The Effect Of Blood Pressure On The Body Essay

The importance of manual blood pressure readings are often overlooked, even by experienced healthcare providers. Manual blood pressures closely approximate a person’s direct arterial measurements. However, there have been studies that

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

What supports the diagnosis of chronic renal failure instead of acute renal failure? Give reasons from George’s history; his signs/symptoms.

Throughout the course of everyday life, variability of heart rate is present for each individual. As the college students on the campus of Truman State University go about their day-to-day lives, they too experience the phenomenon of heart rate variability. While resting and using little movement, many students spend a great number of hours each day studying - a period of time when the body requires a smaller cardiac output in relation to times of movement. However, during the course of an academic day, Truman students, like the majority of human beings, are faced with instances under which time is limited, and they must increase work output to get from one destination to another. Additionally, there are instances in which physical activity is required with variation of difficulty within a workload/resistance. Through this understanding, one can see that the heart rate changes throughout the course of each day, and is thus dependent on the intensity of each daily activity. Although every student on Truman State University’s campus has his/her own unique physiological makeup and personal physical fitness level - every individual is impacted by the variability of his or her own heart rate in response to activities of daily life.

THE EFFECT OF PHYSICAL ACTIVITY ON BLOOD PRESSURE Courtney Triplett Bio 211 Lab Mark Fandel March 3rd, 2015 ABSTRACT The purpose of this experiment was to measure the effect one minute of physical activity would have on a subject’s blood pressure. In this experiment, physical activity is defined as stair climbing at a moderate pace. For comparison purposes, standing blood pressure was measured before and after physical activity. One subject was used and three trials were completed and the initial blood pressures were as followed; 94/62 mmHg, 106/74 mmHg, and 102/66 mmHg.

The process of taking blood pressure bilaterally is a way to screen patients for subclavian artery stenosis. Hypertension is an important, preventable contributing risk to cardiovascular disease. 80 million adults in the US have been diagnosed with hypertension. This disease is commonly seen in adults aged 60 years and older. The rationale for taking bilateral blood pressure is that if a blood pressure is checked incorrectly or in an arm that has SCA stenosis but has not been diagnosed can lead to improper management of HTN, leading to cardiovascular risk factors presenting themselves.

Unit D: Human Systems in Biology 20 is one of the main sections that becomes relatable to the Program of Studies (POS) for the Heart Rate and Exercise LabQuest activity. General Outcome #2 focuses on how students will explain the role of the circulatory systems and defense systems in maintaining an internal equilibrium. This further goes into measuring the students level of understanding the concepts of heart rate and the factors that affect it (Alberta Education, p. 41). Heart rate can then branch out into concepts of maximum heart rate, resting heart rate and recovery time. Through the LabQuest experiment, the main affecting factor was exercise and how that relates back to the fitness level of an individual [20-D2.3s]. Other key concepts found in the lab’s analysis questions then dealt with disorders of the heart [20–D2. 2sts]. Students are additionally "conducting investigations into relationships between and among observable variables" through the use of tools to gather information in regards to their heart rates [20–D2.2s]. Through group work activities, they are achieving collaborative work in measuring heart rate and other factors relating to the circulatory system [20-D2.4s]. To analyze and interpret, the POS explicitly states that students have the option in determining, from available data, the relationship between blood pressure and exercise [20–D2.3s a]. For the simulation, predominantly at the high school level, the

Ambulatory blood pressure (ABP) monitoring and ambulatory heart rate recording are regarded as the standard methods for the diagnosis and prediction of cardiovascular disease [1,2]. It has been reported that a non-dipping pattern of heart rate is strongly associated with increased risk of all mortality in epidemiological settings [3,4]. In addition, there are many recent reports on the clinical significance of ambulatory blood pressure. A non-dipping pattern and nocturnal hypertension are associated with increased cardiovascular morbidity and mortality [5]. On this basis, we raised some questions. Are there any relationship between HR dip and BP dip? The non-dipping situation expressed on what kind of patients? What can they predict?

The heart rate increases as activity intensity in the body increases. The cause of this increase in heart rate is due to the working tissues in the body increasing their need for oxygen and nutrients. The heart needs to pump faster to supply the tissues with an adequate amount of oxygen and nutrients needed for the muscles (Tortora & Derrickson, 2014, p. 716). During the increase of activity levels in the body and rise of heart rate, blood pressure is additionally effected because of the increased need of oxygen flow to tissues in use and cardiac output directly affects blood flow (Tortora & Derrickson, 2014, p. 741). Therefore the main focus of this report will be discussing the two main concepts of the effects of increased intensity of exercise on heart rate and blood pressure.

Average male data regarding systolic blood pressure indicated that as power output increased, systolic BP increased in a relatively linear fashion. Regarding 4th stage diastolic blood pressure, as power output increased, 4th stage diastolic BP stayed fairly stable and then had a spiked increase around the final/highest power output completed. Regarding 5th stage diastolic blood pressure, as the power output increased, these values also stayed fairly stable with a little increased around the final/highest power output completed. Pulse pressure also had a linear increase in response to an increased power output due to the increase in systolic blood pressure. Finally, heart rate increased linearly with increasing power output until individuals approached maximum in which case it began to plateau.

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.

The literature on the effects of exercise of cardiac output maintains the idea that exercise should affect cardiac output- pulse rate, systolic blood pressure, diastolic blood pressure, QRS-pulse lag, P-T and T-P intervals, because of increased heart rate. For our experiment, we tested this theory by measuring our cardiac output before and after some rigorous exercise. We measured the individual cardiac output and then combined the data to compose a class-wide data average. We compared the results of the experiment to what we expected, which was that exercise does affect our heart. Our data from this experiment supported the notion that exercise does, in fact, change cardiac output.

To start off the experiment, a baseline was needed in order to be able to compare the different variables through out the experiment. The subject was instructed to sit and relax quietly while the blood pressure cuff and pulse plethysmograph were placed properly. After the blood pressure was taken and analyzed, it was found that the subject’s blood pressure was 122/64 mm Hg and a pulse rate of 60 bpm. Now that the baseline was obtained, continuing with the changing variables could take place. Starting with the variable of postural changes, the subject first reclined for three minutes. After the two minutes, the

We decided to measure the subject’s pulse and respiratory rates whilst sitting down because there would be no additional stress on their heart, which would increase their heart rate. Their heart rate should also return to its resting heart rate due to the decrease of muscle use.

Hypertension is defined a consistent elevation of the systolic blood pressure above 140mmHg, a diastolic pressure above 90mmHg or a report of taking antihypertensive medication. Early diagnosis and effective management of hypertension is essential because it is a major modifiable risk factor to cerebrovascular, cardiac, vascular, and renal diseases. The higher the blood pressure, the greater the risk for heart attack, heart failure, stroke, and kidney disease.
