I am a new critical care nurse. I am taking care of my first "brain dead" patient. She isn't completely brain dead, she responds to painful stimuli, etc. I guess you could say she is a "vegetable".The nurse giving me report said she had a "neuro yawn". And yes, my patient does yawn... but what exactly is a neuro yawn? Anyone know? Or is it just like a habit or reflex to something?Thanks!!
