Traditional hemodynamic monitoring

Traditional hemodynamic monitoring methods are not widely used in many primary hospitals and cannot achieve long-term continuous monitoring. Pulmonary thermodilution is the gold standard for cardiac function monitoring, but it is difficult to achieve due to the aggressiveness of newborns. Ultrasound cardiac output monitor (uscom) and electronic heart force monitor (icon) are two non-invasive functional monitoring methods, which can effectively monitor changes in cardiac function and reflect changes in cardiac function and hemodynamics. Ultrasonic non-invasive output measurement system has the advantages of completeness, low cost, simple operation and continuous dynamic monitoring. It can monitor the blood flow signal of the aorta and pulmonary artery, compared to the pulmonary artery detection window (the original smes detection window of the aorta), because it has a richer blood flow signal, because it passes through the upper sternum, so it is to determine the aortic valve signal The most important way. Therefore, the aortic detection window is often used for clinical monitoring. This article mainly takes the research progress of these two methods as the starting point, and summarizes the progress of non-invasive functional monitoring in Linchuan application.
