Yes.
The electrical stimulation will make most of the muscles in the body contract, in which many times will make air move in/out of the lungs past the cords just enough to make noise. Kinda neat to watch and hear it happen.
I have actually had one pt.... when defibrillated... his arms came straight up and hit me ( paddle days ), then they slowly went back to his side ( as the muscles relaxed ).
<sigh> Things like this will be the calls you will always remember, cherish them so one day you can look back and let it bring a smile to your face.
