通过分别对腹膜透析、血液透析病人肺功能的连续监测，发现已受损的通气功能和弥散功能明显改善，且通气功能的恢复快于弥散功能，出现肺功能损害的逆转过程。发现残气量、一氧化碳弥散量在腹透液存在时或不存在时显示明显差异（Ｐ＜０．０５），说明腹透液的存在对肺功能指标有影响，但对肺机能影响不明显。 Through continuous monitoring of lung function of peritoneal dialysis patients and hemodialysis patients respectively, it was found that the impaired ventilation function and diffusing function were significantly improved, and the recovery of ventilatory function was faster than that of diffuse function, and the reversal of lung dysfunction appeared. Found that the amount of residual gas, carbon monoxide dispersion in the presence or absence of peritoneal dialysis fluid showed significant differences (P <0.05), indicating the presence of peritoneal fluid on the index of pulmonary function, but no significant effect on the lung function.
