Dear all,
I would like to have an apnea-hypopnea index that resembles as good as possible the AASM 2012 rules in order to compare results on the SHHS dataset with other data that was scored according to these rules.
The AASM rules take into account all (central and obstructive) apneas, together with hypopneas that have either a desaturation > 3% OR an arousal.
At first I thought that the index ahi_a0h3a was a good fit. But this index only counts apneas with an arousal. Furthermore, the hypopnea counts only take hypopneas into account that have an arousal AND desaturation, while in the description of the index OR is mentioned.
Do you happen to now if another index is available that better fits the AASM criteria? Or should I create my own index, in that case is there a hypopnea count available which includes hypopneas with either an arousal or desaturation?
Thanks for your help, Margot.
