Objectives:
To determine the utility of a new operator-independent, automated measure of sleep physiology based on cardiopulmonary coupling (CPC) analysis in subjects with primary insomnia vs. good sleepers.

Conclusions:
Primary insomnia subjects have a marked worsening of sleep quality on the adaptation night, which is well captured by both conventional and ECG-derived sleep spectrogram techniques. 

Practical Significance:
The operator-independent, automated measure of sleep physiology demonstrated functionality to differentiate and objectively quantify sleep quality.
