Decreasing arterial oxygen saturation has been reported in patients with cystic fibrosis during postural drainage when this was combined with other manoeuvres, which did not, however, include thoracic expansion exercises or pauses for relaxation and breathing control. When these features were included in an active cycle of breathing techniques during postural drainage in 20 patients with cystic fibrosis there was no fall in arterial oxygen saturation during the procedure (mean values 87.1%, 87.9%, and 86.7% before, during, and after treatment).
据报道，囊性纤维化患者在体位引流并结合其他操作时动脉血氧饱和度会降低，但这些操作未包括胸廓扩张运动或放松及呼吸控制的暂停。当在20例囊性纤维化患者的体位引流期间，将这些特征纳入主动呼吸循环技术时，在操作过程中动脉血氧饱和度没有下降（治疗前、治疗期间和治疗后的平均值分别为87.1%、87.9%和86.7%）。
