Arterial Dynamic Elastance in ICU Patients on Inotropic or Vasopressor Drugs

This study focuses on assessing the cardiovascular health and blood flow dynamics in patients who are in Intensive Care Units (ICU) and depend on drugs that support heart function or blood pressure. These drugs, known as inotropes and vasopressors, help the heart pump more effectively or raise blood pressure. The aim is to understand how these patients' hearts and blood vessels respond to treatment by monitoring changes in blood flow and pressure. By doing so, the study hopes to improve patient care by optimizing how fluids and medications are administered, particularly in critical conditions where the heart and blood circulation are compromised. Participants in this study will undergo monitoring that combines blood pressure readings with tools that measure how much blood the heart pumps. This monitoring can be done using devices that might either be placed on the skin or require a small procedure to place them inside the body. The study evaluates a measurement called dynamic arterial elastance, which helps understand the relationship between changes in blood pressure and blood flow during each heartbeat. The results will be captured on a hemodynamic monitor, which provides real-time feedback to help adjust medical care. This approach aims to tailor treatment for better clinical outcomes in ICU settings.
