We compared dynamic lung compliance (Cldyn) determined by the oesophageal balloon technique with static compliance of the respiratory system (Crs) determined by an airway occlusion technique in 10 newborn infants with various cardio-respiratory diseases. The correlation between the two variables was linear and statistically significant (r = 0.911, p less than 0.0003; Cldyn = 1.51.Crs-0.48). Crs varied significantly less than Cldyn (mean coefficient of variation 3.9 for Crs vs. 9.3 for Cldyn; t = 6.06, p less than 0.0002). Since Crs is closely related to lung compliance but a more reliable parameter and technically easier to assess, we recommend the assessment of Crs instead of Cldyn in clinical practice.
我们采用食管气囊技术测定动态肺顺应性（Cldyn），并采用气道阻断技术测定10例患有各种心肺疾病的新生儿的呼吸系统静态顺应性（Crs），对二者进行了比较。这两个变量之间的相关性呈线性且具有统计学意义（r = 0.911，p < 0.0003；Cldyn = 1.51.Crs - 0.48）。Crs的变化明显小于Cldyn（Crs的平均变异系数为3.9，而Cldyn为9.3；t = 6.06，p < 0.0002）。由于Crs与肺顺应性密切相关，但却是一个更可靠的参数，且在技术上更容易评估，因此我们建议在临床实践中评估Crs而非Cldyn。
