Observational Study
Efficacy of FiO2 increase during the initial resuscitation of premature infants < 29 weeks: an observational study.
To evaluate the heart rate (HR) and oxygen saturation (SpO2) at 15-second intervals within 60 seconds after incremental increases of fractional inspired oxygen (FiO2) during resuscitation of infants younger than 29 weeks requiring two different forms of ventilatory support. ⋯ The efficacy of FiO2 titration in 0.1-0.2 increments may be attenuated and delayed in extremely preterm infants required PPV during the first 6 minutes of life.
