Thank you for the response
The part I am currently have trouble understanding is the correlation between my sinus problems and my apnea and whether one affects the other and which way round.
I have my first month checkup at the hospital this week and the technician told me the machine I use and the data it records is too complicated to explain and I should contact the manufacturer if I want more guidance. I am totally appalled at her response and how unhelpful it was.
I am also interested to know how a home sleep study records ahi versus the cpap machine as the later is obviously recording all the events so seems far more efficient at the calculations than the home study
