Mechanical Blood Pressure Monitors47

Introduction

Mechanical blood pressure monitors are devices used to measure blood pressure by listening to the sounds made by the blood flowing through the blood vessels. They consist of a cuff that is placed around the upper arm, a bulb that is squeezed to inflate the cuff, a release valve that is used to gradually release the air from the cuff, and a stethoscope that is used to listen to the blood flow. Mechanical blood pressure monitors are accurate and reliable, and they are often used in clinical settings.

Types of Mechanical Blood Pressure Monitors

There are two main types of mechanical blood pressure monitors: aneroid and mercury. Aneroid monitors use a metal diaphragm to measure the pressure in the cuff, while mercury monitors use a column of mercury to measure the pressure. Aneroid monitors are more portable and less expensive than mercury monitors, but they are also less accurate. Mercury monitors are more accurate, but they are heavier and more fragile.

How to Use a Mechanical Blood Pressure Monitor

To use a mechanical blood pressure monitor, follow these steps:1.

Wrap the cuff around the upper arm, about 1 inch (2.5 cm) above the elbow crease. The arrow on the cuff should be pointing towards the heart.2.

Close the release valve on the bulb. Then, squeeze the bulb until the cuff inflates to about 30 mmHg above the expected systolic blood pressure (the higher number in a blood pressure reading).3.

Open the release valve slowly and listen to the sounds made by the blood flowing through the blood vessels. The first sound you hear is the systolic blood pressure. The last sound you hear is the diastolic blood pressure (the lower number in a blood pressure reading).4.

Record the blood pressure reading.

Advantages of Mechanical Blood Pressure Monitors

Mechanical blood pressure monitors have several advantages, including:*

Accuracy: Mechanical blood pressure monitors are accurate and reliable when used correctly.*

Durability: Mechanical blood pressure monitors are durable and can last for many years.*

Portability: Aneroid blood pressure monitors are portable and easy to carry.*

Affordability: Aneroid blood pressure monitors are less expensive than mercury blood pressure monitors.

Disadvantages of Mechanical Blood Pressure Monitors

Mechanical blood pressure monitors also have some disadvantages, including:*

Difficult to use: Mechanical blood pressure monitors can be difficult to use, especially for people with limited hand strength.*

Requires training: It takes some training to learn how to use a mechanical blood pressure monitor correctly.*

Not as portable as electronic blood pressure monitors: Aneroid blood pressure monitors are not as portable as electronic blood pressure monitors.*

Less accurate than electronic blood pressure monitors: Aneroid blood pressure monitors are less accurate than electronic blood pressure monitors.

Conclusion

Mechanical blood pressure monitors are accurate and reliable devices that can be used to measure blood pressure at home or in a clinical setting. They are affordable and durable, but they can be difficult to use and require some training. Electronic blood pressure monitors are more portable and easier to use, but they are also more expensive and less accurate.
