Nonintrusive Estimation of Apnea-Hypopnea Index

Abstract

New predictors of apnea-hypopnea index were devised by assessing the autonomic dysfunction in obstructive sleep apnea patients. The regression models was developed using the new predictors extracted from the electrocardiographic recordings and the apnea-hypopnea index predictability was validated with the non-intrusively measured piezoelectric recordings
