Can a simple bedside measurement help doctors spot heart problems in critically ill patients?

This study is testing whether doctors can use a simple measurement called pulse pressure — the difference between your highest and lowest blood pressure — to detect when the heart isn't pumping enough blood to the body's organs in critically ill patients. Researchers want to understand if this easy, inexpensive bedside check can help doctors spot serious circulation problems early and decide when to start treatment, without needing expensive monitoring equipment.

In intensive care units, doctors often need to quickly spot when a patient's heart isn't pumping enough blood to keep organs healthy, but there's no simple, affordable tool available to all patients. This study aims to see if a basic blood pressure measurement could serve as an early warning sign so doctors can act faster to help patients, especially in emergency departments or hospitals with limited resources.
