Question

Объясните, как измеряют давление крови с помощью манометра

Answer 1

В манжету подается воздух, тем самым пережимая сосуды на руке. Манометр замеряет момент начала и конца пульса (то есть верхнее и нижнее давление), и показывает на шкале.

Answer 2

Measuring Blood Pressure with a Sphygmomanometer

To measure blood pressure using a sphygmomanometer, follow these steps:

1. Preparation: - Have the person sit in a comfortable position with their arm supported at heart level. - Wrap the blood pressure cuff around the upper arm, ensuring it's snug but not too tight.

2. Taking the Reading: - Inflate the cuff by squeezing the bulb until the pressure exceeds the expected systolic pressure. - Slowly release the pressure by turning the release valve, and listen for the first sound (systolic pressure). - Continue to slowly release the pressure and listen for the disappearance of the sound (diastolic pressure).

3. Reading the Results: - Note the pressure reading on the manometer when the first sound is heard (systolic pressure) and when the sound disappears (diastolic pressure).

4. Interpreting the Results: - The blood pressure reading is expressed as systolic pressure over diastolic pressure (e.g., 120/80 mmHg).

The sphygmomanometer measures blood pressure by detecting the sounds of blood flow as the pressure in the cuff is gradually released. This method provides important information about a person's cardiovascular health and is a key part of routine medical examinations.
