Measuring blood pressure is an operation that nurses often need to do and must be mastered as a nurse. When measuring blood pressure using a mercury sphygmomanometer, the position where a blood pressure cuff is wrapped and the tightness of wrapping of the blood pressure cuff are very important for accurately measuring blood pressure. Therefore, the health care personnel must correctly master the winding position and tightness of the blood pressure cuff so as to standardize the winding of the blood pressure cuff of the sphygmomanometer during the exercise.

The upper brachial artery and the popliteal artery of the lower limb are common sites for measuring blood pressure. When measuring the upper limb brachial artery blood pressure, the lower edge of a blood pressure cuff of the sphygmomanometer is required to be 2-3 cm away from an elbow fossa, and the convoy does not have good grasp on the standard distance during the practice, so that the blood pressure cuff cannot be wound at the standard position. When measuring the blood pressure of the popliteal artery of the lower limb, the lower edge of a blood pressure cuff of a sphygmomanometer is required to be 3-5 cm away from the popliteal fossa. Whether measuring the brachial artery of the upper limb or the popliteal artery of the lower limb, one or two fingers should be inserted for the measurement of tightness. The convalescent person can not better control the winding position of the blood pressure cuff on the standard position because the convalescent person can master the distance which is not well standardized during the exercise; furthermore, the tightness of the wrapping of the blood pressure cuff cannot be controlled better, and the blood pressure cuff is often wrapped too loosely or too tightly, so that the blood pressure measurement results are not accurate enough.
