CGA P-2.7仅适用于以下类别的液氧系统:为个别患者提供补充氧气治疗的小型基础储氧单元系统；医疗机构工作人员在设施内转移患者时使用的系统；以及医疗机构内单个患者的医疗系统。本出版物不适用于可连接到医疗设施偏远区域的分配管道上的大型便携式液氧系统。参见NFPA 99《医疗设施标准》和CGA SB-26《便携式液体低温钢瓶上的钢瓶连接》，了解有关此类容器储存、搬运和使用的更多信息。 本出版物的目的是描述在医疗设施内使用液氧系统时应遵循的建议预防措施和安全程序。氧气处理不当对受过训练和未受过训练的人都有潜在危险。因此，负责氧气设备及其使用的人员必须熟悉氧气的危害、设备的操作特性以及使用时应遵守的预防措施。

CGA P-2.7 applies only to liquid oxygen systems in the following categories:small base reservoir unit systems providing supplemental oxygen therapy for individual patients;systems used by health care facility staff when moving patients within the facility; andambulatory systems for an individual patient within a health care facility.This publication does not apply to larger portable liquid oxygen systems that can be attached to distribution piping in a remote area of the healthcare facility. See NFPA 99, Standard for Health Care Facilities, and CGA SB-26, Cylinder Connections on Portable Liquid Cryogenic Cylinders, for further information regarding the storage, handling, and use of these types of containers.The purpose of this publication is to describe the recommended precautions and safety procedures to be followed when liquid oxygen systems are used within health care facilities. Mishandling of oxygen presents potential hazards to both trained and untrained persons. It is therefore important that personnel who assume the responsibility for oxygen equipment and its use be familiar with the hazards of oxygen, the operational characteristics of the equipment, and the precautions to be observed while using it.
