Numerous problems can occur with liquid oxygen delivery systems, in part because of the complexities of such systems. These systems must comply with guidelines of the Joint Commission on Accreditation of Hospitals. During the past year, 18 major problems with the liquid oxygen delivery system have occurred at the authors' hospital. Five times, false alarms have resulted from calibration drift in line pressure sensors. Thrice, excessive depletion of the reverse supply has occurred because of pressure imbalance between the main and reserve systems. Twice, excessive depletion of the reserve supply occurred owing to failure of the vacuum seal on the reserve supply vessel. Eight other potentially serious mishaps have also been reported. These problems, which are inherent in liquid oxygen delivery systems, are for the most part preventable.
液氧输送系统可能会出现许多问题，部分原因在于此类系统的复杂性。这些系统必须符合医院评审联合委员会的指导方针。在过去一年里，作者所在医院的液氧输送系统出现了18个主要问题。线压力传感器的校准漂移导致了5次误报。主系统和备用系统之间的压力不平衡导致备用供应过度耗尽3次。备用供应容器上的真空密封失效导致备用供应过度耗尽2次。还报告了其他8起潜在的严重事故。这些液氧输送系统中固有的问题大多是可以预防的。
