Hello;my wife is in the ICU on a ventilator,a traech has been done,2 weeks now.this is after surgery for a blood clot that caused her rt leg to have no circulation.the dr s and nurses are baffled by her,as her sedation and pain meds have been lessoned,but she won t wake up much,not today at all.her breathing is rapid,why she is on support.she has been through this before,3x s,has had many surgeries.she had a colonoscopy 2 wks prior to having a problem with her leg.might be time to look outside the box,thanks bill
