I am doing this on behalf of my husband who is unable to use a computer. He will be 79 very shortly. In hospital in November and came out on 24 hour oxygen which has recently been reduced to 15+ and dosage lowered. Consultant waiting results of tests to determine IPF or PF. Cannot walk too far without getting short of breath. Would like to try the swimming pool and would be interested to know if people manage this and how. Coughing is also a problem but varies from day to day. Worse at night.
