Abstract: Respiratory problems are one of the most common reasons for neonatal intensive care unit (NICU) admission of newborns. It has been estimated that as much as 29% of late preterm infants develop high respiratory morbidity. To this purpose invasive ventilation is often necessary for their treatment in NICU. These patients usually have underdeveloped respiratory system with deficiencies such as small airway caliber, few collateral airways, compliant chest wall, poor airway stability, and low functional residual capacity. Consequently ventilation control has been subject of considerable research interest. In this paper we propose an algorithm for detection of respiratory depression by predicting the onset of pO2 depressions using intra-arterial pressure measurements and second order statistical properties of these signals. We calculate the average covariance matrix of intra-arterial pressure measurements in the absence of respiratory depression. We then use this matrix as a reference measu re and monitor the changes in the actual covariance matrix measurements. We predict the onset of respiratory depression once the distance is larger than empirically determined threshold. We demonstrate the applicability of our results using a real data set. (More)
