Blood Pressure Lab Report

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

(Marieb and Hoehn, 2010, p 703) defined Blood Pressure (BP) as ‘the force per unit area exerted on a vessel wall by the contained blood, and is expressed in millimetres of mercury (mm Hg)’. BP is still one of the essential and widely used assessment tools in healthcare settings. Nurses generally record the arterial BP which is the forced exerted blood that flows through the arteries, to establish a baseline and to determine any risk factors. BP

In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left

There are four blood types found in humans. These are A blood type which has the genotype either AA or AO, B blood type which has the genotype either BB or BO, AB blood type which has the genotype AB, and O blood type which has the genotype OO. These genotypes show a combination of complete dominance and codominance. A and B traits are dominant to the recessive O trait, however, the A trait is codominant to the B trait. Each blood type codes for certain antigens. A blood codes for the A surface antigen, B blood codes for the B surface antigen, AB blood codes for both the A and B surface antigen, and O blood does not code for a surface antigen. Therefore to determine one’s blood type a test can be performed

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

When checking for orthostatic changes in vital signs the nurse should measure the serial blood pressure and take the pulse of a patient in the supine, sitting, and standing positions. The nurse should first start by placing the patient in the supine position and allowing the patient to rest for 2 to 3 minutes before taking the blood pressure. Next, the nurse should place the patient in the sitting position with their legs dangling off the side of the bed. Then the nurse should allow the patient to rest for 1 to 2 minutes before measuring the blood pressure once again. Lastly, the nurse should reposition the patient to the standing position and should allow 1 to 2 minutes of rest before proceeding to the last blood pressure measurement. Orthostatic changes in the patients pulse and blood pressure need to be monitored closely because they can indicate signs of dehydration concerning the gastrointestinal system. Usually while the patient is in the standing position the systolic blood pressure will decrease 10 mm Hg, and the diastolic blood pressure will increase a bit. Now, when the systolic blood pressure decreases by 20 mm Hg, the diastolic blood pressure decreases by 10 mm Hg or higher, and there could be no change in heart rate or there could be an increase in the heart rate of 20 beats/minute or higher while reposition from the supine position to the

Record this reading as the systolic pressure. You continue to deflate the cuff until the tapping sounds cease.

A summary of 3,246 individuals (identified by ID numbers) with corresponding systolic blood pressures was used as my primary data set.

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

2.1 Introduction The cardiovascular system includes the organs that regulate blood flow through the body mainly the heart and the blood vessels. This system has as basic function to provide a continuous flow of blood to organs and cellular tissues of the body in order to distribute oxygen and nutrients, eliminate waste and carbon dioxide generated during their activity and transport hormones produced by endocrine glands to the receivers. This chapter aims to explain the physiological basis of the cardiac activity and its relation with the autonomic nervous system (ANS), to understand the usage of electrocardiogram (ECG) to detect driver fatigue related directly to the ANS. 2.2 Electrocardiogram (ECG) The electrocardiogram (ECG or EKG)

Physical Examination and Laboratory Test Anthropometric measurements including height and weight were measured while the patients were lightly clothed and without shoes. Measurements were conducted using a calibrated scale, wall-mounted stadiometer, and tape measure. Body mass index (BMI) was calculated using the following formula: weight/height2(kg/m2). Blood pressure (BP) was measured in the right arm with subjects in a sitting position using a regular mercury sphygmomanometer after resting for 15 minutes. Three consecutive blood pressure readings were used to calculate amean BPvalue.

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
