摘要
目的 :了解采用改进后的双流向面罩行机械通气时二氧化碳的排出情况。方法 :选取符合条件的慢性阻塞性肺病 (COPD)并Ⅱ型呼吸衰竭病人 3 0例 ,随机分为试验组和对照组 ,试验组采用改进后的双流向面罩通气 ,对照组采用传统面罩通气 ,观察两组血气分析情况。结果 :试验组PaCO2 明显降低 (P <0 .0 1) ,两组使用前后PaCO2 经差值的t检验 ,有统计学意义 (P <0 .0 1)。结论 :使用双流向面罩通气 ,能明显降低COPD并Ⅱ型呼吸衰竭病人二氧化碳潴留。
Objective: to find out carbon dioxide output in patients with chronic obstructive pulmonary diseases (COPD) after applying modified double-direction airflow mask. Methods: a total of 30 cases who had diagnosed as COPD complicated with type Ⅱ respiratory function failure were selected and divided into test and control group randomly. Patients of test group were used the modified ventilation mask. While patients of control group were given oxygen inhalation in traditional mask. Blood-gas analysis of patients in the two groups was observed. Results: PaCO 2 in patients of test group lowered remarkably than that in patients of control group (P<0.01). There is statistical significance between the two groups in terms of the PaCO 2 remainder of before and after the use of ventilation mask (t test,P<0.01). Conclusion: to use double-direction airflow mask in COPD complicated with type Ⅱ respiratory function failure patients could obviously improve their carbon dioxide retention.
