Question 1: Hemodynamic changes resulting from trauma-associated bleeding
Answer: Hemodynamics is an essential part of cardiovascular physiology dealing with the forces that govern the blood flow in various segments of the cardiovascular system (Wade, 2013). The pumping action of the heart makes pulsatile blood flow, which flows into the arteries, through the micro-circulation and finally, returns via the venous system to the heart. In the course of each heartbeat, systemic arterial blood force varies among a systolic and diastolic pressure. Blood flow ensures the transportation of nutrients, hormones, metabolic wastes, O2 and CO2 all over the body (Wade, 2013). These sustain cell-level metabolic rate, the regulation of the pH, osmotic pressure …show more content…

T in excellent physical and cardiovascular shape might have more definite compensatory mechanisms before experiencing cardiovascular failure. This patient could appear misleadingly stable, with minimal imbalances in vital signs, while having deprived peripheral perfusion. If Mr. T is an elderly patient or with chronic medical conditions possibly will have a reduced amount of tolerance to blood loss, and less capacity to compensate. Mr. T needs to take medications such as beta blockers that can blunt the cardiovascular reaction. Caution should be used in the value of Mr. T life.
Symptoms of Hypoxia
Hypoxia Symptoms include increases in heart rate, myocardial contractility, and cardiac output (Mandal, 2015). As the heart pumps blood to increase the output of circulating oxygenated blood. These may decrease the amount of blood supplied to the peripheral tissues, leading to a bluish discoloration or cyanosis in these areas (Mandal, 2015). These guards oxygenated blood to the other vital organs such as the brain and the heart (Mandal, 2015). If hypoxia is serious, he might experience extreme pain, or his tissue might become gangrenous

Oxygen is one of the substance that the blood carried, and the heart muscle needs it for survival without it the heart did not function, and it cause ischemia. The discomfort of the woman speaks out against indigestion is an ischemic myocardium that irritates myocardial nerve fibers. These sympathetic efferent fibers enter the spinal cord from levels C3 to T4 accounting for the variety of location of angina pains of the body (McCance, Kathryn, Huether, 2014). Rest and nitrates will stop the pain. Inability to relief indicates an individual may be developing infraction (McCance, Kathryn, Huether,
