What is the special significance of the sign of the blood pressure cuff of the ECG monitor?

　　Nowadays, the commonly used operating instruments in the medical industry are ECG monitors. For blood pressure monitoring, ECG monitors are the most commonly used. For these details, our monitor manufacturer editor introduces you to the ECG monitor blood pressure cuffs. What does the sign mean?

　　The circle marked by the red five-pointed star indicates the midpoint of the balloon. When bracing the cuff, the brachial artery of the corresponding limb should be placed here (on the extension line of the unnamed point). The midpoint of the neonatal balloon coincides with the airway, so there is no other mark . The airbag of the cuff must cover more than 80% of the arm circumference, otherwise the measurement result cannot be accurate.

　　The blue circle marks the maximum and minimum positions when the cuff is bundled (the child's cuff range is marked on the reverse side). When the cuff is wrapped around the arm, if the white border printed with INDEX LINE does not reach the minimum mark, indicate the sleeve used If the belt is too large, the cuff is too small if it exceeds the maximum mark.

　　Why is the tightness of electronic blood pressure cuff cuff binding required to accommodate 1 finger, while the tightness of mercury cuff cuff binding is 1 to 2 fingers?

　　1. The cuff bladder of the mercury sphygmomanometer is different from the bladder in the cuff of the monitor noninvasive sphygmomanometer. The former is made of rubber and the latter is PVC. The former of the monitor manufacturer is more flexible and resistant to compression than the latter. .

　　2. The measurement process of the mercury sphygmomanometer is the stethoscope to listen to the Korotkoff sound when the blood flow is not completely blocked by the cuff pressure. The non-invasive blood pressure measurement process of the monitor is the blood flow is completely blocked by the cuff pressure to the process of no resistance In the sensor, the sensor captures the change in gas amplitude in the airbag.
