Arteries of the head and neck

Q-1. Describe the function of hemoglobin in blood and describe how pH can affect the function of hemoglobin and the amount of oxygen in blood. Be sure to relate the lab results you obtained to this discussion. Hemoglobin’s main function is to carry oxygen throughout the human body. As the oxygen molecule is dissolved in the blood it combines with hemoglobin forming oxyhemoglobin. Oxygen released from oxyhemoglobin increases as the blood pH levels decreases. Deoxyhemoglobin can also bind to the…

This case study was performed remembering the ultimate objective to support and appreciate the unmistakable characteristics of CVA and its signs and symptoms. The focus of this case study will be on hemorrhagic strokes. A cerebrovascular accident (CVA) or stroke is caused by an acute lack of blood supply to part of the cerebrum. There are two major types of stroke: ischemic, in which a blockage (a blood clot) diminishes or ends blood stream, and hemorrhagic, in which bleeding in the brain…

Complications of open surgical tracheostomy and their management-our experience Introduction Tracheostomy is the surgical procedure to create an artificial opening in the trachea to bypass the obstructed airway above it. History reveals that it is an oldest surgical procedure dating back 3600 B.C.E. in Egypt(1). It has under gone numerous modifications during the past millennia. The first elective tracheostomy was done in AD 100 by Asclepiad’s of Bithynia and the described by Galen in AD131(2)…

repetitive, since patient arrived to the lab, it is essential to conduct a brief head-to-toe assessment and verify nothing-by-mouth status. With repetitive questioning, patients may remember different pieces of information. Review all laboratory data and confirm…

that is breathed is to help relieve congestion in the chest. Blood pressure is pressure, which is being pushed against your arteries while your heart is pumping blood. If you are obese the chance that you will have for blood pressure is very likely. Strokes are also caused. These can happened because of plaque build up in your arteries. It can block the oxygen to your head, which causes people to have a stroke. You could also get cancer from being obese. The different cancers you can get are:…

people lined the streets to get a glimpse of the Kennedys. The car turned off Main Street at Dealey Plaza around 12:30 p.m. As it was passing the Texas School Book Depository, gunfire suddenly echoed in the plaza. Bullets struck the president's neck and head and he fell towards Mrs. Kennedy. The…

660-661). It is important to do magnetic resonance imaging (MRI) or computed tomography scan (CT) of the head and neck to assess the blood flow to the brain and locate any thrombus or areas of narrowing. A likely candidate for the cause of the professor’s TIA could be a partially blocked carotid artery caused by atherosclerosis. Atherosclerosis is a hardening or narrowing of the arteries caused by damage to the endothelium, or inner lining, of the vessels which can be attributed to the…

Thoracic outlet syndrome (TOS) was first identified by Sir Ashley Cooper in 1921 and was further evaluated by Rob and Standeven in 1958 (McKenzie). Thoracic outlet syndrome is a nonspecific diagnosis that refers to an array of conditions caused by compression of the neurovascular structures that pass through the thoracic outlet (Nichols). These conditions can be named based on their location of compression or the cause of symptoms (McKenzie). Factors that predispose patients to the development…

temporarily removed to expose the brain and then replaced after surgery. A craniotomy may be performed for many reasons including clipping or reconstructing an aneurysm, extracting blood or blood clots from a leaking vessel, removing abnormal masses of arteries and veins, draining abscess, mending skull fractures, repairing a tear in the lining of the brain (the dura mater), removing damaged or swollen areas caused by traumatic injury or stroke, treating epilepsy, installing devices to treat…
