4、s requirements for portable lung ventilators designed for use in emergency situations and transport. Emergency and transport ventilators, called hereafter “ventilator”, are often installed in ambulances or other types of rescue vehicles, but are often used outside this environment, where they have t

5、o be carried by the operator or other persons. These devices will frequently be used outside the hospital or home by personnel with different levels of training. This part of IS0 10651 is also applicable to devices permanently mounted in ambulances or aircraft. This part of IS0 10651 does not cover
