Oxygen use for preterm infants: factors that may influence clinical decisions surrounding oxygen titration.

Preterm infants in neonatal intensive care units frequently require oxygen therapy. Clinicians are responsible for titrating oxygen to maximize the benefits and minimize the risks of this therapy. Studies have identified various toxic effects of oxygen on the developing tissues of the preterm infant; however, optimal target SpO(2) ranges have not been identified. Current trends in neonatology are focusing on defining optimal oxygen saturation ranges to improve infant outcomes and to decrease complications associated with the oxygen use. Consequently, research-based guidelines are being developed in neonatal intensive care units to guide oxygen administration. As target oxygen saturation ranges are developed, issues regarding health care professional compliance with these ranges have been identified. The specific reasons for this noncompliance have not been widely explored. However, factors such as nursing shortages, staffing issues, and a de-emphasis on staff education surrounding oxygen use have been offered as possible reasons. Understanding factors shaping clinical decision-making about oxygen titration is critical when designing policies and educational programs to change oxygen titration practice and ultimately improve patient outcomes. In this article, the literature outlining the importance of oxygen titration for preterm infants is reviewed. Discussion then focuses on factors that influence clinical decision-making and how these factors may influence decisions surrounding the use of oxygen for preterm infants.
