The settings below represent the standards set at the beginning of the project. There may be a small proportion of studies and signals that do not match these standards exactly. Please review the settings at the individual sleep study level as you proceed with any analyses.
Channel | Sampling rate (Hz) | Sensor type |
---|---|---|
A-Pulse | 1 | Computed Signal derived from photo diodes (reflectance oximetry/transcutaneous monitor) |
A-SpO2 | 1 | Computed Signal derived from photo diodes (reflectance oximetry/transcutaneous monitor) |
A-Snore | 10 | Microphone |
A-Flow | 10 | Nasal Cannula connected to a pressure transducer |
HMov | 10 | Computed signal derived from accelerometers |
HPos | 1 | Computed signal derived from accelerometers |
FVP/A-Effort | 5 | Ares Unicorder Effort-central venous pressure change |
