Common carotid artery

starts sprinting his heart would pump blood around his body and this would increase progressively whilst he starts running. The systolic blood pressure is the highest pressure in the bloodstream. 2. The diastolic blood pressure is there so that the arteries can resist the blood flow. A sport example of diastolic blood pressure could be marathon runners, the blood flow would be resisted and would stay the same; it only occurs between beats. The diastolic blood pressure is the lowest pressure in…

1. What were the main findings of Mr. Penzey’s physical exam? How could his CT results be related to his blood pressure findings? A physical examination for high blood pressure also comprises a medical history. The extent of the physical examination as well as the level of detail in your doctor's questions depend on how high your blood pressure is in addition to whether you have other risk factors for heart disease. High blood pressure can harm your blood vessels, heart as well as kidneys. This…

later stages where HIV turns into AIDS, your body can develop tumors, infections and central nervous system symptoms. This is caused due to the lymphocyte count being 200 or lower in the body. In this stage the body’s immune system is so weak that a common illness such as pneumonia can be the cause of death. There is no cure for HIV there are only drugs to slow down the…

receptors represent the majority of intracellular Ca²+ channels in cardiomyocytes and arbitrate a process known as Ca²+ induced Ca²+ release. The free Ca²+ binds to the troponin C present on the actin-containing thin filaments of myofibrils. Troponin proteins consists of three different subunits, Troponin T, Troponin I, and Troponin C, with each subunit being responsible for a different part of troponin function. Troponin T is a tropomyosin-binding subunit and hence regulates the interaction of…

Incidence of difficult intubation Difficult tracheal intubation contributes greatly to anaesthesia related morbidity and mortality. The principal adverse outcomes associated with the difficult airway include brain injury, cardiopulmonary arrest, unnecessary tracheostomy, airway trauma, damage to teeth and death8,9 The incidence of failed tracheal intubation ranges from 1 in 1000–2000 cases in the elective setting10,3. Failed and difficult tracheal intubations are associated with…

SUMMARY Airways Turn the victim on to their back and then open the airway using head tilt and chin lift: Place your hand on their forehead and gently tilt their head back. With your fingertips under the point of the victim's chin, lift the chin to open the airway. Airway obstruction is an emergency. Get expert help immediately. Untreated, airway obstruction causes hypoxia and risks damage to the brain, kidneys and heart, cardiac arrest, and death. Look for the signs of airway obstruction: •…

which symptoms come quickly, get rapidly worse, but once treated symptoms go away and don't return. The other reaction type is called bi-phasic, where symptoms start and go away for a period of time, then return with increasing symptoms. The most common causes of anaphylaxis is food allergies, medications, latex exposure, and insect bites/stings. Naturally, the body produces antibodies to help that help us to fight off foreign substances such as bacteria and viruses. On the other hand, some…

The automatic response of the body is to increase cardiovascular output when activity rate increases; in order to raise oxygen levels in the blood for cell respiration. However, this response is varied depending on the type of activity being undertaken by muscles. A higher intensity exercise such as running causes a larger cardiovascular response however in the increase in mean arterial pressure is small. Whereas a lower intensity exercise causes a low cardiovascular response but the increase in…

schedule and the newest addition to his company, and it was clear to see that he had a lot on his plate. I began to think more about how his diagnosis of hemochromatosis would affect his life. For one, I researched hemochromatosis and found fatigue was a common symptom of people with high iron levels (O’Connell & Sheahan, 2011). With his busy schedule, I can imagine that iron imbalance would contribute greatly to fatigue in his life. Also during R.K.’s visit, the nurse asked if he made it in…
