Oxygen delivery to children with hypoxaemia in small hospitals in developing countries.

Oxygen administration is one of the most important modalities of therapy for a patient with hypoxaemia to prevent death. This review summarises the methods of oxygen delivery applicable in small hospitals in developing countries, and evaluates information about their safety and efficacy. The following criteria were considered: cost and availability, efficiency/oxygen concentration achieved, tolerability/comfort of the method, requirement of humidification, demand for nursing care, and safety of the method and complications. In summary, it is concluded that all low-flow methods, i.e., nasopharyngeal catheters, nasal catheters and prongs, are effective in the oxygenation of sick children with severe pneumonia or bronchiolitis. Nasal prongs are the safest method of oxygen delivery, but nasopharyngeal catheters and nasal catheters are more easily available and less expensive. However, if they are used, they need close supervision to avoid serious complications. Nasal prongs are the method of choice for oxygen delivery in small hospitals in developing countries.
