Very good presentation! As a anaesthetist with experience in neonatal and premature anaeshesia my question is: why don‘t you use a anaesthesia maschine like the Dräger Primus which also provides capnography? In our institution (university setting) we mostly use a cMac videolaryngoscope. PrcedurevStaff: 1-2 anesthetist plus 1-2 RN for maximum safty!
I'm not a fan. Ventilation and pH can be adequately assessed from a vbg and oxygenation via SpO2. I don't really care about PaO2 levels enough to access a femoral artery.
Most likely you need to withdraw the laryngoscope blade. The most common error in premies is to insert the blade too far. One other tip is to quickly wipe the tongue once with a gauze. It keeps the blade from slipping and losing sight of the cords.
