Continuous assessment of the cardiovascular system of the critically ailing patients is important to diagnose and manage their complex medical conditions. Hemodynamic forces circulate blood through the body. Hemodynamic monitoring system is used to monitor blood pressure, oxygenation of tissues and organs, and cardiac output within the cardiovascular system. It provides quantitative information about vascular capacity, pump effectiveness, blood volume, and tissue perfusion. It also helps in early detection, treatment, and identification of conditions such as heart failure and cardiac tamponade. It is used to evaluate the patient's immediate response to treatment and the effectiveness of cardiovascular functions such as cardiac output and index. Some of the indications for carrying out hemodynamic monitoring are decreased cardiac output, shock, decreased urine output, dehydration, burns, gastrointestinal bleeding, and loss or deficit of cardiac functions such as myocardial infarction, congestive heart failure, and cardiomyopathy. It is assessed either through non-invasive single parameter indicators or various invasive techniques that provide multi-parameter hemodynamic measurements. Invasive hemodynamic measurement techniques facilitate the monitoring of intra-arterial blood pressure, left atrial pressure, central venous pressure, and pulmonary artery pressure. Hemodynamic monitoring equipment consists of a transducer, monitor, fluid filled catheter, and tubing and flush system. Invasive pressure monitoring requires insertion of a catheter into an artery or vein or a heart chamber. Non invasive and intra arterial blood pressure measurement, central venous pressure, and pulmonary artery catheter pressure monitoring are some of the methods for hemodynamic monitoring. It can lead to complications such as pain, infection, external hemorrhage, pulmonary infarction, air embolism, pulmonary artery rupture, blood loss, and massive ecchymosis. Hemodynamic monitoring systems are used in hospitals, cath labs, and home and ambulatory sites.
