Nowadays, the most commonly used operating instrument in the medical industry is the ECG monitor. For blood pressure monitoring, the ECG monitor is the most commonly used. For these details, our editor from Jieruitai will introduce you to the ECG monitor blood pressure cuff. What does the logo mean?
The mark circled by the red five-pointed star indicates the midpoint of the airbag. When tying the cuff, the brachial artery of the limb should be placed here (on the upward extension line of the innominate point). The midpoint of the neonatal airbag coincides with the airway, so there is no additional mark. . The air bag of the cuff must cover more than 80% of the arm circumference, otherwise the measurement result will not be accurate.
The blue circle marks the maximum and minimum positions when the cuff is tied (the child's cuff range is marked on the reverse side). When the cuff is tied around the arm, if the white border printed with INDEX LINE does not reach the minimum mark, it indicates the sleeve used The strap is too large. If it exceeds the maximum mark, the cuff is too small.
Why is the cuff tightness of the electronic sphygmomanometer cuff to accommodate 1 finger, while the tightness of the cuff of the mercury sphygmomanometer is 1 to 2 fingers?
1. The material used for the cuff airbag of the mercury sphygmomanometer is different from that of the airbag in the non-invasive blood pressure monitor of the monitor. The former is made of rubber and the latter is PVC. The former is more flexible and compressive than the latter.
2. The measurement process of the mercury sphygmomanometer is the stethoscope listening to the Korotkoff sound when the blood flow is incompletely blocked by the cuff pressure. The non-invasive blood pressure measurement process of the monitor is the process of blood flow being completely blocked by the cuff pressure to no resistance. , The sensor captures the change in the gas amplitude in the airbag.
