Classification of bp apparatus mercurial
What is mercurial BP apparatus?
A Mercurial Sphygmomanometer is a device that measures blood pressure. It is composes of an inflatable rubber cuff, which is wrapped around the arm. A measuring device indicates the cuff’s pressure. A bulb inflates the cuff and a valve releases pressure. A stethoscope is used to listen to arterial blood flow sounds.
What is the classification of sphygmomanometer?
Table 3Classification of blood pressure for adults
| Blood Pressure | SBP | DBP |
|---|---|---|
| Classification | mmHg | mmHg |
| Normal | <120 | and <80 |
| Prehypertension | 120–139 | or 80–89 |
| Stage 1 Hypertension | 140–159 | or 90–99 |
Which type of BP apparatus is mercury free?
Non-mercury sphygmomanometers like aneroid and more recently, digital ones have replaced the use of traditional Mercury instruments in many settings.

How do you use a mercurial sphygmomanometer?
How many types of BP apparatus are there?
three types
There are three types of blood pressure apparatus: the mercury-gravity manometer, the aneroid gauge and electronic devices.
What is the function of sphygmomanometer?
To measure blood pressure, your doctor uses an instrument call a sphygmomanometer, which is more often referred to as a blood pressure cuff. The cuff is wrapped around your upper arm and inflated to stop the flow of blood in your artery.
What is the principle of sphygmomanometer?
All sphygmomanometers rely on the principle that when a cuff containing a hollow rubber air bladder is wrapped around a limb and the cuff is inflated, the pressure in the bladder is equal to the pressure on the artery under the cuff.
How does sphygmomanometer measure blood pressure?
Blood pressure is measured using a sphygmomanometer, or blood pressure monitor. It consists of an inflatable cuff that’s wrapped around your arm, roughly level with your heart, and a monitoring device that measures the cuff’s pressure. The monitor measures two pressures: systolic, and diastolic.
What is mercury sphygmomanometer?
The mercury sphygmomanometer has been the first choice for blood pressure measurement for many decades, a fact symbolised by the use of millimetres of mercury (mmHg) in a mercury column as the universal units for recording blood pressure, whatever the device. There are a number of alternatives.
How do you use the BP mercurial apparatus?
How many types of BP apparatus are there?
three types
There are three types of blood pressure apparatus: the mercury-gravity manometer, the aneroid gauge and electronic devices.
How many types of BP are there?
There are two types of blood pressure: Systolic blood pressure refers to the pressure inside your arteries when your heart is pumping; diastolic pressure is the pressure inside your arteries when your heart is resting between beats.
Why mercury is used in BP machine?
Mercury is the only one which is liquid at room temperature, which makes it easy to work with. A tiny change in temperature can make its volume grow or shrink, so it can easily be read on a scale.
What is the name of BP instrument?
sphygmomanometer
The sphygmometer measures BP by balancing air pressure against the pressure of blood in the artery. The sphygmomanometer consists of an inflatable pressure cuff which is wrapped around the patients upper arm and connected to a mercury type Page 2 manometer or to a pressure gauge.
What is normal BP range?
As a general guide: ideal blood pressure is considered to be between 90/60mmHg and 120/80mmHg. high blood pressure is considered to be 140/90mmHg or higher. low blood pressure is considered to be 90/60mmHg or lower.
Why Hg is used in pressure?
Mercury has high density. Because of this property, when there is a change in pressure the change in height of the mercury in the barometer tube will be very reasonable.
Where is cuff placed?
Place the cuff on your bare upper arm one inch above the bend of your elbow. Make sure the tubing falls over the front center of your arm so that the sensor is correctly placed. Pull the end of the cuff so that it’s evenly tight around your arm.
