Pulse Pressure Essay

D. PULSE PRESSURE
INTRODUCTION
The pulse pressure is the difference between the systolic and diastolic pressure. The systolic or top pressure is defined as the amount of pressure exerted on the blood vessels when the ventricle is contract (systole). The pressure is due to the force produced as the blood is ejected contacted with the blood vessel’s wall. On the other hand, the diastolic or bottom pressure is defined as the amount of pressure of the blood vessels when the heart is at rest (diastole).

DISCUSSION
A) Pulse pressure
In simplest words, the pulse pressure can be explained as the amount of pressure when the systolic pressure minus diastolic pressure. The unit is in mmHg. As per theory, the pulse pressure is proportional to stroke volume, or the total amount of the blood ejected by the left ventricle

During exercise, the heart works very hard to supply more oxygen to the body. In return, the cardiac output is higher and eventually it will increase the pulse pressure. But in some cases, there’s a condition where the pulse pressure is high even at rest condition. In this case, something is not right with the heart condition. This condition may be due to the stiffness of the major arteries. An example is atherosclerosis (hardening of blood vessel’s wall).

CONCLUSION
The major determinant of the pulse pressure is the aortic compliance and also the stroke volume. The aortic compliance is the ability of the aorta to expand once the blood is ejected to the aorta by the ventricle. The more compliant the aorta, the smaller the pressure change during the ventricular ejection/contraction/systole. Therefore, the smaller the pulse pressure. The wide or high pulse pressure is having a risk of heart disease. The person that having an elevated pulse pressure must seeks for a medical treatment. Among the treatment for high pulse pressure is angiotensin-converting enzyme (ACE)

    Two sides of the heart pump blood through two different circulations. Pulmonary circulation involves movement of blood from the right ventricles to the lungs. Systemic circulation involves movement from the left ventricle, throughout the body. When the heart beats the atria contract first in atrial systole. When the ventricles fill with blood, they too contract together in ventricular systole.…

    This occurs when there is excess fluid in the plural cavity. The plural cavity is the thin, fluid filled space that surrounds the lungs and prevents friction rub and cushion. One of the main causes of pleural effusion is congestive heart failure. This occurs as a result of an increase in pulmonary capillary pressure, which in turn increased the interstitial fluid in the lung. Most often the heart failure that causes pleural effusions are related to right side heart failure, but can also be bilateral failure.…

    Catecholomines will be activated to stabilize the cardiac output. They increase heart rate and PVR, or afterload. The renin-angiotensin-aldosterone-system will increase preload and after load. However, Angiostensin II also facilitates ventricular remodeling which will further perpetuate the problem; this can decrease cardiac contractility and cause ventricular dilation. Insulin resistance can cause extremely detrimental effects on cardiac contractility by decreasing the body’s ability to supply ATP.…

    The aortic valve separates the left ventricle from the aorta while the pulmonary valve divides the right ventricle and pulmonary artery. AV valves and semilunar valves perform an important role in the cardiac cycle because they only allow blood flow when pressure gradient is reached. During ventricular filling, the AV valve remains open due to atrial pressure being higher then ventricular pressure. Concurrently, the semilunar valves are closed as a result of higher pressure in outflow tract then ventricle. When ventricular pressure surpasses atrial pressure, the AV valves close, indicating the isovolumetric ventricular contraction.…

    (“Arteries, Veins, and Capillaries”) Blood goes through the body in blood vessels called arteries, capillaries and veins. Arteries keep blood flowing away from the heart and throughout the body. The blood that travels through the arteries carries o2 molecules to give to the whole body. Arteries are thicker than any blood vessel in the body because it helps with the high pressures of blood being pumped from the heart. Once the blood traveling through the arteries reach the end of that particular blood vessel, it goes through a smaller blood vessel called the capillaries.…

    In a normal heart operating within the normal range of diastolic pressures, the physiological law predominates: when the ventricle dilates, the increased capacity to generate pressure is more important than the increased wall stress. However, in patients with heart failure, the increased wall stress caused by ventricular dilation adds to the energy cost of cardiac contraction, so that the detrimental effects of increasing ventricular volume can outweigh the beneficial effects. In pathological conditions such as acute myocardial infarction, the ability of the left ventricle to perform cardiac work is significantly impaired because…

    The principle in Venturi piping is based on the Bernoulli’s equation. The different pressure between inside of the venturi meter is created by reducing the cross-sectional area of the flow. This pressure will be converted to energy, as a velocity. We can observe the difference of pressure measured by using a different U-tube manometer (A-D). The pressure difference allows to determine the rate of fluid or discharging flow through the pipe line.…

    Patients on PPV can have a weakened cardiac output based on their chest wall and lung compliance, their airway resistance (Raw) and the airway pressure (Paw). When the airway pressure in the patient increases it also increases intrapleural pressure and it compresses the blood vessels inside the heart causing the central venous pressure (CVP) to rise. When this occurs, the pressure gradient decreases between the systemic veins and the right side of the heart, which decreases the venous return to the right side of the heart. It also decreases preload or right ventricular filling. In effect, the right ventricular stroke volume…

    This causes them to signal an area in the brain called the nucleus tractus solitaris. This functions in decreasing sympathetic output to the blood vessels and decreasing blood pressure. In a person suffering from hypertension constantly their baroreceptor may adjust to that constant raise in blood pressure and accept it as its new set point. So now when a persons blood pressure is above the new set point it will want to adjust back to it instead of a normal blood pressure. On a cellular level there are many different causes of hypertension.…
