Blood Pressure 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

(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

View the right internal jugular vein when measuring jugular venous pressure. With aging, the aorta stiffens, dilates, & elongates, resulting in decreased pulsations on the left side. In addition, use caution when palpating & auscultating the carotid artery. Pressure in the carotid sinus may cause a reflex slowing of the heart rate.

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

A sphygmomanometer was used to measure the blood pressure and heart rate of the subject. First, the basal heart rate and blood pressure for each subject was collected by taking the mean of the data on the left arm from three

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.

Blood pressure is a force applied by blood that push against the arteries. Arteries are blood vessels that send oxygenated blood to the heart and throughout the rest of the body. To calculate blood pressure, use a blood pressure machine which shows the two types of pressures, systolic and diastolic pressure. Systolic pressure happens when the heart is decreasing and diastolic pressure is the pressure the occurs when the heart expands. Systolic pressure is always over diastolic pressure and the average is 120/80 mmHg. (S. Jose, E-12) Blood pressure is measured in mmHg which stands for millimeter of mercury.

The finger plethysmograph is a non-invasive way of detecting arterial pressure. The wave image produced by the plethysmograph is similar in appearance to an arterial blood pressure wave. Although the plethysmograph is not a direct measure of pulse pressure, its wave is created by blood flow, so it can so it still provides information about blood pressure and the circulatory system. The plethysmograph graph provides information related to hypertension and cardiac output (Grote et al., 2003).

The purpose of lab six, is demonstrate how different activities like exercise, postural changes, and cognitive thinking change arterial pressure as well as heart rate. Blood pressure, which is abbreviated as BP is the force that is placed onto vessel walls by the blood that it contains. In healthy individuals, BP should be 120/80 mmHg, but recent research has shown that healthy individuals BP should be lower than 120/80 mmHg. The first number, in this case 120 is known as the systolic number. The systolic number is known as the amount of pressure placed onto the vessel wall by blood during ventricular contraction. When someone is taking another persons blood pressure, this is the first sound that the person will hear. This is because the blood vessel opened up enough to allow blood to begin passing through. The second number, 80 represents the diastolic number. The diastolic number represents when the vessel is relaxing and blood is getting through without any extra force. Also, this number is represented by the last sound an individual hears in their stethoscope. Aside from BP, heart rate also known as pulse rate, is the number of times a persons heart beats in a minute. (Marieb & Hoehn, 2014, pp. 708-710).

We expect to see different patterns of pressure-diameter (dP/dR) relationship with similar trends to those obtained in the ex vivo experiments as a result of dynamic smooth muscle contractile activity during pulse pressure waves. C) THE EXPERIMENTAL CONDITIONS AND PROPOSED EXPERIMENTS 1. Ex vivo isolated system: (Wire myography and pressured myography) The following parameters will be determined in three different conditions, with various reagents being added, in both control and MFS aortic samples ex

Stroke is a leading cause of fatalities worldwide, including New Zealand. Stroke Foundation of New Zealand estimates 2500 stroke-related fatalities occur annually, whereas the statistics worldwide are worse. A major stroke is sudden and mostly fatal, whereas minor stroke symptoms are primarily ignored. Artery blockage (Ischaemic stroke), artery rupture (Haemorrhagic stroke) are two types of strokes in which arterial health and properties play a vital role. Arterial stiffness is one such independent property which can be assessed by Pulse Wave Velocity (PWV). PWV can be measured at a few points where the artery is close to the skin surface, carotid artery in the neck is one of such points. As carotid artery is proximate to heart branching directly

Measurement of carotid femoral pulse-wave velocity (PWV), as a reproducible non-invasive index of large artery elasticity and stiffness, enables assessment of the speed of the pulse wave, which is related to the stiffness of the aorta. Aortic PWV has been demonstrated to be a predictor of cardiovascular events and mortality. It is now recognized as an interesting tool for global cardiovascular risk assessment.
