Testing a new way to measure blood flow under the tongue
This study tests how repeatable a new way to measure tiny blood vessels under the tongue is. It looks at both healthy people and very ill patients in the intensive care unit to see if the measurement is consistent.
Summary written for real people, not researchers, by Clin2.
Who can take part
- For healthy volunteers: be between 18 and 40 years old and in generally good health
- For healthy volunteers: no chronic diseases and no long-term medications
- For healthy volunteers: avoid caffeine, nicotine, and alcohol for 12 hours before the test
- For ICU patients: be over 18 years old and currently in the intensive care unit
- For ICU patients: need medications to support blood pressure and be on a breathing tube

This study checks if a simple blood flow measurement can help predict which patients with sepsis are at higher risk of dying within 28 days. The goal is to see if this test can guide treatment decisions in the ICU.
This study monitors tiny blood vessels under the tongue using a non-invasive device to see how well blood flows in ICU patients on a breathing machine. Researchers hope to improve care for patients with serious infections or shock.
This trial tests whether a simple ultrasound measurement of blood flow in your heart, guided by artificial intelligence, can be reliably done by minimally trained staff. It aims to help doctors decide when to give fluids to ICU patients who need them.
This study looks at how blood flow in the brain changes when blood pressure rises or falls in people in the ICU. It may help doctors understand safer ways to manage blood pressure in critically ill patients.
This study tests how well certain monitors measure oxygen and blood thickness in healthy volunteers. It helps improve devices used in hospitals to keep patients safe.
This study tests a new way to check blood flow in the tiny blood vessels of the skin for people in the ICU with circulatory failure from sepsis or heart failure. It helps doctors understand how well blood is reaching tissues, which may guide treatment.
