Hi, I'm sorry to disturb you. I'm interested in respiration events in MESA dataset and have read Montage and sampling rate information. When I observed the raw data (EDF format) using EDFBrowser software, I had some questions and wanted to ask you for help.
Hello,
1) The "Pres" signal was not used when scoring respiratory events. I assume it is a nasal cannula signal that is filtered differently from the "Flow" signal.
2) Most channels have the “Therm” label, there are only 11 EDFs with "Aux_AC". For those 11 studies you can assume that "QuAir=5, Quxflow=5, etc" would be equivalent to studies with "QuAir=5, Quxflow=5, etc" for "Therm".
3) The thermistor signal was used to score apneas.
4) Yes, the example above shows a typical thermistor signal.
