The most important preoperative cardiopulmonary variables for identifying patients at increased risk prior to lung resection are: FEV1, FEV1-ppo, DLCO, MVO2, and SO2. The aim of this study was to evaluate the ability and usefulness of predictive postoperative FEV1 (FEV1-ppo) in 80 patients undergoing lung resection. Spirometry was performed before and 6 months after operation; residual respiratory function was calculated using Nakahara's formula, and data analysis calculations were performed using the chi 2 test. It was observed that the resulting predictive values were almost comparable to the values observed 6 months postoperatively in 63.75% of patients and the correlation proved statistically significant (P < 0.005). In view of its simple and rapid execution, we conclude that Nakahara's formula, compared with the others, remains a reliable standard method of assessing high-risk patients and planning appropriate surgery.
第一秒用力呼气容积（FEV1）、预计第一秒用力呼气容积（FEV1-ppo）、一氧化碳弥散量（DLCO）、最大摄氧量（MVO2）和血氧饱和度（SO2）。本研究的目的是评估80例接受肺切除手术患者术后预测第一秒用力呼气容积（FEV1-ppo）的能力和实用性。在手术前和术后6个月进行肺功能测定；使用中原公式计算残余呼吸功能，并使用卡方检验进行数据分析计算。观察到在63.75%的患者中，所得预测值与术后6个月观察到的值几乎相当，且相关性具有统计学意义（P < 0.005）。鉴于其操作简单快捷，我们得出结论，与其他方法相比，中原公式仍是评估高危患者和规划适当手术的可靠标准方法。
