Parts of BP Apparatus Names in English with Their Functions

A BP apparatus is a tool to check blood pressure. It has a cuff for your arm, a pump, and a gauge. There are manual ones with a dial and automatic ones. To use, the cuff is pumped up, then slowly let down while checking for heart sounds. The numbers recorded tell if your blood pressure is okay or needs attention. It’s crucial for heart health and used by doctors or at home to stay healthy.

What is PB Apparatus?

A “BP apparatus” is a tool that checks blood pressure. It usually has a cuff you put on your arm, a pump to inflate the cuff, and a display showing the pressure. This helps measure how well your heart is working. It’s used by doctors and at home to keep track of your health.

Types of BP Apparatus

There are several types of blood pressure (BP) apparatus, each with its own features and applications. Here are the main types:

Mercury Sphygmomanometer:

  • Traditional device that uses a column of mercury to measure blood pressure.
  • Consists of a cuff, mercury column, and a bulb for inflation.
  • Requires a stethoscope to listen for Korotkoff sounds.

Aneroid Sphygmomanometer:

  • Similar to the mercury version but uses a dial with a pointer to display blood pressure readings.
  • Portable and doesn’t contain mercury, making it safer for the environment.

Digital (Automatic) Blood Pressure Monitor:

  • Operates electronically and automatically inflates and deflates the cuff.
  • Displays digital readings on a screen.
  • Some models are wrist-based, while others are designed for the upper arm.

Ambulatory Blood Pressure Monitor:

  • Portable device worn by the individual for 24 hours to monitor blood pressure throughout the day.
  • Typically used for more comprehensive, continuous monitoring.

Finger Blood Pressure Monitor:

  • Compact and portable device that measures blood pressure at the fingertip.
  • Generally less accurate than upper arm monitors.

Pediatric Blood Pressure Cuff:

  • Specifically designed for infants and children.
  • Smaller cuff sizes to fit the arms of pediatric patients.

Wall-Mounted Blood Pressure Monitor:

  • Often found in healthcare facilities.
  • Mounted on the wall for easy access and convenience.

Wrist Blood Pressure Monitor:

  • Compact and convenient, worn on the wrist.
  • May be less accurate than upper arm monitors.

Bluetooth-Enabled Blood Pressure Monitor:

  • Connects to smartphones or other devices via Bluetooth for data tracking and analysis.
  • Allows for easy sharing of blood pressure data with healthcare providers.

When choosing a blood pressure apparatus, it’s important to consider factors such as accuracy, ease of use, and the specific needs of the individual or healthcare setting. Additionally, it’s essential to follow the manufacturer’s instructions and healthcare provider’s recommendations for proper use and maintenance.

Use of BP Apparatus

A blood pressure (BP) apparatus with good readability is valuable for accurate and efficient blood pressure monitoring. Its use is straightforward and involves the following steps:


  • Ensure the individual is in a relaxed position, preferably seated with their arm at heart level.
  • Choose the appropriate cuff size for accurate measurements.

Application of the Cuff:

  • Place the cuff snugly around the upper arm, just above the elbow.

Activation of the Apparatus:

  • If using a digital monitor, press the power button to activate the device.

Automatic Inflation:

  • Allow the apparatus to automatically inflate the cuff. This eliminates the need for manual pumping.

Digital Display:

  • Read the blood pressure measurement displayed on the digital screen. The systolic and diastolic values are often shown clearly.

Record and Interpret:

  • Record the blood pressure values for future reference or share them with healthcare providers.
  • Interpret the readings based on established blood pressure categories.

Automatic Deflation:

  • Digital monitors typically deflate the cuff automatically after measurement.

Turning Off the Apparatus:

  • If using a digital monitor, turn off the device to conserve battery power.

Periodic Calibration Checks:

  • Ensure the apparatus is periodically calibrated, as recommended by the manufacturer, to maintain accuracy.

Data Tracking (if applicable):

  • If the apparatus is equipped with memory or connectivity features, take advantage of data tracking capabilities for long-term monitoring.

A BP apparatus with good readability simplifies the process, making it accessible for individuals to monitor their blood pressure at home. Regular monitoring helps in the early detection of changes and assists in managing cardiovascular health effectively. Always follow the manufacturer’s instructions for proper use, and consult with healthcare professionals for guidance on monitoring frequency and interpretation of readings.

Functions of BP Apparatus

The primary function of a blood pressure (BP) apparatus is to measure and monitor blood pressure, providing crucial information about cardiovascular health. The apparatus, whether manual or digital, performs several key functions:

Clear Display:

  • The primary function is to provide a clear and easy-to-read display of blood pressure measurements. A digital screen with large, well-lit numerals enhances visibility.

User-Friendly Interface:

  • The apparatus should have an intuitive interface, making it easy for users to operate, especially for those monitoring their blood pressure at home.

Digital Readouts:

  • For digital monitors, the apparatus should offer precise digital readouts, eliminating the need for interpreting analog dials or mercury columns.

Automatic Inflation and Deflation:

  • Many modern digital monitors have automatic inflation and deflation features, simplifying the measurement process and ensuring consistent results.

Memory Function:

  • A memory function allows the apparatus to store multiple readings, enabling users to track changes over time. This feature is particularly useful for ongoing monitoring.

Irregular Heartbeat Detection:

  • Some advanced models can detect irregular heartbeats, providing additional information about potential cardiac issues.

One-Touch Operation:

  • A one-touch operation simplifies the measurement process, reducing the likelihood of user error.

Large Cuff Compatibility:

  • Good readability includes ensuring that the apparatus is compatible with various cuff sizes, accommodating users with different arm circumferences.

Visual and Audible Alerts:

  • Visual and audible alerts for high or low blood pressure readings enhance user awareness and prompt appropriate action.

Battery Indicator:

  • A battery indicator ensures that users are aware of the battery status, reducing the chances of interruptions during monitoring.

In summary, a BP apparatus with good readability should prioritize a clear, user-friendly interface, precise digital readouts, and additional features that enhance the overall user experience. These qualities contribute to accurate blood pressure monitoring, facilitating better health management for individuals.

How to Measure Blood Pressure


  • The individual should be seated comfortably, with their arm supported at heart level.
  • The cuff is placed around the upper arm, and the individual should be relaxed and not speaking during the measurement.


  • The cuff is inflated to a pressure higher than the expected systolic pressure.


  • The pressure is then slowly released, and the healthcare provider listens for Korotkoff sounds with a stethoscope in the manual method or the automatic monitor detects the blood flow.


  • The systolic and diastolic pressures are recorded when the sounds are first heard and when they disappear, respectively.

Interpretation of Blood Pressure Readings

  • Normal: Systolic <120 mmHg and Diastolic <80 mmHg.
  • Elevated: Systolic 120-129 mmHg and Diastolic <80 mmHg.
  • Hypertension Stage 1: Systolic 130-139 mmHg or Diastolic 80-89 mmHg.
  • Hypertension Stage 2: Systolic ≥140 mmHg or Diastolic ≥90 mmHg.
  • Hypertensive Crisis: Systolic >180 mmHg and/or Diastolic >120 mmHg.
