Lung ventilators for medical use — Part 2: Particular requirements for home care ventilators
Is part of a series of International Standards based on IEC 601-1:1988. Contains common requirements with IEC 601-2-12 and requirements from ISO 10651-1. It does apply the scope given in clause 1 of IEC 601-1 and specifies requirements for lung ventilators intended mainly for home care use.

Foreword
IS0 (the International Organization for Standardization) is a worldwide fed-
eration of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be rep-
resented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. IS0 col-
laborates closely with the International Electrotechnical Commission (IEC)
on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are cir-
culated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 10651-2 was prepared by Technical Committee
ISO/TC 121, Anaesthetic and respiratory equipment, Subcommittee
SC 3, Lung ventilators and related equipment.
IS0 10651 consists of the following parts, under the general title Lung
ventilators for medical use:
Part I: Particular requirements for critical care ventilators
- Part 2: Particular requirements for home care ventiia tors
Part 3: Particular requirements for emergency and transport ven ti-

Introduction
This part of IS0 10651 specifies requirements for lung ventilators intended
mainly for home care use but which could be used elsewhere (in hospitals)
for appropriate patients in locations where the use of a ventilator comply-
ing with IS0 10651-l is not required. These devices must meet the defi-
nition of a lung ventilator (to automatically augment or provide ventilation
of the patient’s lungs), but will frequently be used in the home or else-
where by persons with different levels of training. Devices intended solely
to augment the ventilation of spontaneously breathing patients are ex-
cluded from the scope of this part of IS0 10651.
A rationale for the most important requirements is given in annex M.
