I'll take easy way since case was solved. But obviously check for airway obstruction. None found. Patient is still moving some air but very limited based on description. Attempt to assist breathing with BVM find very restrictive. Unconscious tube him, positive confirmation. Still restrictive to bagging. Only option is give relief. Bilateral chest decompression. Bilat chest decompression still warranted if he has not gone unconscious. He's broke bad and if you do nothing he will be dead by the time you reach the hospital. Since chest is so tight may want to consider multiple needles bilat, in order to get lungs and heart room to work.
