Pulmonary artery

Explain the significance of the thickness of the left ventricular wall. The right ventricle wall is small and thin containing deoxygenated blood. The left is just the opposite. The left ventricle is larger and thicker making it stronger than the right, but containing oxygenated blood. However, since it is pumping blood all around the body, it is at a more forceful rate (Oxford Journals, 2016). The major coronary vessels are on the surface of the heart. What is the advantage of that location?…

Introduction The purpose of this lab was so asses our subject’s cardiorespiratory fitness and evaluate their aerobic capacity and also put them into a classification. Methods Take the subject’s the height, weight, body composition and resting heart rate and blood pressure. Then place the HR Monitor on the subject. Explain to the subject the rest and explain the RPE chart and communication methods. Allow the subject to warm up on the treadmill at a low intensity and stretch if they need to.…

of 115 beats/min, respiratory rate 22 breaths/min, blood pressure of 82/40 mmHg, and oxygen saturation of 88% on 2L nasal cannula. A vasopressor is needed to address this patient’s hypotension. Prior to placement of an arterial line at the radial artery, which of the following describes the most appropriate diagnostic test? A. Instruct the patient to flex the elbow to 90 degrees while the physician shakes hands with the patient. The patient is then asked to supinate and the physician provides…

What is Cardiac Catheterization? It is a procedure to examine how well your heart is working. A cardiologist places a thin, hollow tube (sheath) into an artery that leads to the patient’s heart. This will allow guide wires and catheters to be used. A contrast dye is injected through the catheter that can be seen on x-rays. This shows how the blood is flowing to the heart and any blockages or deformities. During the catheterization, the physician can attempt stent or balloon any narrowings that…

Coronary artery Disease (CAD) is when there is build up of plaque within the arteries of the heart. Coronary arteries are blood vessels of the heart that pump blood to the outer part of the thick heart muscle wall. If the artery wall of the vessel were damaged, cholesterol would begin to deposit into the damaged wall. The white blood cells would follow after to remove the build up of cholesterol leading to an inflammatory response. Repeated inflammatory responses would lead to blood vessels…

Coronary artery disease is a potentially fatal and serious disease that affects the lives of many people all over the world. This disease is the most common form of cardiovascular disease in the United States. There is a serious financial impact on the population due to the prevalence and the severity of the disease. While there is no current cure to the disease, it is preventable. There currently are ways to treat coronary artery disease through lifestyle changes, pharmacotherapy, and surgery…

Introduction Coronary Heart disease is the expression that defines the blocked or interrupted of the heart's blood supply by a build-up of fatty substances in the coronary arteries. Over time, the walls of the arteries are stuffed with fatty deposits, which is called atherosclerosis and the fatty deposits are called atheroma (BBC 2013). Coronary Heart Disease (CHD) is a major killer in the UK as well as worldwide. It’s the cause of more than 73,000 deaths in the UK. Each year around 1 in 10…

Hypothesis: If subjects stretch for three five-minute intervals, then their individual blood pressures will be affected and increase because the movement and use of muscles is also being increased. Results: As shown in Table 1, the blood pressures for each subject varied. Isabella’s blood pressure started out high, with her systolic rates remaining within ten points of each other, and her diastolic rates within 12 points of each other. Her beginning blood pressure was 131/91 and after five…

which a blood clot (thrombus) forms in a vein. This clot can limit blood flow through the vein, causing swelling and pain. Thrombosis can occur in deep veins and superficial (surface) veins, and can occasionally break off and travel to the lungs (pulmonary embolus). Deep vein thrombosis is the most common type of venous thrombosis. Superficial Vein Thrombosis (SVT) — Leg vein clots in the superficial veins (veins near the surface of the skin) can cause pain, tenderness, firmness, and/or redness.…

Staying healthy in America is becoming a serious challenge to most people; cutting down on some fat and going for a weekly physical activities to the gym could make a substantial difference in one’s life. Dieting is so important, considering the amount of carbs and calories the average American consumes each day. In fact, about 1/3 of American adults are overweight or obese, not because they don’t have what they need, but the simple fact that healthy food 10 miles away is less appealing compared…
