SleepyHead and ResScan Reporting Differently

[psweath]

I'm using SleepyHead v0.9.6 and ResScan 5.1.0.8731.

For the approx. last 6 months period from 9/16/2014 to 3/18/2015 (my first 6 months of CPAP):

SleepyHead reports average AHI = .94 (Obstructive = .36, Hypopnea = .16, Clear Airway = .41),

while ResScan reports average AHI = .6 (Obstructive = .1, Hypopnea = .1, Central = .3).

Why the diff? Is ResScan perhaps including Used Days < 4 hrs? Or even Days not used?

Thank you!
Pete

Welcome to the forum.
The most current version of Sleepyhead is 0.9.8.1-testing and ResScan is 5.3. Several posts, both on this forum and another, indicate that there seems to be an error in ResScan. I don't know if the newer version has addressed this issue. I do know that every poster has been able to substantiate the numbers that Sleepyhead reports which wasn't the case in ResScan.

Take Care!

Thanks very much! Let me update my software packages and re-check!

Just an FYI - I updated both packages to the latest. ResScan shows the exact same results for that 6-month period as before. However, now SleepyHead reports a little differently. See below:

Before software upgrades:
SleepyHead reports average AHI = .94 (Obstructive = .36, Hypopnea = .16, Clear Airway = .41),
while ResScan reports average AHI = .6 (Obstructive = .1, Hypopnea = .1, Central = .3)

After software upgrades:
SleepyHead reports average AHI = 1.05 (Obstructive = .43, Hypopnea = .20, Clear Airway = .40),
while ResScan STILL reports average AHI = .6 (Obstructive = .1, Hypopnea = .1, Central = .3)

Consensus seems to be that SleepyHead is most accurate, so I will go with that!

Thanks for the help,
Pete
