Q: Can we submit fresh & supplementary evidence to USCIS for expeditious

My wife ( a U.S Citizen) has petition i-130 for me since, 0ctober, 2018. She applied in February, 2019 to expedite the processing and till now it's not yet approved. My wife is asthmatic and also nursing our four months old baby. 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?
