WHO-UNICEF technical specifications and guidance for oxygen therapy devices

The purpose of this interagency publication is to provide harmonized product specifications for a wide range of products for delivering basic oxygen therapy, and to provide guidance on the selection, procurement, use and maintenance of these products. The specifications and technical guidance are intended to support health facility administrators, clinical decision-makers, procurement officers, planning officers, biomedical engineers, infrastructure engineers and policy-makers to select, procure, use and maintain appropriate oxygen therapy system equipment, especially in low- and middle-income countries. This document may also be of interest to health care workers, academics/researchers, development agencies, nongovernmental organizations (NGOs), device manufacturers, regulators and others involved in planning oxygen systems in low-resource settings.
