Blood pressure is the pressure exert in the circulatory system, often measure to diagnose the effective contraction of the heart and the elasticity of the arterial walls. It is measure and share in two readings.
The upper reading denotes the systolic pressure, which reflects the left ventricular contraction, and the lower reading denotes the diastolic pressure, which reflects the peripheral arterial wall resistance.
How to measure the blood pressure?
The standard equipment use to measure blood pressure is call as a mercury sphygmomanometer.
The ban on the use of mercury has put this gold standard instrument out of its role, and many devices without mercury columns have been introduce.
Method use to check the blood pressure.
The sphygmomanometer cuff is tied around the arm and then rested at the level of the heart on a table.
The person checking the blood pressure usually talks to the patient to make them comfortable and then proceeds to check the pulse by palpating the wrist over the outer aspect to feel the radial artery.
Once the pulse is locate and felt, the pressure in the cuff is inflated to occlude the brachial artery to a level where the radial pulse at the wrist is not felt.
The stethoscope is shift over the front of the elbow, slightly towards the inner side, and the pressure is slowly release.
The point at which the sound of the bounding pulse is hear is note as the systolic pressure.
It is release further to a point when the sound of the bounding pulse muffles and vanishes.
This point is consider as the diastolic pressure.
So, measuring methodically through palpatory and auscultatory method is important.
This method ensures that the cuff is not unduly inflate, and the palpatory technique gives time for the person to relax.
How often does blood pressure need to be monitor?
Present devices, which are not mercury manometers, give the reading either manually or digitally.
It is always important to check blood pressure while sitting and lying.
If a patient is detect to have a high range in blood pressure, then the blood pressure needs to be check twice a day, preferably in the morning when they wake up and in the evening for 5-7 days.
Hypertension is when the force of the blood against the artery walls is higher than usual.
It is commonly define as blood pressure above 140 /90mm Hg.
A person diagnose with high blood pressure needs to be closely monitor in the initial days of medication and then requires regular follow-ups.
Measures taken around recording blood pressure.
Most wearable devices are design in such a way that it reads the heart rate and blood pressure while doing day-to-day activities.
They are also tag with a signalling system to indicate deviations from the normal range.
Even though these devices provide correct readings, it is better to cross-check the readings with regular monitors.
Common myths around high blood pressure.
Once the blood pressure reaches normal, one need not take the medicine.
It is always important to check and modify lifestyle habits wherever possible and required before starting the medication to control high blood pressure.
A rise in blood pressure does not cause any symptoms.
High blood pressure is known to be a silent killer and one of the primary causes of cardio and cerebrovascular disorder.
So, strict discipline in regulating lifestyle and close follow-up to check blood pressure regularly can avoid sudden cardiac deaths and cerebral stroke.
