COMPARISON OF BLOOD PRESSURE IN SITTING, STANDING, AND LYING POSITIONS IN KEEPING HOMEOSTATIS

Abstrak

This study aims to determine the ratio of blood in the sitting, standing and lying positions. The research method used is a laboratory experimental research method that uses 3 probands by using stethoscope and sphygmomanometer to calculate the heart rate probandus in a lying, sitting, standing position, after light exercise (running in place ±20 steps) after strenuous exercise (running in place ±50 steps) the heart rate will increase in a sitting position because the heart pumps blood will be harder to resist the force of gravity. This makes blood pressure tend to be stable.

The results showed that menunjukkan based on the results of individual studies on the first probandus, namely probandus 1, when sitting, fitriyanti's blood pressure is hypotensive with a pressure of 120/80MmHg, when she stands, her blood pressure is normal with a pressure of 110/70MmHg and when she lies down, her blood pressure is hypotensive with a pressure of 100/70MmHg. . In the 2nd Probandus, Rizka is 19 years old. When sitting down, Rizka's blood pressure is not normal with a pressure of 100/90MmHg, when she stands up, she has hypotension with a pressure of 100/60MmHg, while lying down, she has hypotension with a blood pressure of 100/70MmHg. In the third proband, sartin, the sex is female, aged 19 years. when sitting, sartin blood is hypotensive with a pressure of 110/80MmHg, when standing, sartin blood is hypotensive with a pressure of 100/70MmHg, and when lying down, the blood pressure of Sartin is hypotensive with a blood pressure of 100/60MmHg. This can happen because the probandus is in a state of dehydration, lack of nutrition and nutrition, or because the probandus is sick/unfit or because of other factors so that his diastolic pressure is low.
