Previous research shows that maximum interface pressure increases when the patient is lying in the lateral position. However, it was unclear whether it was better to increase or decrease the internal air pressure to reduce the maximum interface pressure in the lateral position; thus, this study investigated this issue. In this study, we investigated the change in pressure redistribution because of the difference in internal air pressure between the supine and lateral positions on an active air mattress for pressure ulcer prevention management. Each participant's five internal air pressure values served as the independent variables. The interface pressure on the active air mattress was measured for 20 minutes. The sacral left iliac crest and left greater trochanteric interface pressures were measured using a portable pressure-measuring device. When seven of the 10 participants switched from the supine position to the left lateral position, there was a decrease in the maximum interface pressure as the internal air pressure increased. The maximum interface pressure in the greater trochanter in the lateral position was twice that in the sacral region in the supine position. These results show that increasing the internal air pressure in the lateral position might help reduce the maximum interface pressure.
先前的研究表明，当患者处于侧卧位时，最大界面压力会增加。然而，尚不清楚增加还是减少内部气压以降低侧卧位的最大界面压力更好；因此，本研究对此进行了调查。在这项研究中，我们研究了由于仰卧位和侧卧位之间的内部气压差异，对用于预防压力性溃疡管理的主动气床垫压力再分布的影响。每个参与者的五个内部气压值作为自变量。使用便携式压力测量设备测量主动气床垫上的界面压力 20 分钟。使用便携式压力测量设备测量骶骨左侧髂嵴和左侧大转子的界面压力。当 10 名参与者中的 7 名从仰卧位切换到左侧卧位时，随着内部气压的增加，最大界面压力降低。侧卧位时大转子处的最大界面压力是仰卧位时骶骨区域的两倍。这些结果表明，增加侧卧位的内部气压可能有助于降低最大界面压力。
