Thanks again everyone.
Good phone call with him at 7am this morning. Since then he is washed, shaved, and has seen the doctor who told him he is making REALLY good progress. It was the first time talking to him since he went in that he sounded normal, not out of breath or gasping. No CPAP at all now, just oxygen through the nose cannula. Hopefully it will only be a week or so before he is well enough to come home. He still can't get himself out of bed to sit in a chair yet.
He asked us to drop some other items so we drove over to his place, then to Sainsburys, hospital and onto the seaside a few miles away where we had a lovely walk along the seafront, coffee, then haddock and chips all while looking out over a glorious beach. Brilliant morning.
