About this study

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.

Treatment and study plan

capillary refill index (CRI)

Device

a waveform analysis method using a pulse oximeter to assess peripheral perfusion

Primary outcomes

  1. Predictive Capability of the Altered Peripheral Perfusion

    Time frame: < 30 min *right after enrollment

    The area under the curve (AUC) of the receiver operator characteristic (ROC) curve analysis on CRI values to predict probability of altered peripheral perfusion determined with the CRT test.

Secondary outcomes

  1. Correlation of Device CRI to Conventional (Visual) CRT

    Time frame: < 30 min *right after enrollment

    Spearman's correlation coefficient to assess the correlation between CRI and CRT values.
