Pulmonary Hypertension Essay

Mr. Dunn's blood pressure reading is 189/110. His LDL cholesterol reading is 200 mg/dl. He asks the student nurse if he should be concerned about his blood pressure.

Pulmonary hypertension is a lung disorder. The arteries that carry blood from the heart to the lungs become narrowed, making it very hard for the blood to get through the vessels, this then causes the pressure in the arteries to increase more than usual (high blood pressure). Scientists think that the procedure starts with injury to the layer of cells that line the small blood vessels of the lungs.

This causes the ventricles to dilate in order to maintain adequate stroke volume. Usually, this will improve over the next 7-10 days.

High blood pressure (hypertension) is a major health condition which affects many Americans. This health condition may increase the risk of cardiovascular disease and stroke. A normal blood pressure consists of systolic blood pressure divided by diastolic blood pressure, 120/80mmHg (millimeters of mercury). High blood pressure is defined as systolic pressure which is greater than 140mm Hg, and diastolic pressure which is over 90mm Hg. Hypertension influences the health outcomes of black Americans more than other races in the United States. Racial discrimination and socioeconomic status are two major factors which influence the rate of high blood pressure in the black American population.

John’s long standing Hypertension causes his heart to work harder, putting more strain on his heart and arteries. In order to achieve a gradient in pressure by which blood flows from an area of higher pressure to one of lower pressure, the left ventricle must exceed the increased pressure in the arterial system (Ref).

et al. 2017). Pulmonary hypertensions occurs in about 8-23% of premature infants (Vyas-Read S et. al. 2017). One method of determine if a patient has pulmonary arterial hypertension is by lung function test (Davis R and Mychaliska G, 2013). One current method used to help treat pulmonary arterial hypertension is assisted ventilation, the method helps lower blood pressure (Davis R and Mychaliska G, 2013). However assisted ventilation can not be used in all preterm infants some extracorporeal life support which will provide respiratory and veno-arterial support (Davis R and Mychaliska G, 2013).

The increased resistance of blood flow through the pulmonary semilunar valve from the right ventricle backs up the pressure of blood

Hypertension is the medical term for high blood pressure. A normal blood pressure is 120/80. A blood pressure reading higher or equal to 140/90 is considered abnormally high. Elevated blood pressure means your heart is working harder than normal, putting both your heart and arteries under great strain. High blood pressure is serious business.

More blood, causing a high force within the Left Ventricle and left atrium. This weight backs up

Emphysema can be contracted by people of all walks of life and does not favor any particular ethnic groups. The contraction of emphysema mainly depends on life style.

Pulmonary hypertension. Shortness of breath and trouble breathing are regular manifestations of this condition, which might be deadly.

Hypertension occurs when there is an increase in cardiac output or total peripheral resistance, or both (McCance, 2015). Cardiac output is increased by an

“Pulmonary arterial hypertension is defined as a sustained elevation of pulmonary arterial pressure to more than 25 mm Hg at rest or to more than 30 mm Hg with exercise, with a mean pulmonary-capillary wedge pressure and left ventricular end-diastolic pressure of less than 15 mm Hg,” (Faber,

The human body is a very complex organism composed of different types of systems and functions. All the functions that each system has, is what makes possible for the body to obtain life. One of the most important systems in one’s body is the circulatory system, where the heart, the lungs, and the blood vessels work together to form the circle part of the circulatory system. The pumping of the heart forces the blood on its journey. The body’s circulatory system really has three parts: pulmonary circulation, coronary circulation, and systemic circulation. Each part must be working independently in order for them to all work together. However, when one of the parts of the circulatory system does not

Emphysema Emphysema is a condition in which there is over-inflation of structures in the lungs known as alveoli or air sacs. This over-inflation results from a breakdown of the walls of the alveoli, which causes a decrease in respiratory function (the way the lungs work) and often, breathlessness. Early symptoms of emphysema include shortness of breath and cough. Emphysema and chronic bronchitis together comprise chronic obstructive pulmonary disease (COPD).
