Abstract:
Central venous pressure (CVP) reflects the comprehensive condition of effective blood volume, cardiac function and vascular tone. Clinical monitoring of CVP can indirectly understand and evaluate the dynamic changes of blood volume in patients, and provide a reference for patients to venous fluid. At present, the traditional manual measurement method is widely used for measurement, which has some shortcomings such as zero shift, cumbersome operation (requires two health care workers to cooperate). In order to overcome the above problems, the author invented a new fixable CVP measurement tool and obtained the national utility model patent (ZL 2021 2 1451705.7). The tool is mainly composed of a base plate, a movable frame and a measuring department, etc. When used, the base plate is placed into the back of the patient and pressed and fixed, the movable frame is adjusted, the zero point is found, and the measurement data is read from the measuring department. It has the advantages of simple and convenient operation, small measurement error, wide applicability (different body types) and so on, which is suitable for clinical promotion.
