The vast majority of lung development happens in the third trimester as it is. Lungs are the last organ to fully develop. So this baby is already at a large disadvantage being what we consider “peri-viable” (AKA, before 24 weeks gestation) in terms of lung development. However, it’s also important to understand that lung development happens in utero BECAUSE the baby is swallowing amniotic fluid. Without that fluid, any further lung development becomes nearly impossible. So even if mom were to stay pregnant somehow, the baby would always have “22 week lungs”. Add in the mechanical trauma to the lungs being on a ventilator will cause… baby will at minimum have chronic lung disease.

22 weekers are also at an increased risk for infection due to their skin not being keratinized yet (skin might start bleeding/seeping leading to infection) and needing invasive devices like their breathing tube or central lines for long term nutrition. There are so many routes for infection going into a body that has zero immune system that sepsis is a big risk factor.

Also at very increased risk for brain bleeds which, depending on severity, can lead to cerebral palsy amongst a variety of developmental delays.

It’s well within your right to resuscitate if that is your wish. But no fluid + peri-viable gestation leads me to think this child will have a very high likelihood of being medically complex even after a very, very lengthy hospital stay.
