Digital Blood Pressure MachinesA sphygmomanometer or Blood pressure meter also known a BP Monitor, is a device used to measure blood pressure, comprising of an inflatable cuff designed to restrict blood flow when wrapped on the upper arm. A sphygmomanometer or Blood pressure meter also known a BP Monitor, is a device used to measure blood pressure, comprising of
an inflatable cuff designed to restrict blood flow when wrapped on the upper
arm, and a digital or mercurial or mechanical manometer to measure the
pressure, is used in conjunction with the cuff as a means to determine the rate
at which the blood pressure is flowing or just starting, and the pressure it is
flowing unimpeded. Sometimes manual sphygmomanometers are used in conjunction
with a stethoscope. There are three types of Blood Pressure Monitors:
Aneroid Blood Pressure Monitors or Manual blood pressure
monitors – Mostly includes an arm cuff, a squeeze bulb for inflation, a
medical gauge to measure the blood pressure and sometimes a stethoscope. These
monitors are renowned for delivering the best most accurate readings. Digital Blood Pressure Monitors: - Also called Electronic or Automatic blood pressure monitor, available as an Upper Arm Cuff or wrist unit, easy to operate and practical in busy and noisy environments, but Arm Cuff digital monitors are considered the more accurate compared to wrist monitors. They have a display screen which displays results or readings. Commonly, these are now supplied with a single one push button for easy operation. Care must taken though, when using the electronic versions as sometimes they may not give accurate results if the cuff is not wrapped accurately, that is why Doctors take 2-3 readings whenever they use digital monitors.
Digital Semi-Automatic – which are both digital and manual. These give electronic digital readings but are manually inflated by using a bulb inflator, easy to operate as the automatic blood pressure monitors above.
Digital portable finger blood pressure monitors with automatic inflation. These are more portable and easy to operate, although less accurate and used. They are the smallest blood pressure monitors on the market.
Blood pressure (BP) is the pressure exerted by circulating blood upon the walls of blood vessels, and is one of the principal vital signs. During each heartbeat, BP varies between a maximum (systolic) and a minimum (diastolic) pressure. [1] The mean BP, due to pumping by the heart and resistance to flow in blood vessels, decreases as the circulating blood moves away from the heart through arteries. Blood pressure drops most rapidly along the small arteries and arterioles, and continues to decrease as the blood moves through the capillaries and back to the heart through veins. [2] Gravity, valves in veins, and pumping from contraction of skeletal muscles, are some other influences on BP at various places in the body.
The term blood pressure usually refers to the pressure measured at a person's upper arm. It is measured on the inside of an elbow at the brachial artery, which is the upper arm's major blood vessel that carries blood away from the heart. A person's BP is usually expressed in terms of the systolic pressure and diastolic pressure (mmHg), for example 120/80. Ideally all BP Monitors should be operated by a trained person.
