Watchpat vs Wellue disagreement?

[lisaistired]

As it relates to correlation with cpap data one has to be very careful to acknowledge the lag time between a respiratory event and changes in blood saturation levels. 
A complete apneic event may take as long as 30 seconds to be evidenced in the atrial blood saturation.

Makes sense thanks -- in that case it sounds like either the watchpat or the wellue oximetry data must be incorrect. It's hard for me to tell how long the watchpat desat spikes last. It sounds like if they are < 30s or so they must be incorrect. 
I'm curious if it is possible to get raw data from the watchpat to actually check this.
