How do you approach weaning respiratory support in established BPD? I am caring for a former 23 week infant now 47 wk CGA. On Fisher Paykel CPAP +12, 21% FiO2, serum bicarbonate 26. No pulmonary hypertension on echo. On Pulmicort and Atrovent. Not having desaturation events. Hx NEC s/p 3 bowel resections, ROP, G4 bilateral IVH with PHH. S/p DART steroids x2. How do you wean from here? We have some team members who are reluctant to wean respiratory support because linear growth is suboptimal, but I feel that is likely due to multiple GI surgeries and periods of NPO and fluid shifts post-op. while not ideal, it doesn't seem like a reason NOT to wean the respiratory support when the baby appears comfortable, is on mostly 21%, and bicarb is acceptable. Would you wean to a certain PEEP and then try high-flow? How fast/slow and how frequently do you wean? how often are you checking labs?
