Monitoring the blood pressure (Bp) is the simplest way of determining if the pressure of the blood is too low or too high. In general, blood pressure is the term used to explain the potency of the heart with which it tries to push blood on the sides of the arteries the way it is pumped around the body. There are several types of blood pressure monitoring testing devices available these days, which are portable enough to carry around and is very helpful at times of emergencies. The BP monitors indicate two things, whether an individual has high blood pressure, i.e., hypertension, or low blood pressure, i.e., hypotension. Hypertension can put immense stress on the organs and arteries, which as a result increases the risk of acquiring grave problems such as strokes and heart attacks. Whereas, hypotension is generally not a very serious condition; however, it does cause fainting and dizziness in certain people.
Interpreting the blood pressure reading – A blood pressure is measured in millimeters of mercury (mmHg) and is rendered in two figures such as:
- Systolic pressure – the upper reading, meaning the pressure of the heart when it pushes out blood
- Diastolic pressure – the lower reading, meaning the pressure of the heart while resting between beats
Now, for instance, if an individual’s blood pressure is 140/90 mmHg or 140 over 90, it simply means that the systolic pressure in 140 and diastolic pressure is 90.
Based on a BP monitoring testing market, the product is segmented into the following segments:
Sphygmomanometers – consists of a measuring unit and an inflatable rubber cuff which is applied to the patient’s arm. The cuff is connected to a specific mercury column allowing the finding of systolic and diastolic BP by increasing and slowly releasing the pressure built inside the cuff.
Ambulatory blood pressure monitors – ABPM is measuring the blood pressure when a person is moving around, and leading a daily routine life. It comprises of a small digital blood pressure machine which is attached to a belt around a person’s body and the cuff is connected and circles the upper arm.
Blood pressure transducers – these are used while monitoring a patient’s blood pressure in an invasive procedure. The transducers help in noting down the accurate readings as compared to the rest of the methods.
An approximate guide of BP readings:
- Normal blood pressure is measured between 90/60mmHg and 120/80mmHg
- High blood pressure is considered to be 140/90mmHg or more
- Low blood pressure is considered to be 90/60mmHg or less
