研究概览
简要总结
This is a prospective crossover study to compare the within-subject effect of the two target ranges of arterial oxygen saturation (SpO2), both within the clinically recommended range of 90- 95%. The specific objective of this study to evaluate the impact of targeting SpO2 within 93-95% compared to the 90-92% range on ventilatory stability in premature infants of 23-29 weeks gestational age (GA).
