1. PHOTOPLETHYSMOGRAPHY Photoplethysmography (PPG) is a simple and low-cost optical technique that can be used to detect blood volume changes in the microvascular bed of tissue (1). Pulse Photoplethysmography was introduced to the world by Hertzman in the year 1938. It is a noninvasive technique that makes use of light source and a detector. The change in blood volume is synchronous to heart beat and hence this method can indirectly measure heart rate. PPG has been used to assess skin

non-culprit arteries as a part of a multi vessel occlusion disease which confer a substantially increased risk of cardiovascular morbidity and mortality. According to ACC/AHA guidelines for the management of STEMI 2013‚ primary PCI for the culprit artery is the recommended method of revascularization in STEMI. PCI should not be performed in a non-culprit artery at the time of primary PCI in patients with STEMI who are hemo-dynamically stable ( class III (level B)). PCI in a non-culprit artery is only

first part of the 20th century. During those days‚ there were four most commonly used bloodletting methods practiced by doctors. The first was said to be the continued use of leeches. The second was called arteriotomy‚ which is a process where the arteries in the temples would be ruptured and bled. The third was phlebotomy‚ commonly known back then as “breathing a vein”‚ where a large vein would be cut‚ to draw blood. The last was scarification which is said to be a particularly stomach-tossing method

For example having a healthy cardiovascular system helps the blood in the body flow better. "Cardiovascular exercise reduces the amount of plaque buildup and maintains the elasticity of your arteries" (What…). Having a strong and healthy cardiovascular system can also prevent diseases and help improve the body’s ability to regulate temperature. There are also many other benefits such as controlled blood pressure and cholesterol which come with

In this assignment the use of Haemodynamic monitoring will be discussed; the author will discuss a patient‚ (Mary) that came to operating theatres for a procedure. Names that are used have been changed in accordance with the Nursing and Midwifery Council (2004)‚ to protect identities. The specific haemodynamic monitoring used for the patient is‚ Direct Arterial Pressure Measurement‚ more commonly termed “A line”. Mary is a 68 year old female who came to theatres for a diagnostic laparotomy

lining of arteries forming plaque. Atherosclerosis typically begins in early adolescene and progresses with age.To date‚ the exact cause of atherosclerosis still remains unknown. However‚ there are several risk factors include age‚ gender‚ racial factors‚ family history‚ high blood pressure‚ high cholesterol‚ tobacco smoke‚ diabetes‚ obesity and physical inactivity that increase the chances of developing atherosclerosis.

The cause has not been determined. It may be an autoimmune disorder. The disorder affects the mucus membranes‚ lymph nodes‚ walls of the blood vessels‚ and the heart. Kawasaki disease can cause inflammation of blood vessels in the arteries‚ especially the coronary arteries. This inflammation can lead to aneurysms. An aneurysm can lead to a heart attack‚ even in young children‚ although this is rare. Symptoms Kawasaki disease often begins with a high and persistent fever greater than 102 °F‚ often

the force against the walls of your arteries as your heart pumps blood through your body. Blood pressure readings are usually given as two numbers -- for example‚ 120 over 80 (written as 120/80 mmHg). One or both of these numbers can be too high. The top number is called the systolic blood pressure‚ which is the force of blood in the arteries as the heart beats‚ and the bottom number is called the diastolic blood pressure which is the force of blood in the arteries as the heart relaxes between beats
