What are the parts of the body where blood pressure is measured?

1. Brachial artery of the upper arm: the position is sitting or supine, with the lower edge of the cuff 2-3 cm from the elbow fossa and loosened so that it can be inserted one finger. The chest piece of the stethoscope is placed at the most obvious fluctuation of the brachial artery.

2. Dorsalis pedis artery: the position is supine, the lower edge of the cuff is 3-4 cm from the ankle of the lower leg, and the elasticity is such that one finger can be inserted. The stethoscope chest piece is placed on the dorsalis pedis artery.

3. Popliteal artery: Position is supine, prone, or lateral, usually not in the bent knee supine position. The lower edge of the cuff is 3-4 cm from the popliteal fossa. the chest piece of the stethoscope is placed at the most obvious fluctuation of the popliteal artery.

1,The manual auscultation method sphygmomanometer is the use of mercury, etc., as a manometer, and the measurer uses the human ear to listen to the original blood pressure Koch sound (from heavy to light and then disappearing or changing) through a stethoscope and reads the systolic and diastolic pressure according to the Koch sound heard in conjunction with the manometer; although the auscultation method method is currently an accurate method of measuring blood pressure, the manual auscultation method is influenced by several factors, including.

(1) The level of training received;

(2) Hearing;

(3) Attention;

(4) Poor visualization in judgment. The reliability of blood pressure measurement is entirely determined by the level of expertise, hearing, fatigue and work attitude of the measurer, and because blood pressure is an instantaneous value, not repeatable and not compoundable, how much the measurer says is how much.
