摘要
目的 探讨Ⅱ型呼吸衰竭患者动、静脉血PCO2 之间的相关性。方法 对 3 1例Ⅱ型呼吸衰竭患者同时做动、静脉血PCO2 测定。结果 3 1例Ⅱ型呼吸衰竭患者静、动脉血PCO2 差值为 0 .92± 0 .12kPa( 6.92± 0 .92mmHg)。经t检验 ,t=1.89,P <0 .0 5。结论 Ⅱ型呼吸衰竭患者静脉血PCO2 与动脉血PCO2 之间存在一定相关性 ,取其静脉血PCO2 可反映动脉血PCO2 ,采静脉血测定PCO2 可减轻患者痛苦及创伤。
Objective To study the correlation of PCO 2 between venous (PCO 2) and arterial blood (PaCO 2). Methods PCO 2 of venous and arterial blood of 31 patients with type-II respiratory failure (hypoxemic plus hypercapnic respiratory failure) were examined at the same time. Results The difference of PCO 2 at venous and arterial blood reached 0.920.12 kPa, with PvCO 2-PaCO 2=6.920.92 mmHg. Treated with t test, the results showed t=1.89, with P <0.05. Conclusion In type-II respiratory failure patients, PCO 2 is closely related to venous and arterial blood. Examination of PvCO 2 instead of PaCO 2 not only relieves patients' pains and decrease economical burden, but also improves the nursing efficiency.
