Oxygen Therapy in Neonates
Introduction to Oxygen Therapy
- Insufficient flow rates can lead to carbon dioxide buildup, and temperature and moisture buildup can be problematic, with potential for reduced visibility of the patient, according to the American Journal of Respiratory and Critical Care Medicine guidelines 1
Humidification
- The American Heart Association recommends humidifying oxygen to prevent mucosal drying and thickening of pulmonary secretions, with a strength of evidence based on recommendations from 2010 2, 3
Oxygen Concentration and Saturation Targets
- The American Academy of Pediatrics recommends starting with lower oxygen concentrations (21-30%) rather than higher (60-100%) and titrating based on pulse oximetry, for neonates 4
- Target oxygen saturation should be maintained between 90-95% for most neonates, according to the American Academy of Pediatrics 4
Avoiding Hyperoxia
- The American Heart Association recommends weaning FiO2 for saturations of 100% to avoid hyperoxia while maintaining saturation ≥94%, based on 2010 guidelines 2, 3
Oxygen Delivery Devices
- Nasal Cannula is the most widely used and preferred for stable neonates, but is limited in maximum FiO2 delivery (typically 30-50% depending on flow rate and infant size), as stated by the American Heart Association and Circulation guidelines 3
- Simple Oxygen Masks can provide 30-50% oxygen to spontaneously breathing patients, according to Circulation guidelines 3
- Non-rebreathing Masks can deliver higher concentrations with appropriate flow rates (approximately 15 L/min), as recommended by Circulation guidelines 3
