Capillary refill time has been accepted as a method to manually assess a patient’s peripheral blood perfusion. Recently, temperature has been reported to affect capillary refill time and therefore temperature may interfere with accurate bedside peripheral blood perfusion evaluation. We applied a new method of analysis that uses standard hospital pulse oximetry equip- ment and measured blood refill time in order to test whether lowered fingertip temperature alters peripheral blood perfusion. Thirty adult healthy volunteers of differing races (skin colors) and age (young: 18–49 years and old: ≥ 50 years) groups were recruited. We created a high fidelity mechanical device to compress and release the fingertip and measure changes in blood volume using infrared light (940 nm). Capillary refill times were measured at the fingertip at three different temperature set- tings: ROOM TEMPERATURE, COLD by 15 °C cold water, and REWARM by 38 °C warm water. The COLD group has decreased fingertip temperature (23.6 ± 3.6 °C) and increased blood refill time (4.67 s [95% CI 3.57–5.76], p < 0.001). This was significantly longer than ROOM TEMPERATURE (1.96 [1.60–2.33]) and REWARM (1.96 [1.73–2.19]). Blood refill time in older subjects tended to be longer than in younger subjects (2.28 [1.61–2.94] vs. 1.65 [1.36–1.95], p = 0.077). There
