Artery

High blood pressure, or hypertension, is a condition in which the force of the blood against the artery walls is high enough that it can eventually cause health problems. When the heart beats, is crates pressure that pushes blood through the arteries. Blood pressure is the result of this “push”, or force. There are two forces; one occurs when the blood pumps out of the heart and into the arteries and the second occurs as the heart rests between beats. These two forces each represent the numbers…

Marilyn Monroe once sang, “Diamonds are a girl’s best friend.” This lyric about girls and their diamonds makes sense for obvious reasons. Diamonds are shiny, make women feel like princesses, and are a symbol of “love”. However, diamonds have an intimidating competitor, chocolate. No matter how big the “rock” is, some women would prefer delicious, melt in your mouth, chocolate. Their wise decision could potentially have some great upsides to it. For instance, dark chocolate has numerous health…

atherosclerosis, the main contributor to MI. “Atherosclerosis a common disorder characterized by yellowish plaques of cholesterol, other lipids, and cellular debris in the inner layers of the walls of arteries (Mosby, 2013, pg.153).” Fatty deposits (lipids) are circulating through the blood and become stuck to the artery walls, due to an injury in the endothelial lining of the blood vessel. After some time, the build up of plaque activates the body’s inflammatory process. Macrophages are…

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…

happens when a part of the brain dies because of either clotting or rupture of blood vessels. Stroke is one of the leading causes of death and disability in the world. Strokes can happen when: An artery is blocked due to blood clotting where a part of brain goes without blood for few minutes. An artery ruptures and starts bleeding into the brain How do strokes affect people? — The effects of a stroke depend on ●Which part and how much of the brain is affected ●How quickly the stroke is…

Cerebrovascular accident (CVA) is also known as stroke for short. A stroke is a disease that does not allow the arteries to carry oxygen to the brain. They are the fifth top causes of casualty in America. Knowing the signs and symptoms of a stroke and seeking medical attention may decrease the risk of death. There are a few diverse types of strokes, Transient ischemic attack, hemorrhagic stroke, and ischemic strokes. The first one is transient ischemic attack also known as TIA; it is a clot…

one's arteries, the blood vessels that carry oxygen and other nutrients from one's heart to the rest of their body, become thick and stiff; resulting in the occasional restriction of blood flow to their organs and tissues. Symptoms normally do not appear if it is a mild case. A moderate to severe case has different symptoms depending on where the affected arteries are located. When located in the heart arteries one might experience chest pains or chest pressure, but if it is in the arteries…

Ancient Egyptian mummies from the BC era were found to have had traces of heart disease, particularly with the presence of atherosclerosis or the narrowing of arteries. Grecian and Roman societies also show proof of cardiovascular disease’ ancient presence- they often recognized it by the chest ache so characteristic that precedes a heart attack. [3] Historically, however, the rising occurrences of heart disease…

pressure 15 cmH2O, FiO2 0.4-0.6, fresh gas flow 1-1.5 L/min. Normocapnia was maintained throughout the surgery. CVP remained stable at 16-22 mmHg. Surgery included diagnostic cerebral arteriography with coil embolization of left posterior communicating artery aneurysm, and placement of right external ventricular drain (EVD). The estimated blood loss during the procedure was minimal (less than 50 ml), and the total intraoperative fluid intake was 500 ml of crystalloids. The patient remained…
