The roller coaster that Dad is on continues. He was quite alert when I got to the hospital and we chatted but quite quickly he became very drowsy. The doctor came and did more blood tests, and it confirmed the consultants view earlier in the week that once he stops using the pressurized mask he will begin to decline, his lungs will gradually begin to fade and then stop.
(The photo is of a boat on the river on the walk to the hospital, I take some photos each day to share with Dad when I get there).
