Yes Please My dad is having a lung biopsy today. He has been in the hospital for 33 days and no changes. S.O.B, coughing up blood. Lungs are only working 38%. On Cpap at night and High Flow NC during the day. O2 stats go down to 84/81% when he sits up. They want to do a lung biopsy today. I know they will have to vent him. Is there a chance he will come off the vent? He has COPD, Lung Fiborosis and stage 5 kidney failure. I know it is in Gods hands and his, Plus the Doctors, but I am worried, should this be done? I know it will help give some answers. But scared at the same time. I have faith in the doctors.
