Background

The central venous pressure is the pressure of the superior and inferior vena cava entering the right atrium, is measured by the superior and inferior vena cava or the right atrial internal catheter, is the right atrial pressure reflected, and is one of the main indexes for clinical observation of hemodynamics. The magnitude of the central venous pressure depends on the correlation between the ability of the heart to eject blood and the amount of venous return. If the heart has strong blood ejection capability, the blood returning to the heart can be ejected into the artery in time, and the central venous pressure is low. Conversely, a decrease in ejection capability due to heart failure or the like will result in an increase in central venous pressure. The method for measuring the central venous pressure commonly used at present has two methods, one is to use a transducer, so that the operation is simple and convenient, the measurement is accurate, and the cost is higher; secondly, the infusion tube is at the same atmospheric pressure, the crossing point of the axillary midline and the fourth rib is taken as the zero point, and the height of the liquid level in the infusion tube is measured, the method has lower cost and simple and convenient operation, but the method needs to hold a ruler and other instruments with measuring scales to measure the height of the liquid level in the infusion tube, the operation is inconvenient when the ruler is held by hand, and the inaccuracy of the measuring result is easy to cause.
