AHI measures how many times an hour breathing is stopped or halted for 10 seconds or more. Normal sleep is < 5 times per hour.
My sleep test measurement was 45.1 on 12 April 2023. I now use a Lowenstein prisma SMART max CPAP to regulate my breathing while sleeping and most nights the reading is less than 5. I’ve noticed higher energy levels and better cognition. There was one day at work not long after I began treatment where I thought, “Why is everyone else thinking so slowly today?”
