Hemodynamic Monitoring aims to incorporate data on patient characteristics into a course of action that enhances the patient's outcome. Monitoring the electrocardiogram (ECG) allows for continuous monitoring of heart rate, diagnosis of myocardial ischemia, and identification of arrhythmias and conduction anomalies. Paying close attention to lead location and selection, filter selection, and gain that will affect the presented ECG tracing is necessary for accurate and dependable ECG monitoring. For the most accurate identification of myocardial ischemia, a precordial anterolateral lead (V3, V4, or V5) should be chosen. Hemodynamic Monitoring System is the continuous evaluation of circulatory performance. Physiologic stress, such as surgery, is likely to cause changes in the circulatory system. These disturbances, if left unchecked, might cause tissue hypoxia and, as a result, perioperative morbidity and mortality. As a result, providing safe anesthetic care requires hemodynamic monitoring as a vital part. It is important to remember, nevertheless, that hemodynamic monitoring does not alter the course of anaesthesia or surgery on its own. Hemodynamic Monitoring Systems must be of good quality and the measurements must be accurately interpreted in order for the anesthesiologist to intervene in a suitable and timely manner in order to improve perioperative outcomes. Inaccurate treatment decisions brought on by poor measurement quality or an inaccurate interpretation of hemodynamic monitors will have unfavourable effects. Hemodynamic Monitoring Systems goals include providing a continuous evaluation of systemic and intracardiac pressures as well as a way to measure CO and, in turn, compute systemic and pulmonary resistances. To monitor systemic pressure, an arterial catheter is often inserted in the radial artery. Typically, the resulting diastolic pressure correlates well with non-invasive measurements. Due to a very transient pressure peak in the early stages of systole, systolic pressure may be much greater than non-invasive measurements. The pressure increase barely affects MAP. In most cases, the non-invasive assessment is more clinically applicable to the patient's condition. The patient is relieved from the agony of repeated blood draws thanks to the arterial catheter, which makes it simple to sample arterial blood. Through the insertion of a catheter into the central venous system and advancement into and through the right side of the heart, measurements of intracardiac pressures and CO are obtained. The right internal jugular vein is most frequently used to gain venous access, while a subclavian route is also an option. Traditionally, the landmarks of the clavicle and the sternocleidomastoid muscle are used to guide insertion. A vaginal probe's higher-frequency ultrasound transducer can also be utilized to make insertion under direct vision easier. A pulmonary artery catheter can be "floated" into the right side of the heart and pulmonary artery once central venous access has been established and verified. Pneumothorax (0.1%), pulmonary infarction (0%–1.3%), pulmonary artery rupture (0.1%), and septicemia (0.5%–2.0%) are the most common complications from pulmonary artery catheterization in skilled hands. Arrhythmias are typically brief and connected to the catheter's passage through the RV. Maintaining placement in the pulmonary artery may be challenging if the patient has significant pulmonary hypertension.
