Abstract: A method and apparatus for reducing respiratory abnormalities in infants and the incidence of crib death by providing a flow of room air to a sleeping infant's environment to stimulate breathing. In a preferred embodiment of the invention, room air is delivered into a crib through an air plenum that is removably attached to the vertical bars of a crib and positioned within 1 cm to 20 cm of the infant's mouth, nose, larynx and trachea. The flow of room air from the air plenum safely assists the respiration of an infant with inadequate shallow end tidal volume, decreases rebreathing of expired carbon dioxide from the nose, mouth, oral cavity and trachea, prevents pockets of increasing carbon dioxide from developing within the cushions and beddings surrounding the infant, and decreases the likelihood of overheating and other conditions associated with sudden infant death syndrome, apnea syndromes and hypoventilation.
