My son was born 3 months premature 16 years ago. In US hospitals, insertion of vent tubes and other things like this when a baby is first born is handled by specialized technicians. They have a lot of training like nurses do, but they aren't technically nurses. They are called "respiratory technicians". Along with the nurses, they are EXPERTS at doing these procedures on tiny infants. They practice on dummies constantly. I spoke to a few (one of whom saved my son's life) over a period of weeks while my son was in the Neonatal Intensive Care Unit at the hospital in North Carolina he was born in.
Just stating this, because something that I learned from British parents is that NHS hospitals, while excelling in providing affordable care for general issues, are lacking in highly trained specialists who can insert a breathing tube in an infant in literally seconds due to having practiced it obsessively for years. NHS NICUs also lag behind American NICUs in having the latest equipment. The tradeoff of course is that American NICUs are orders of magnitude more expensive, and that is a very important point to emphasize.
