Hi my mom went into the hospital the morning of November 19 for a hysterectomy now she can't breath on her own

She went in on the Monday was in recovery the next 2 day they said she could come home Wednesday but when Wednesday came they told me she bleed out a lot in Sergey and that her blood levels where down so she was going to get 2 bags of blood. So Friday the doctor came in and told us during surgery he nick her Bowles and now there's an infection she was going to need another sergery that day since then she is now on a resptory breathing machine because she can't breath on her own and they also has had to use a defibrillator on her, what can I do about this she might not make it out of the hospital
