Blood pressure is the first step in the assessment of your health status. Whenever you fall sick or visit a clinician, the first thing that your doctor would do is check your blood pressure. So what is the deal with this blood pressure and why is it so important.
Blood pressure is a potential indicator for any and possibly all dysfunctions going on inside your body. And as the saying goes, it is important to understand normal, in order to know what is abnormal.
When blood flows through the blood vessels, it exerts a certain amount of pressure on their walls. The blood vessel walls too provide some resistance to this pressure. Blood pressure, therefore, is pressure exerted by circulating blood against vessel walls.
The device used to measure blood pressure is called a Sphygmomanometer or a Blood Pressure Apparatus or Blood Pressure Monitor.
Blood pressure cannot be measured without a blood pressure apparatus. A lot of varieties of blood pressure apparatuses are available for use – right from mercury based units to digital ones.
Blood pressure is measured in two gradients – Systolic and Diastolic. Standard unit used to express blood pressure readings is millimeters of mercury (mm of Hg).
Standard Blood Pressure Values and What Do They Mean
Classification | Systolic (mm of Hg) | Diastolic (mm of Hg) |
Normal | <120 | <80 |
Pre-hypertensive | 120-129 | <80 |
Stage-I hypertension | 130-139 | 80-89 |
Stage-II hypertension | 140 or more | 90 or more |
Stage-III hypertension or hypertension crisis | Higher than 180 | Higher than 120 |
Blood pressure can be measured at anytime. It needs to be measured when the patient is unwell. Serial assessment should be done at a regular basis.
Blood pressure can be measured either by Palpation Method or Auscultation. Steps to measure blood pressure are:
Mercury or Aneroid Blood Pressure Apparatus is the most suitable variety to measure blood pressure using auscultation. A trained practitioner will be able to operate these better.
Aneroid and Mercury Blood Pressure monitors have a similar method of function. However, aneroid is free from mercury. Therefore the risk of mercury spillage can be avoided completely.
It should be understood that when attempting to measure blood pressure using palpation method, only systolic reading can be obtained. It is not possible to measure the diastolic blood pressure using this method.
Given to the high prevalence of hypertension, blood pressure apparatus has become an essential instrument for any household. For use at home, a digital, automatic blood pressure apparatus is the best option.
Due to its ease of use, the automatic blood pressure monitor is widely used at home. It is the best kind of device even for elderly patients to measure their own blood pressure at home.
Although, an automatic device is easier to use and without the risk of mercury spillage, calibration at frequent intervals is mandatory to get accurate readings.
Any measurement below the normal levels is considered Low Blood Pressure or Hypotension. Some individuals normally have blood pressure reading below the standard 120/80 mm of Hg. Low blood pressure is a sign of some underlying condition and not a disease itself.

Low blood pressure generally indicates some severe dysfunction going on inside the body. Management of hypotension primarily aims at correction of the causative factor. Some ways to manage low blood pressure are:
According to recent statistical data, about 33% urban and 25% rural Indian population is hypertensive. Out of these individuals, about 25% or rural and an alarming 42% urban population were unaware of their hypertensive status. Males have found to be more affected than females.
According to researches, hypertension is responsible for about 54% of stokes and 24% of coronary heart diseases. In addition to that, risk of hypertension increases two folds in smokers as compared to non-smokers.

All these ways to manage high blood pressure need to go hand-in-hand with actual medical treatment. None of these methods should be used to replace medications. The reason being, constantly high blood pressure can potentially damage vital organs and cause aneurysms and even bleeding at some sites.
Blood pressure apparatuses are almost considered to be a necessity at a clinic, hospital or even at homes. Since high or low blood pressure do not always present with any significant symptoms, blood pressure needs to be checked regularly especially when a person is unwell. Reason being, even in absence of any symptoms, blood pressure indicates health status of a person.
