takes a deep, snoring breath, and his breathing becomes deep and fast for a while, then gradually slower and quieter. I point this pattern out to the family. It is called ‘Cheyne-Stokes’ pattern breathing, and it signifies deep unconsciousness. Towards the end of each cycle of fast-to-slow breathing, there are long gaps between Walter’s breaths. I explain that eventually, during this very gentle phase of his breathing cycle, he will simply breathe out, and then not take another breath. No panic, no rush of pain, nothing spectacular. Only a gentle ending of the cycle of breathing.
