Charlie,
This can happen to anyone that has any sort of respiratory augmentation, especially CPAP. It is initiated by receptors on the lungs. When the lungs are stretched beyond a certain point (different for each individual), it sends a message to the respiratory drive center in the brain saying "our lungs are stretched, stop breathing for a bit". This is know as the Hervig Brewer Reflex. When the CPAP is too high, air is trappped in the lungs with each breath. When the lungs reach the Hervig Brewer threshold, one will stop breahting, allowing trapped air to escape, although with CPAP the air escaping is not very effective and after being allowed by the brain to breath again, it only takes a short while until another central event is triggered. traditionally Bilevel pressure is the answer for this problem.
Good Luck
