Which instrument is used to measure the blood pressure manually?

The correct answer is Sphygmomanometer.

Key Points

• A Sphygmomanometer is a medical instrument used to measure blood pressure manually.
• The device typically consists of an inflatable cuff, a measuring unit (manometer), and a mechanism for inflation (bulb or pump).
• Blood pressure is measured in millimeters of mercury (mmHg) and recorded as two numbers: systolic pressure (higher) over diastolic pressure (lower).
• Manual sphygmomanometers are commonly used with a stethoscope to listen to the arterial blood flow sounds during measurement.
• It is widely used by healthcare professionals for accurate and reliable blood pressure readings.

Additional Information

• Types of Sphygmomanometers
  • There are three main types: Mercury, Aneroid, and Digital sphygmomanometers.
  • Mercury sphygmomanometers are considered the gold standard for accuracy.
  • Aneroid devices use a mechanical gauge and require regular calibration.
  • Digital devices are user-friendly and suitable for home use but may have slight accuracy variations.
• Korotkoff Sounds
  • These are the sounds heard through a stethoscope while measuring blood pressure using a manual sphygmomanometer.
  • They indicate changes in blood flow and are used to determine systolic and diastolic pressures.
• Hypertension and Hypotension
  • Hypertension: High blood pressure, typically defined as 140/90 mmHg or higher.
  • Hypotension: Low blood pressure, typically below 90/60 mmHg.
  • Both conditions require accurate measurement for diagnosis and treatment.
• Importance of Blood Pressure Monitoring
  • Regular monitoring helps in early detection of cardiovascular diseases.
  • It aids in managing chronic conditions like hypertension and diabetes.
  • Monitoring is crucial during pregnancy to prevent complications such as preeclampsia.
