Apnea of Prematurity, Central Apnea, Desaturation of Blood, Obstructive Apnea of Newborn, Periodic Breathing
Conditions
Brief summary
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).
Interventions
FiO2 adjusted to keep basal SpO2 at target range of 93-95% for 2 hours
FiO2 adjusted to keep basal SpO2 at target range of 90-92% for 2 hours.
