SCOPER categorization system

Sleep	Cardiovascular	Oximetry	Position	Effort	Respiratory
S₁- Sleep by 3 EEG channels* with EOG and chin EMG	C₁ - More than 1 ECG lead - can derive events	O₁ - Oximetry (finger or ear) with recommended sampling	P₁ - Video or visual position measurement	E₁ - 2 RIP belts	R₁ - Nasal pressure and thermal device
S₂ - Sleep by less than 3 EEG channels* with or without EOG or chin EMG	C₂ - Peripheral arterial tonometry	O_1x - Oximetry (finger or ear) without recommended sampling (per Scoring Manual) or not described	P₂ - Non-visual position measurement	E₂ - 1 RIP belt	R₂ - Nasal pressure
S₃ - Sleep surrogate: eg, actigraphy	C₃ - Standard ECG measure (1 lead)	O₂ - Oximetry with alternative site (eg, forehead)		E₃ - Derived effort (eg, forehead versus pressure)	R₃ - Thermal device
S₄ - Other sleep measure	C₄ - Derived pulse (typically from oximetry)	O₃ - Other oximetry		E₄ - Other effort measure (including piezo belts)	R₄ - End-Tidal CO₂
	C₅ - Other cardiac measure				R₅ - Other respiratory measure

Proper oximetry sampling is defined as 3 s averaging and a minimum of 10 Hz sampling rate (25 Hz desirable)^[1].

EEG: electroencephalography; EOG: electrooculography; EMG: electromyography; ECG: electrocardiography; RIP: respiratory inductance plethysmography.
* 3 EEG channels defined as frontal, central, and occipital.
