Description détaillée
Pneumonia is the leading infectious cause of death among children less than 5 years of age. Hypoxemia is a major fatal complication of pneumonia, and the risk of death increases with increasing severity of hypoxemia. Improving oxygen delivery and extending oxygen supplies to children with hypoxemia due to severe pneumonia could reduce mortality in resource-limited settings.
Global Good has developed a low cost oxygen mask (nasal reservoir cannula) to more efficiently deliver oxygen to the pediatric patient by increasing dead space to recapture a portion of expelled oxygen using the spatial distribution of the nasal reservoir cannula volume and length of surface seal. This nasal reservoir cannula fits over a standard nasal cannula (also termed prong). The system is designed to reduce administered oxygen to deliver an equal or higher fraction of inspired oxygen (FiO2) per oxygen delivered (L/min) compared with a standard nasal cannula alone.

Intervention / Traitement |
|---|---|
|
Expérimental: Group A
Each patient will receive oxygen for 1 hour using a novel mask (nasal reservoir cannula) plus standard nasal cannula (Period 1), followed by a 1-hour period of continued use of the standard nasal cannula alone (Period 2).
|
The experimental oxygen mask (nasal reservoir cannula) fits over a standard nasal cannula.
The system is designed to reduce administered oxygen to deliver an equal or higher fraction of inspired oxygen (FiO2) per oxygen delivered (L/min) compared with a standard nasal cannula alone.

Expérimental: Group B
Each patient will receive oxygen for 1 hour using a standard nasal cannula alone (Period 1), followed by a 1-hour period of continued use of the novel mask (nasal reservoir cannula) plus standard nasal cannula (Period 2).
