The sampling rate should be at least two times the highest frequency you expect to record in that channel.
Realistically, the higher the sampling rate the more resolution you will have in the recording. But you do not want it too high as it wastes recording space and slows down the computer in review/scan mode.
Standard clinical sampling rates:
EEG = 256
EOG = 256
Chin, Leg EMG = 256
ECG = 128
Nasal pressure cannula for flow and snore = 128 or 256
Snore microphone = 128 or 256
Respiratory thermistor, belts, CPAP Flow = 32
Oximeter = 8 to 32, depending upon how good an oximeter you have.
CPAP Pressure = 8-32 (depends upon your equipment)
Position sensor = 1
