The effect of increasing pneumatic splint pressure on cutaneous oxygen tension measured transcutaneously (TcPO2) was investigated in 12 subjects. The mean initial TcPO2 was 70.6 mmHg. TcPO2 decreased linearly on increasing the pressure within the splint. TcPO2 became zero at a mean splint pressure of 28 mmHg. Second, three accepted methods used by the ambulance crew to assess inflation pressures of the splint were investigated and found to be unreliable. In the light of these findings the risk of ischaemic complications as a result of applying pneumatic splints to a fractured limb is discussed. We advocate a recommended maximum splint pressure of 15 mmHg and that the splint should be manufactured with a security blow-off valve set at 15 mmHg.
对12名受试者研究了增加气动夹板压力对经皮测量的皮肤氧张力（TcPO2）的影响。初始平均TcPO2为70.6 mmHg。随着夹板内压力增加，TcPO2呈线性下降。在平均夹板压力为28 mmHg时，TcPO2变为零。其次，对救护人员用于评估夹板充气压力的三种公认方法进行了研究，发现这些方法不可靠。根据这些发现，讨论了对骨折肢体应用气动夹板导致缺血性并发症的风险。我们建议夹板的推荐最大压力为15 mmHg，并且夹板应配备设定为15 mmHg的安全放气阀。
