Lower-limb intermittent sequential pneumatic compression (ISPC) improves circulation and vascular function in elderly adults. We evaluated the hypothesis that ISPC would also augment whole-body heat loss (WBHL) in elderly adults (aged 69 ± 4 years) resting in extreme heat (40 °C). While ISPC increased mean arterial pressure (91 ± 9 mm Hg) relative to no-ISPC (83 ± 5 mm Hg; = 0.013) at the end of the exposure, no influence on WBHL was observed (81 ± 7 and 86 ± 11 W for ISPC and no-ISPC, respectively, = 0.310). When assessed in elderly adults during an extreme heat exposure, intermittent sequential pneumatic compression augmented mean arterial pressure but did not enhance whole-body heat loss.
下肢间歇性序贯气动压迫（ISPC）可改善老年人的循环和血管功能。我们评估了以下假设，即在极端高温（40°C）下休息时，ISPC 也会增加老年人的全身热损失（WBHL）。虽然与无 ISPC 相比，ISPC 在暴露结束时使平均动脉压（91 ± 9 mm Hg）升高（83 ± 5 mm Hg；= 0.013），但对 WBHL 没有影响（ISPC 和无 ISPC 分别为 81 ± 7 和 86 ± 11 W，= 0.310）。在极端高温暴露期间评估老年人时，间歇性序贯气动压迫可增加平均动脉压，但不能增强全身热损失。
