New gadget aims to take the guesswork out of a key emergency check
NCT ID NCT04538612
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a new device called DiCART that automatically measures capillary refill time — how quickly skin color returns after pressing it. Doctors use this to check blood flow in shock patients, but current manual methods vary a lot. The study involved 20 healthy adults who had temporary blood flow changes using a cuff, and the device's readings were compared to the standard finger-press method.

- Active substance
- DiCART TM device
- What this could lead to
- If successful, this device could provide a standardized, automated way to measure capillary refill time, helping doctors quickly assess blood flow in shock patients.
- What could go wrong
- This is a very small, early validation study in only 20 healthy people, not patients. The device may not work as well in real-world sick patients or different settings.
