How to use blood pressure Machine/how to use bp machine
With an oscillatory device, a cuff is inflated over the upper arm or wrist. Newer models use “fuzzy logic” to decide how much the cuff needs to be inflated for a person to reach a pressure of about 20 mm Hg above the systolic pressure.
When the cuff is fully inflated to this pressure, there is no blood flow through the artery in this condition. As the cuff is deflated below the systolic pressure, the reducing pressure exerted on the artery allows blood to flow through it and establishes a detectable vibration in the wall of the artery.

When the cuff pressure falls below the patient’s diastolic pressure, blood flows smoothly through the artery in normal pulses, with no vibrations established in the wall.
Vibrations occur at any point where the pressure of the cuff is so high that it has to push the artery wall open for blood to flow through the artery.
The vibrations are transferred from the artery wall, through the air inside the cuff, to a transducer in the monitor which converts this into electrical signals.
These instruments deflate at a rate of about 4 mm Hg per second, making them sometimes slower to use than oscillatory aneroid instruments, but they are more accurate.

How do blood pressure machines work
After turning on the machine, wait a few moments. As the machine begins to measure, remain steady and calm. The cuff will inflate, then slowly deflate so that the machine can take your measurement.
When the reading is complete, the monitor displays your blood pressure and pulse on a digital panel.
How do you use a blood pressure machine at home
To begin the test, place the cuff on the patient’s upper arm about one inch above the bend of the patient’s elbow. Pull the end of the cuff so that it is evenly tightened around the patient’s arm.
You should hold it tight enough that you can only slide two fingers under the top edge of the cuff. Make sure your skin doesn’t pinch when the phlegm rises.
To check your blood pressure at home with a digital blood pressure monitor, all you need to do is:
Slide the blood pressure cuff over your upper arm and secure it so that it sits comfortably about an inch above the crease of your elbow.
If you have an automatic model, simply press the button that inflates the cuff.
The arrhythmia introduces additional vibrations within the artery wall, which presents problems for blood pressure detection regardless of the technique employed.
Older people have less elastic arteries, but even the weakest vibrations can be detected using oscillometric instruments and the right sized cuffs. The bladder should cover 80% of the circumference of the arm within the cuff of the upper arm.
How to measure your blood pressure at home using a home monitor
1.) Place the arm cuff just above your elbow.
2.) Remain calm when the machine reading comes.
3.) Take two or three readings, each about one to two minutes apart.
4.) Keep a record of your measurements.
what is the working principle of BP machine
Oscillatory devices generate a digital readout and work on the principle that blood flowing through an artery between systolic and diastolic pressures causes vibrations in the artery wall that can be detected and transduced into electrical signals.
It is possible or Aneroid Devices that also rely on auscultation Devices that rely on oscillations. Oscillatory devices produce a digital readout and work on the principle that blood flowing through an artery between systolic and diastolic pressures causes vibrations in the artery wall that are detected as electrical signals. and is transduced.
How BP Test Works
For a manual blood pressure measurement, the care provider holds a stethoscope over the major artery in the upper arm (brachial artery) to monitor blood flow. The cuff is inflated with a small hand pump. As the cuff inflates, it squeezes the arm. The flow of blood through the artery stops for a moment.
What can a blood pressure machine detect
Blood pressure is measured using a sphygmomanometer or blood pressure monitor. It consists of an inflatable cuff that is wrapped around your arm, roughly level with your heart, and a monitoring device that measures the pressure of the cuff. The monitor measures two pressures: systolic and diastolic.
What diseases are related to high blood pressure
Uncontrolled high blood pressure can lead to complications including:
a. Heart attack or stroke.
b. Aneurysm.
c. heart stops beating.
d. Weak and narrowed blood vessels in your kidneys.
e. Thickened, narrowed, or torn blood vessels in the eye.
f. metabolic syndrome.
g. Trouble with memory or understanding.
h. Madness.
How many types of BP machine are there
There are 3 types of blood pressure monitors: mercury column, aneroid and digital. The most commonly used for monitoring blood pressure at home are aneroid and digital monitors.

What is the average range of BP/ normal blood pressure
Normal blood pressure for most adults is defined as a systolic pressure of less than 120 and a diastolic pressure of less than 80. Elevated blood pressure is defined as a systolic pressure between 120 and 129 with a diastolic pressure of less than 80.
how much does a BP machine cost
BP Machine Price: Mercury and Digital BP Machine price varies with their approximate rate ranging from Rs 500 to Rs 3000.
Advantages of BP Machine
Home blood pressure monitoring is a useful tool for the clinical management of patients with hypertension. Its major advantages are easy to learn techniques, reproducibility of values, sensitivity of measurements and availability of ideal data.
Disadvantages of BP Machine
- High probability of observer error.
- Noise interference can lead to inaccurate readings.
- Small movements can lead to inaccurate readings.
- Difficult to monitor in infants or young children.
- Mercury can pose a threat to the environment.
- Aneroid loses its accuracy over time
