背景资料：爬楼梯试验常用于肺切除术前评估，但其标准化困难且提供的生理信息很少。目的：验证爬楼梯试验中测得的VO（2peak）与海拔高度的相关性。研究方法：对109例肺切除术后患者进行了限制性爬楼梯试验，并使用便携式气体分析仪直接测量VO（2peak）。采用逐步logistic回归和bootstrap分析来验证几个围手术期变量与VO（2peak）的相关性
Background: The stair-climbing test is commonly used in the preoperative evaluation of lung resection candidates, but it is difficult to standardize and provides little physiologic information on the performance. Objective: To verify the association between the altitude and the VO(2peak) measured during the stair-climbing test. Methods: 109 consecutive candidates for lung resection performed a symptom-limited stair-climbing test with direct breath-by-breath measurement of VO(2peak) by a portable gas analyzer. Stepwise logistic regression and bootstrap analyses were used to verify the association of several perioperative variables with a VO(2peak)
