Can we submit fresh supplementary evidence to USCIS for an expeditious processing of an I-130 petition?

Question Details: My wife, a U.S citizen, has petitioned for an I-130 for me 8 months ago. She applied 4 months ago to expedite the processing and until now it's not yet approved. My wife is asthmatic and also nursing our infant. At the time of this messsage, she's admitted on an emergency, with a life support machine to control her asthma attack. Can we send this as an emergency and evidence of a life threatening asthma with medical or doctor's approval?
