Smartphone app for measuring capillary refill time
This trial tests if a smartphone app can accurately measure capillary refill time (how quickly blood returns to your skin after pressing it) in ICU patients. This might help doctors monitor blood flow more easily.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older.
- You are currently in an intensive care unit (ICU).
- Your doctor needs to check your capillary refill time (a quick bedside test of blood flow).
- You or your legal representative must agree to participate.
- You cannot have skin problems, severe blood vessel disease, or a missing finger at the measurement site.
- Your fingers must not have tattoos, large scars, or moles that could interfere with the app or your privacy.

This trial tests a new way of giving fluids and medicines to people with septic shock. It focuses on a simple sign called capillary refill time (how fast color returns when you press a fingernail) to guide treatment, aiming to improve recovery.
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.
This study looks at two ways to check blood flow and oxygen use in people with septic shock, a severe infection-related condition. It aims to see if a simple bedside test (fingertip refill) and a blood measure (oxygen extraction ratio) agree, which could help guide treatment.
This trial tests whether a smartphone app can accurately measure your blood pressure without a cuff. It may help find people with high blood pressure early using only a phone.
This study tests an app that uses your phone's camera to measure blood pressure at home. You will use the app and a blood pressure cuff to see if the app works well.
This study tests whether a mobile health app can help ICU staff notice serious changes in patients' conditions earlier. If you have a loved one in the ICU, this app could lead to quicker responses and better care during their stay.
