Blood+Pressure

Blood Pressure is the pressure that is put on the artery walls by circulating blood. blood pressure varies between systolic and diastolic pressures. Systolic pressure is peak pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are contracting. Diastolic pressure is minimum pressure in the arteries, which occurs near the end of the cardiac cycle when the ventricles are filled with blood. One's blood pressure is not constant, it changes during the course of the day during activities and rest. Blood pressure is displayed as the systolic over the diastolic. For example the average blood pressure is 120 over 80.To find your blood pressure is very simple there are electronic and manual ways to find one's pressure. A cuff of appropriate size is fitted and inflated manually by repeatedly squeezing a rubber bulb until the artery stops blood flow. Listening with a stethoscope to the brachial artery (artery near the elbow),the examiner slowly releases the pressure in the cuff. When blood just starts to flow in the artery, there will be a whooshing sound heard through the stethoscope the pressure at which this sound is first heard is the systolic blood pressure (upper). The cuff pressure is further released until no sound can be heard the pressure where the last sound is heard is the diastolic blood pressure (lower). In the electronic version all this is controlled by a computer, but the process is the same. Monitoring your blood pressure is very important because it can tell you important information on how healthy your circulatory system is. Discovering that you have high or low blood pressure has been know to be able to detect heart and other health problems. Many things can cause changes in blood pressure such as hyper tension, atherosclerosis, eating habits, blood disease etc. There are ways of controlling you blood pressure some are having a well balanced diet, regular exercise, relaxation, the use of statins. Blood pressure is normally one of the first things a doctor examines on a patient because of the importance of this data.
