I recently got the access of dataset.
I am abale to see the Obstructive Sleep Apnea(OSA) at moonlight using EDF and XML files.
My GOAL is to detect OSA vs Normal Sleep so I am trying to open both EDF & XML files in Python.
So far I am unable to do so, can I get any guidance/help in this regard?
Particularly I am interested in Respiratory or thoracic and abdominal excursions (THOR and ABDO) data.
I presume there are other Python tools to read in XML files, though it will probably be up to you to write code to specifically process/combine/analyze the NSRR files.
Thanks alot for your response, pyEDFlib is helpful, I am able to extract the data. :)
I have another two Questions 1) I´ve read in Gavidia et al (2023)* that The XML file includes annotations for every 30-second sample of sleep stages. Does that 30 seconds include annotation like Normal sleep vs OSA etc?
2) Do we have apnea-hypopnea index (AHI) score in SHHS
*DETECTION OF OBSTRUCTIVE SLEEP APNEA FROM WEARABLE PHYSIOLOGICAL DEVICES
The 30-second epoch sleep staging is separate from the respiratory event scoring. The ScoredEvent sections of the XML files give timestamps and durations of respiratory events (e.g., apnea, hypopnea).
