Cardiopulmonary coupling (CPC) analysis is an approach of data extracted from a single channel of ECG, and is highly correlated with the actual respiration. There have been an increasing number of papers evaluating CPC or using CPC as a clinical measurement. It has been recommended, based on several studies, to be a screening tool for sleep disorders, especially sleep related breathing disorders (SDB). Previous studies have suggested that adding oximetry would improve the reliability of clinical evaluation. This study was designed to investigate the consistency rate between CPC sleep spectrogram and Oximetry results on detecting sleep apneas.
CPC can be used for clinical evaluation, such as detecting sleep apneas. It has advantage for screening sleep in pediatric populations.
In addition to its simplicity and cost-effectiveness, the reliable results and acceptability can make CPC practical for clinical evaluation. More and better designed clinical studies are worth exploring in the future.
