MICROCIRCULATION

This study looks at why some people who survive a serious illness in the ICU develop long-lasting muscle weakness. Researchers will test 50 former ICU patients with exercise on a bike to measure heart and muscle function. The goal is to better understand this condition, not to te…

This study looks at two methods to check blood flow in critically ill patients: the traditional capillary refill time (pressing on skin and timing color return) and the perfusion index (a continuous reading from a finger clip). Researchers want to see if the perfusion index can r…

This study looks at how giving fluids affects the smallest blood vessels in critically ill patients with venous congestion. Researchers will give a small amount of fluid and check blood flow in the mouth before, right after, and 30 minutes later. The goal is to see if fluids help…

This study tests whether measuring tiny blood flow (microcirculation) in sepsis patients in the emergency room can help doctors start fluid treatment earlier. Researchers will compare standard care plus these measurements to standard care alone in 556 adults with suspected sepsis…
