A residual postive pressure (R.P.P.) of low magnitude (1 to 4 cm of water) was used during assisted ventilation by pressure relaxator in an attempt to decrease the expiratory dynamic compression of the airways. A ventilatory test involving 80 respiratory insufficient patients (73 men and 7 women) shows that with assistance the tidal volume of half of the subjects increased by more than 20% (average gain: 32%). The patients with the highest RV/TC ratio benefitted most from the method. Finally, the arterial blood gases were not significantly modified. A longitudinal study involving 46 subjects observed for an average period of 24 months revealed a marked subjective improvement in the patients' condition without significant modification of the blood gas figures. No incident or accident was attributed to the use of R.P.P.
在使用压力缓解器进行辅助通气时，采用了低幅度（1至4厘米水柱）的残余正压（R.P.P.），试图减少气道的呼气动态压缩。一项涉及80名呼吸功能不全患者（73名男性和7名女性）的通气测试表明，在辅助通气时，一半受试者的潮气量增加超过20%（平均增加：32%）。右心室/总肺活量（RV/TC）比值最高的患者从该方法中获益最大。最后，动脉血气没有明显改变。一项对46名受试者进行的纵向研究，平均观察期为24个月，结果显示患者的状况有明显的主观改善，而血气数值没有显著变化。未发现因使用R.P.P.而导致的任何事件或事故。
