Oxygen desaturation of premature newborns in car seats was first reported by Willet in 1986. In response to that study, the American Academy of Pediatrics (AAP) recommended in 1991 that infants <37 weeks’ gestation be monitored for oxygen desaturation and bradycardia in their car seat before discharge. The most recent AAP statement on this issue identifies other infants who are ≥37 weeks and who may be at risk for this problem as potential candidates for car seat testing. Although term low birth weight newborns are not specifically mentioned in that statement, they would be logical candidates for inclusion given the presumed mechanism of desaturation in these devices (physical-mechanical mismatch) as well as case reports of desaturation in some low birth weight newborns. The current report by Davis provides the results of the first large-scale study of car seat testing in term low birth weight newborns....
