Control of high blood pressure is largely responsible for the significant decreases in heart attack and stroke fatalities achieved in the last three decades. The unit of pressure in the si system is the pascal pa defined as a force of one newton per square meter.
How To Measure Blood Pressure
Human body pressure measurement. Blood pressure is one of the vital signs along with respiratory rate heart rate oxygen saturation and body temperature. The thin and conforming sensing mat can measure body pressure distribution with minimal interference of the support surface. If however it is too low fainting is a problem. Design optimization verify comfort. Body pressure measurement system. For almost 20 years design and test engineers have chosen xsensors px and lx sensors to improve the comfort safety reliability and ergonomics of their products.
Pressurethe effect of a force applied to a surfaceis a derived unit obtained from combining base units. Normal resting blood pressure in an adultis approximately 120 millimetres of mercury 16 kpa systolic and 80 millimetres of mercury 11 kpa diastolic abbreviated 12080 mmhg. The conversion between atm pa and torr is as follows. Next to taking a persons temperature and weight measuring blood pressure is the most common of all medical examinations. The bottom number called the diastolic pressure. Pressure in the body.
Both pressures have health implications. Bpms measures the pressure distribution of a human body on support surfaces such as seats mattresses cushions and backrests. A body pressure sensor provides valuable insight into the design performance of surfaces in contact with the human body. 80 89 is stage 1. Joints are especially vulnerable to changes in barometric pressure. Common arterial blood pressure measurements typically produce values of 120 mm hg and 80 mm hg respectively for systolic and diastolic pressures.
Blood pressure is recorded as two numbers and written as a ratio. The human body feels the weight of the air and begins to experience problems with mobility. A normal diastolic blood pressure is lower than 80. Measure map and refine pressures exerted on or by the human body our range of body pressure mapping systems and sensors enable you to accurately and repeatedly quantify pressure exerted on the human body. If you are using pressure sensors to measure the entire body torso seat hands or feet our thin flexible and reliable body pressure measurement system is ideally suited. 1 atm 101325 pa 760 torr.
But even if your diastolic number is lower than 80 you can have elevated blood pressure if the systolic reading is 120 129. When systolic pressure is chronically high the risk of stroke and heart attack is increased. Fluid surrounding the joints becomes inflamed causing almost intolerable levels of pain. The top number called the systolic pressure is the pressure as the heart beats.
