My mother has a pacemaker and had a surgery 14 days ago to get the 3rd something connected to the pacemaker. After the surgergy she could not breath properly and it seems a mistake has been made. During the surgery nervus phrenicus was cut over, as I understand it. She is 75 years and her heart capacity is app. 10-15 %. How long can she live with such a low capacity? And what is the best treatment? As it is now, she is getting oxygen through her nose, but the doctors aim at moving her to another hospital on thursday, if they manage to get her stabil. How afraid shall I be (my sister is at her side now - I am far from her)
