Halothane changes the relationships between lung resistances and lung volume.

abstract：BACKGROUND:Previous attempts at improving operating room utilization have generally emphasized more accurate scheduling, starting the first case on time, and reducing turnover time. Surgical case cancellations have largely been ignored except for recommendations for preoperative screening and good physician-patient com...
