The FiO2 weaning protocol for the OXR group is described elsewhere (7). PIP was adjusted to maintain PaCO2 of 35 to 50 mm Hg and pH of 7.35 to 7.45. PIP was weaned aggressively to avoid overdistension of the lung based on chest movement and PaCO2. Hypotension (mean blood pressure Ͻ...

In children, start nasal cannula at 1-2 l/min or 0.5 l/min in young infants. If critically ill, higher FiO2 can be delivered via nasopharyngeal catheter at 1-2 l/min or face mask with reservoir bag (10-15 l/min). Facemasks with reservoir bags should be used for high-flow oxyge...

In the data published by Wettstein and colleagues a pharyngeal FiO2 of 0.30 to 0.38 can be measured at a COT flow rate of 2 L/min. However, also FiO2 of 31.11 ± 7.63% during HFOT was measured with higher flow rates and applying an air/oxygen mixture. Higher flow rates might ...
on the flow rate since each inspiration entrains a mixture of ambient room air along with the supplemental oxygen provided by the cylinder. Typically, each variation in flow by 1 L/min yields a 4% change in oxygen concentration of the gas mixture (Fraction of inspired oxygen or ...
PbO2 level was dependent on the fraction of inspired O2, and the response to oxygen was more pronounced after a 9 vs. 12 min CA. After a 12 min CA, PbO2 was modestly affected by blood pressure augmentation using epinephrine in the thalamus but not in the cortex. Conclusion: After ...
Conclusions: A critical threshold of FiO2 affecting angio- genesis exists in immature lungs. Exposure of preterm lungs to >40% inspired O2, even for 2 h, may result in abnormal expres- sion of biomarkers regulating lung angiogenesis. Bronchopulmonary dysplasia (BPD), a chronic lung dis- ease...
