Testing blood-flow monitoring during controlled fluid loss

This study tests whether a simple bedside test—raising your legs while lying down—can help doctors decide if you need more fluids. It uses an ultrasound to measure how well your heart pumps blood during this test.

This trial studies how blood flow and organ “perfusion” look in ICU patients who are struggling with infection and low blood pressure. It may help doctors better measure and manage shock by comparing hemodynamic readings during standard treatment.

This study uses a device that applies gentle suction to your lower body to see how well a monitor tracks your body's response. It may help improve monitoring for people with conditions like fainting or dizziness.

This study compares three different methods used by doctors to check if giving fluids through an IV helps improve blood pressure in people with sudden circulatory failure. It helps doctors find the quickest and most accurate way to guide treatment.

This study tests special ways of analyzing blood-pressure recordings during major surgery to better understand why some people develop low blood pressure (hypotension). If you have high blood pressure and need invasive blood-pressure monitoring, your surgery team will use readings to study patterns that may help predict or prevent low blood pressure.

This study tests how doctors can monitor your blood flow and fluid needs while you are on VV-ECMO. It involves a simple maneuver where your legs are raised to see if your heart needs more fluid.
