Ventilatory Responses to Hypercarbia in Infants of Mothers Who Smoke and Misuse Substances

Abstract

The ventilatory response of infants of mothers who smoke and misuse substances and controls to carbon dioxide was assessed at 6-12 weeks and the perinatal period. Infants of mothers who smoke and misuse substances had a dampened response at the peak age of sudden infant death syndrome, greater than in the perinatal period.
