Abstract
Crying ventilatory function was measured in 487 infants shortly after birth. Over the following 5 yr 129 infants suffered attacks of pneumonia or bronchitis. Their initial crying ventilatory function was compared with that of the 358 infants who escaped these illnesses. No statistically significant differences were found in crying ventilatory function between these 2 groups of infants. Newborn infants who subsequently suffer attacks of pneumonia or bronchitis apparently do not start life with deficits in their ventilatory function. Crying ventilatory function was measured in 550 infants at their 1st birthday; 70 had suffered attacks of pneumonia or bronchitis by that age and had made a clinical recovery. Their crying ventilatory function showed no consistent difference from the 480 infants who escaped these illnesses. The reasons for the lack of a difference in crying ventilatory function is discussed.
