About

Comparison of a peripheral perfusion assessment method using a pulse oximeter to the conventional capillary refill time visually assessed by a clinician.

Full description

A new technology, capillary refill index (CRI), to assess peripheral perfusion status quantitatively using pulse oximeter waveforms is being developed. The conventional capillary refill time (CRT) is widely used in clinical settings as a gold standard to assess peripheral perfusion.

The objective of this study is to evaluate the capability of CRI to predict altered peripheral perfusion determined with the conventional CRT test. Predictive capability of CRI needs to be assessed to achieve a goal to provide clinicians with an alternative method to the conventional CRT.
