference between resting heart rate and heart rate after performing exercise.

The auscultatory method involves the use of a sphygmomanometer and a stethoscope to listen to Korotkoff sounds and determine the systolic and diastolic arterial pressure (Kapse & Patil, 2013). The mercury and aneroid sphygmomanometers are two types of devices that use auscultatory methods to measure blood pressure (Buchanan, 2009).

In the first part of the practical, we will dissect the heart of a sheep and observe its anatomical structure. We will also examine the structure of blood vessels at a microscopic level. My hypothesis is that by examining the anatomy of the cardiovascular system, we will be able to detect differences in both vessels and the chambers of the heart. In the second part of the practical we will examine the electrical activity of the heart. In doing so my aim will be to produce a familiar ECG reading containing a P wave, QRS complex and T wave. Futhermore, we will take blood pressure readings by listening to the korotkoff sounds of the heart using a sphygmomanometer and stethoscope. We hypothesis that the higher the arm position is from the ground, the smaller the blood pressure reading will

The reason why my fellow group members and I chose this activity was not only is it a fun and engaging activity, it helps strengthen your cardiovascular endurance. The main goal of this activity was to have the entire class participate and letting them build sportsmanship and strategy. The game capture the flag allowed each team to learn how to work together in order to win. Each team had to strategically plan out there idea of how they would succeed. Overall, I think the game went smoothly and everyone enjoyed themselves.

The effects of exercise on blood pressure, heart rate, respiration rate and electrical activity of the heart were assessed. The measurements of respiration rate, pulse rate and blood pressures were noted as described in Harris-Haller (2016). Data was first taken from subjects in a relaxed position and then followed by sets of reading after exercising based on one minute intervals. The data also noted sitting ECG traces from Harris-Haller (2016). The respiratory rate, pulse, blood pressure, P wave, QRS complex and T wave were defined for each subject. The class average was calculated for males and females and graphed to illustrate the results by gender for each cardiopulmonary factor.

With the information found with what a patient’s blood pressure is, it helps health care providers understand the state of the patient’s health. A patient’s blood pressure measures the amount of pressure exerted on arterial walls in the patient’s heart. Blood pressure is measured in two numbers: systolic and diastolic. Systolic, the number listed first in blood pressure readings, reports the amount of force exerted by the blood into the arteries during ventricular contraction.

The purpose of these lab exercises is to understand the function and importance of an electrocardiogram. This lab will demonstrate how stress levels or different elevations can affect human heart rate. Furthermore, the equipment used in the experiment will show the functions in the right and left arm; as well as, in the right and left ankles. Finally, the lab will serve a purpose as a way to know how to read an electrocardiogram and calculate the heart rate.

The heart rate is a measurement of how many times the heart beats in a minute. Physically fit people tend to have a lower heart rate and during intense exercise tend to have lower rates as well. A decrease of heart rate at both rest and at fixed intensity of sub-maximal exercise [7] occurs a few months after an exercise program is begun. One’s heart rate reflects the amount of work the heart must do to meet an increase of demands of the body when engaged in activity. Heart Rate tends to increase proportionally with intensity oxygen uptake [16].
