 note = {We evaluated the correlation between routine preoperative spirometry and PaOｽﾞduring one-lung ventilation (OLV)in 75 patients who underwent open chest surgery in the lateral position.PaOｽﾞat 30 minutes after the start of OLV showed the lowest value and correlated inversely with preoperative ・V50/・V25 (r=0.47, p＜0.01).Also, preoperative ・V50/・V25 in 24 patients whose PaOｽﾞdecreased to less than 100 mmHg during OLV was 3.82±1.05 (mean±SD),which was significantly higher than that of the other patients (2.96±0.87,p＜0.01). ・V50/・V25 increases with obstructive disease of peripheral airways characterized by ventilation-perfusion inequality,and OLV may aggravate this inequality further.We therefore assume that PaOｽﾞduring OLV is apt to decrease in high preoperative ・V50/・V25 patients., Article, 信州医学雑誌 49(3): 147-150(2001)},
