Recently after an operation, I was referred to a sleep specialist and was diagnosed with moderate apnoea. After a consultation, it was agreed that I would undertake a control experiment, by oxygen testing my breathing on consecutive nights: one spent with a standard pillow and one without the Patney. The contrast was extraordinary - on the standard pillow, there were between 17 and 18 episodes per hour and with the Patney, a mere 4.8. The latter statistic, being under 5, is not even treated as apnoea. With the use of the pillow, I can avoid more drastic treatments. This is excellent news for me.
