Blood pressure test
Blood pressure is measured with a sphygmomanometer. With a manual blood pressure monitor, a cuff is tied around the upper arm and inflated so as to momentarily stop the blood flow. When the air is released, the blood pressure is monitored. At this point, two measurements are taken. Systolic blood pressure is the reading when the heart contracts. Diastolic blood pressure is the reading when the heart relaxes between beats. Blood pressure is measured in millimeters of mercury(mm Hg). Hypertension or high blood pressure sometimes does not manifest in obvious symptoms and work as a silent killer. Electronic or digital blood pressure monitors use a microphone to detect the pulsing of blood through the artery. This monitor gives you a reading of pulse and blood pressure.
Hypertension (High Blood Pressure)
Hypertension is a medical term for abnormally high blood pressure. When the blood pressure readings consistently show elevated readings over a period of time, hypertension is the resultant condition. Normal blood pressures hovers around the range of 120/80 mmHg. Pre-hypertension is a Situation when your blood pressure hovers around 130 for systolic pressure and between 80 and 89 for diastolic pressure. Factors that can affect blood pressure are many - salt content of the body, volume of water in the body and the condition of the kidneys, nervous system and blood vessels.
It is essential not to ignore signs of hypertension - high blood pressure, since it increases the strain on the heart and lead to stroke or heart attack. Secondary hypertension is noticed among 5% of the people. The causes can be linked to kidney disease or adrenal gland disease or even narrowing of the aorta. It is sometimes seen due to use of steroids, contraceptive pills. Hypertension induced by pregnancy or pre-eclampsia is another cause for secondary hypertension among women.
Hypertension is known to run in families and chances of your developing hypertension are high if your close relatives suffer from it. Other causes of hypertension are obesity and excess stress. Those who consume large quantities of alcohol or salt are also at higher risk of getting hypertension.
Symptoms of hypertension
If you are obese, it is necessary to lose weight and make dietary changes. Decrease levels of fat and sodium. A modest restriction of salt may decrease blood pressure. Instead increase the proportion of fiber, fruits and vegetables. Limit your alcohol intake to one or two glasses a day. Introduce exercise into your daily routine to treat hypertension. Regular, moderate aerobic exercise can modestly decrease blood pressure and has many other beneficial effects. Gradual weight loss through modified calorie intake and increased physical activity is a good approach to tackle high blood pressure.
Plethysmograph is a diagnostic tool that is used to measure flow or pressure. Body plethysmography test involves sitting inside an airtight box and breathing to a particular volume. Blood pressure cuffs are placed around your arm and leg. The patient undergoing plethysmography test must remove clothing on arm and leg and refrain from smoking at least half hour prior to the test. The consequent expansion and decompression of the chest volume allows physicians to rule out any blockages in the limbs as it measures systolic blood pressure. Any abnormal readings can be indicative of arterial occlusive disease, vascular disease or blood clots or even deep venous thrombosis. This test is also referred to as arterial plethysmography and is a vital pulmonary function test. Plethysmography is often used to determine bronchial reactions to histamine or metacholine. But this test is not as accurate as arteriography.Tags: #Blood pressure test #Hypertension (High Blood Pressure) #Plethysmography
