Compass is still being developed and is effectively in beta. Some content and features may be incomplete, change, or not work as expected.
Content is anchored to trusted sources where available, but Compass has not yet been clinically reviewed. It provides general information rather than medical advice.

- Why does ALS/MND affect breathing during sleep?
Supports this
“Overnight, breathing can become shallower and less effective, so carbon dioxide can build up without the person noticing.”
A review that describes the same sequence: as the breathing muscles weaken, ventilation drops markedly during dreaming sleep, and a rise in carbon dioxide is usually the first thing detectable, before oxygen levels change at all.
