Oxygen is clinical solution for Hypoxaemia and there is no alternative medicine other than oxygen. Such condition is often linked with pneumonia. A study estimated that higher number of children (< age of 5) are dying due to pneumonia (infectious disease) than combined with HIV/AIDS and Malaria. In addition, post morbidity conditions in patients with reduced lung capacity require home care and even portable oxygen systems for travel too. COVID-19 exhibited “surge requirement” to its worst case scenarios that can be repeated during long tenured wars, remote border location severity during wars, infectious outbreaks/ pandemics and damage to healthcare infrastructure during hybrid wars. Continuous availability of oxygen in primary healthcare clinics or smaller remote hospitals as well as even in district hospitals become challenging under such conditions. Thus, oxygen availability is essential and oxygen concentrator is one of the important solutions available world wide.
