Question

The instrument used for measuring blood pressure is-
A. ECG
B. Stethoscope
C. Sphygmomanometer
D. EEG

Answer 1

Hint: An instrument made up of an inflatable cuff to collapse and then release the artery in a controlled manner under the cuff, and a pressure measuring manometer of mercury or aneroid.

Complete answer:
Option A is incorrect. In order to search for multiple heart problems, an electrocardiogram (ECG or EKG) records an electrical signal from your heart. To record your heart's electrical signals, which cause your heart to beat, electrodes are placed on your chest. On an attached computer display or printer, the signals are displayed as waves.
Option B is incorrect. Stethoscope is a sound magnifying listening aid that is used which consists of two earpieces linked by tubes that deliver the sound to the earpieces from the end piece, which is situated above the artery. Dental specialists should invest in quality stethoscopes that easily detect sound. To hear sounds, providers do not have to strain. Replace components with existing stethoscopes or, if necessary, replace the entire stethoscope.
Option C is correct. There is an inflatable cuff and two tubes in the sphygmomanometer (blood pressure cuff or machine); the pressure control bulb is connected to one tube and the pressure gauge to the other tube. The patient's size determines the size of the chosen cuff. The blood pressure reading is too high when a cuff is too narrow; the reading is too low when the cuff is too wide.
Option D is incorrect. The procedure used to measure electrical activity in the brain is an electroencephalogram (EEG) via electrical impulses, brain cells interact with each other. To help identify possible issues associated with this operation, an EEG can be used. An EEG tracks brain wave patterns and documents them.

So, the correct answer is Option C.

Note: The operator in sphygmomanometer records the blood pressure levels in mm Hg by examining the mercury in the panel, or the aneroid gauge pointer, when releasing the air pressure with a control valve. During the cardiac cycle, the highest pressure in the arteries is systolic pressure, and diastolic pressure is the lowest pressure (at the resting stage of the cardiac cycle).
