systolic blood pressure measured in the auscultatory method is more accurate than that measured in the palpitation method because the palpitation method is prone to more human errors such as how strong the pulse is‚ where it is located‚ how hard the wrist is pressed during palpitation and a stethoscope which is used in the auscultatory method is more sensitive than feeling a pulse. Hearing the pulse involves less human error than feeling it. 2. The maximum pressure exerted when blood is ejected

Introduction: High blood pressure or hypertension meaning high pressure (tension) in the arteries. Arteries are vessels that carry blood from the pumping heart to all the tissues and organs of the body. Normal Blood Pressure is below 120/80; blood pressure between 120/80 and 139/89 is consider pre-hypertension‚ and a blood pressure of 140/90 or above is considered high. The systolic blood pressure is the pressure in the arteries as the heart contracts and pumps blood forward into the arteries

10/7/12 Blood Doping Blood doping is the altering of the number of RBC’s (red blood cells) to increase the flow of oxygen by a series of techniques. Mostly used by athletes. The most common way is taking out about two pints of the athlete’s blood a few weeks before the competition they are competing in. The blood is frozen until a couple days before it is needed‚ thawed out‚ and then injected back into the athlete. This method is known as autologous doping (transfusion of blood from same person)

Issue study - blood doping Blood doping is generally known for the increased of hemoglobin throughout the bloodstream. This basically means that there is more oxygen carrying protein in the blood. Blood doping has three different types‚ Injections of Erythropoietin (EPO)‚ Blood transfusions and injections of synesthetic oxygen carriers. The athletes who blood dope are usually the ones who compete in endurance and long distance events. Competitors who blood dope believe this is best way they can

When blood is removed from a vein‚ it is called venipuncture or phlebotomy. Venipuncture should be performed with care. The veins of a patient are the main source of specimens for testing‚ the entry point of medications‚ and the site for IVs and blood transfusions. Because there are only a limited number of easily accessible veins in a patient‚ it is important that everything be done to preserve their good condition and availability. Universal precautions should be observed at all times. Gloves should
