What is a sphygmomanometer how is it used and when is it used?
sphygmomanometer, instrument for measuring blood pressure. It consists of an inflatable rubber cuff, which is wrapped around the upper arm and is connected to an apparatus that records pressure, usually in terms of the height of a column of mercury or on a dial (an aneroid manometer).
How does your blood pressure work?
What is blood pressure? In the most basic terms, when your heart beats, it pumps blood throughout your body, supplying it with the oxygen and energy it needs. As your blood moves, it pushes against the sides of your blood vessels. The strength of this pushing is what is known as blood pressure.
How do you read blood pressure with a sphygmomanometer?
Some health care workers have difficulty using the bell in the antecubital fossa, so we suggest using the bell or the diaphragm to measure the blood pressure. Rapidly inflate the cuff to 180mmHg. Release air from the cuff at a moderate rate (3mm/sec).
How do you start a sphygmomanometer?
- To begin blood pressure measurement, use a properly sized blood pressure cuff.
- Wrap the cuff around the upper arm with the cuff’s lower edge one inch above the antecubital fossa.
- Lightly press the stethoscope’s bell over the brachial artery just below the cuff’s edge.
- Rapidly inflate the cuff to 180mmHg.
What do you need to know about a sphygmomanometer?
What is sphygmomanometer? A sphygmomanometer is an instrument used to measure blood pressure which is also known as a blood pressure meter or blood pressure gauge or blood pressure monitor.
When did the sphygmomanometer start to monitor blood pressure?
Most sphygmomanometers were mechanical gauges with dial faces during the first half of the 20th century. Since the advent of electronic medical devices, names such as “meter” and “monitor” can also apply, as devices can automatically monitor blood pressure on an ongoing basis.
What does an aneroid sphygmomanometer stand for?
Aneroid sphygmomanometer: Aneroid means “without fluid” and in this instrument, there is no use of mercury. It consists of a stethoscope that is attached to the cuff which is further attached to a dial gauge with tubing.
