Gastrointestinal (GI) bleeding can occur when an acute or chronic irritant disrupts the mucosal barrier or when a disease alters the process that maintains the mucosal barrier (LaMone‚ Burke‚ Bauldoff‚ & Gubrud‚ 2015). Gastrointestinal bleeding can happen anywhere along the gastrointestinal tract (Gastrointestinal bleeding‚ 2015). GI bleeding is divided into upper GI bleeding and lower GI bleeding. The upper GI bleeding includes the esophagus‚ stomach‚ and the first part of the small intestine

What are the major differences between gestational hypertension‚ preeclampsia and eclampsia? Pregnancy-induced hypertension is a rise in blood pressure‚ without proteinuria‚ during the second half of pregnancy. Pre-eclampsia is a multisystem disorder‚ unique to pregnancy‚ that is usually associated with raised blood pressure and proteinuria. It rarely presents before 20 weeks’ gestation. Eclampsia is one or more convulsions in association with the syndrome of pre-eclampsia. (Duley‚ L. (2008)

Science Case Study: Coronary Artery Disease (CAD) Introduction: CAD is defined as the impairment of the flow of blood to the myocardium and is a vascular disease but directly impacts cardiac function by reducing oxygenation of cardiac tissue (Porth‚ 2005). Mrs. X has been experiencing episodes of chest pain for the last 18 months and has been diagnosed with stable angina resulting from CAD. She has been admitted to the ward prior to undergoing an off pump coronary artery bypass graft (CABG) of

Showing cardiovascular and ventilatory responses at rest and during exercise Abstract Objective: The objective of this experiment is to analyse how the cardiovascular and respiratory parameters are affected by steady state exercise. Method: The experiment was split into two stages‚ rest and exercise. A spirometer‚ an ECG‚ a Douglas bag and a blood pressure monitor were used at rest on the subject. In the exercise phase a Douglas bag and the blood pressure monitor were used to measure the subject’s

Fluid (ECF) – This is fluid found outside of the cells and the amount of ECF decreases with age. In the newborn for example‚ approximately ½ of the body fluid is contained in the ECF. By the time the infant has reached one year old; the ECF has decreased to approximately 1/3 of the total volume. In an average 70 kg adult the ECF is approximately 15 liters of total volume. ECF can further be divided into the following: * Interstitial Fluid – This is the fluid that surrounds the cells and equals

impacts stroke volume. Although stroke volume is nearly constant‚ temporary stressors influence the heart rate‚ which impacts cardiac output‚ influencing the heart rate and contractility. If there is an increase in stroke volume‚ there is an increase in the cardiac output; the heart may be increased as well. The same rule will apply if there is a decline the cardiac output; there will always be a correlation that varies and relates with stroke volume and the heart rate. Homeostatic is the reason temporary

The Physiology of Fitness Assignment 1 Helpsheet Step 1 You need to introduce your assignment‚ here I would define two key terms for the entire of this assignment these are chronic and acute. Example Answer There are many changes to the body during exercise; these can be classified as acute and chronic. Acute meaning they are short term and happen almost instantly with the onset of exercise. The other chronic is long term and allows the body to adapt its capabilities so therefore it
