same machine differences

; ;the first was done on an m series auto c-pap ,the second is done on an m series auto c-pap same exact machine .the two scores are way different though . i find it an interesting case for the need for an auto . as each machine differs ,so would the appropriate setting for that machine. im also gaining momentum toward trying to get rid of those snores via a bi-pap . Does bi-pap treat snoring better

The main thing that's different is your body. No two nights does your body do or sleep the same, too many outside factors that the body adjusts to. Jim
