What is blood pressure?
Blood pressure is to measure blood force against arterial walls when the heart pumps. The pressure is measured in millimeters of mercury (mmhg) and is expressed as two numbers. For example, the optimum blood pressure for an adult is 120 over 80 or 120/80. The highest number, called systolic pressure, measures the highest pressure exerted when the heart contraction is withdrawn. The lower number, called diastolic pressure, shows the minimum pressure on the arteries when the heart lies between rhythms.
Blood pressure is measured with a cuff and a stethoscope, while the arms are in a rest position. The cuff is located about one inch above the bend of the elbow and is inflated until the mercury dial reaches 30 points higher than the usual systolic pressure of the person or 210, unless the previous data is available. The stethoscope is placed on the artery inside the elbow and the air is slowly leaked from the cuff. The point on the sound of pulse is heard for the first time, the systolic pressure number; The point in which the sound disappears is the diastolic number.
Several factors can affect blood pressure, so one high reading does not necessarily mean that a person has hypertension or high blood pressure. Immediate stimuli, such as fear, pain, anger and some medicines, can temporarily increase human blood pressure. If there has been a high reading and one of these factors is present, the person must be repeatedly monitored for some time to see if it is a persistent condition or whether reading was simply based on circumstances.
hypertension is the main cause of strokes, cardiovascular disorders, kidneys, urological and neurological conditions and preeclampsia in pregnant women. Healthy pressure reading of 120 over 80 or lower is considered healthy. If the systolic number is above 120 to 139 or the average instant number is above 80 to 89, it is considered before hypertension. Systolic values from 140 to 159 or diastolic values from 90 to 99 are classified as phase 1 hypertension. Systolic measurements160 or higher or diastolic measurements 100 or higher indicate a serious condition of phase 2 hypertension.
If the person has been determined to have hypertension, it is necessary to solve the condition. Some lifestyle changes may be useful such as healthy eating, maintaining the right weight, regular exercise and reducing salt and alcohol consumption. In some cases, this effort is not enough and medicines are indicated. Although the patient is on treatment, changes in a healthy lifestyle will help control the condition and can reduce the amount of drugs necessary to maintain healthy reading blood pressure.
Sometimes patients have pressure readings that are less than 90 over 60 years, which is what is considered to be the lower part of the normal range. This condition, called hypotension, must cause nothing but dizziness when it moves quickly from sitting to a permanent position. However, hypotension may indicate basic health, such as heart failure, infection, severe diabetes, shock, gland disorders or dehydration. Alcohol,Anti-sound and antidepressants, diuretics, painkillers and some other medicines may also cause hypotension. Human blood pressure can change over time, so periodic monitoring should be part of everyone's preventive health care.
