| Outline of Final Research Achievements |
In this study, we tried to quantify the capillary refill time (Q-CRT) measured from a change of light intensity in near infrared and red light before and after the compression of finger nail bed based on a principle of pulse oximeter. Mean value of Q-CRT of healthy adult volunteers was 1.6 seconds. Since there was the difference of measured value of Q-CRT between the examiners, we developed the new device for measurement of Q-CRT by the automatic and constant pneumatic compression to finger nail bed. In addition, we focused on the difference of light intensity during compression of finger nail bed between infra-red and red light (ΔAb). TheΔAb more than 0.06 was well correlated to the status with blood lactate level more than 2.0 mmol/l.
