Blood pressure is one of the four vital signs of our body. The four vital signs are heart rate, breathing rate, temperature, and fourth is blood pressure. These four signs indicate that everything is fine in our body or not.
Now a days almost one person of every single family suffering from hypertension and hypotension. In this type of patients, they always need to check their blood pressure everyday.
Digital & Manual B.P. Machine Which is batter.
Two types of Blood pressure machines are available in the market, first is Mercury sphygmomanometer with appropriate cuff used for manual method, and second is Digital BP machine which is use to checked blood pressure it is easy to use.
But as we are medical professionals, we mainly preferred blood pressure should be checked by manual BP machine. Blood pressure with manual BP machine checked in a better way and it’s readings are also considered more accurate.
That’s why I thought why not teach everyone to check blood pressure through this article today.
B.P. Machine and it’s Part
Blood pressure machine also know as (in medicine line) sphygmomanometer.
1- Rubber Pump or inflation bulb is a hand pump that was used to pump air into the ‘inflatable cuff’. Pressure controller connected with Rubber Pump.
2– Inflatable cuff is wrapped around the upper arm and is connected to an apparatus that records pressure.
3- Rubber tube- The BP instrument has two rubber tube. One is attached from Mercury to inflatable cuff another is attached Rubber Pump to inflatable cuff.
4- Manometer. It is used to measure the air pressure in mmHg.
5-Valve. It is use as a deflation valve to control the cuff. Play a vital role in getting an accurate measurement.
6-Scale or Gauge- This the scale where the reading is appear of the blood pressure.
A blood pressure reading includes two numbers that indicate the pressure inside the arteries as the blood flows through the body.
Procedure to check blood pressure
Preferred procedure of Blood pressure should be measured after a period of adequate rest (3-5 min), twice on each occasion in the right arm in seated position.
Raise your arm to heart level. Elevate your arm so that when you bend your elbow, your elbow is parallel to your heart. You can check you blood pressure on both arm.
1-Wrap the cuff around the upper arm. We have to tie the cuff one to two inches above the cubital fossa. (The cubital fossa is a triangular-shaped depression over the anterior aspect of the elbow joint).Make sure the cuff is snug, but not too tight.
Don’t place the cuff over clothing.
2- Firstly you have to place your index finger and middle finger on brachial artery and feel puls if you feel puls then place the stethoscope is over the brachial artery pulse, below the bottom edge of the cuff.
3- Close the airflow valve on the bulb by turning the screw clockwise. Inflate (air into the cuff) the cuff by squeezing the bulb with your right hand.
4- Keep inflating the cuff Keep pumping until the needle on the gauge reaches around 180mmHg. Above your expected systolic pressure.
5-Keeping your eyes on the gauge, slowly release the pressure in the cuff by opening the airflow valve anticlockwise.
6-Listen carefully for the first pulse beat. As soon as you hear it, note the reading on the gauge.
This reading is your systolic pressure (the force of the blood against the artery walls as your heart beats). It is the higher number of the two blood pressure readings.
when blood pressure is written down, it appears at the top.
The clinical name for the puls sounds your hear is “Korotkoff sounds.”That is called upper blood pressure.
Continue to slowly deflate the cuff.
7-Listen carefully until the sound disappears. As soon as you can no longer hear your pulse, note the reading on the gauge.
This reading is your diastolic pressure. (pressure in your arteries when your heart rests between beats).
It is the lower number of the two blood pressure readings, and when blood pressure is written down, it appears at the bottom.
What is Blood pressure readings means?
Once you have recorded blood pressure, it is important to know about reading means
Normal blood pressure: Systolic blood pressure should be 120mmHg and diastolic blood pressure should be 80 mmHg. If your blood pressure is 125/85mmHg doesn’t mean your blood pressure is High there is no specific range in medical field.
Stage 1 Hypertension: Systolic number between 140mmHg and 159mmHg, diastolic number between 90mmHg and 99mmHg.
Stage 2 Hypertension: Systolic number higher than 160mmHg and diastolic number higher than 100mmHg.
Hypertensive Crisis: Systolic number higher than 180mmHg and diastolic number higher than 110mmHg. mmHg(milimeter of Mercury) is the Unit of Blood pressure measurement
