Clinical Warming Effectiveness of Conductive Fabric Warming vs Forced-air Warming Hypothermia with Forced-air Warming Conducve fabric warming (HotDog) showed significantly high- er warming rates than forced-air warming (FAW) (0.35˚C/hr vs 0.02˚C/hr), when all other relevant variables were held constant in a prospecve, randomized controlled trial. The temperature difference between the two groups was stascally significant at each data point aſter 30 minutes. The authors’ conclusion: “We conclude from these data that the clinical heat transfer effecveness of [HotDog warming] is signifi- cantly greater than FAW convecon. This is due to the combina- on of conducve heat transfer and the larger surface area of simultaneously heang from above and below the paent.” Hayashi, H; Koizumi, T; Sumita, S.; Yamakage, M.
