Mum is just recovering from her first bad bout of pneumonia. In hospital we were told that she should sleep with the bed head at a slight angle but now she is home, dad insists she should be flat because she will be more comfortable. Mum has a hospital bed and when she is flat, seems to cough more which does eventually ease. When at an angle, she slips down the bed and almost 'crumples' up. This then causes her some distress. Can anyone suggest anything please?
