PATH is implementing a comprehensive approach to increase access to oxygen in low- and middle-income countries, including supporting normative policy change by the World Health Organization (WHO), helping strengthen markets for oxygen concentrators and pulse oximeters, raising awareness about the importance of oxygen through its HO2PE: Oxygen Gives Life campaign, partnering with the United for Oxygen alliance, and developing a suite of evidence-based materials to help advocates and policymakers drive change at the national level.
