The American Academy of Pediatrics (AAP) currently recommends that infants with documented oxygen desaturation in a car seat should be transported in a car bed. Car beds should overcome the position dependent airway instability. However gastro-esophageal reflux may also occur in the flat position and this could potentially result in significant apnea. The purpose of this study was to define if the term infant is at increased risk of apnea and oxygen desaturation while positioned in a semi-reclined car safety seat when compared to positioning in a car bed.
