Just ben given a machine on loan which is a godsend for Steve. He has tremendous trouble coughing and when I mentioned this to the physio she arranged for this machine to be delivered. Its a machine which takes air out of the lungs and gives air back to the lungs via a tight fitting mask over the mouth and nose. No oxygen or anything pumped in - all natural. It really works. Thought I would share this with the community as finding anything to assist is wonderful.
