May inform normative autonomic profiles in young infants; extends developmental physiology but leaves open clinical translation.
How do cardiac-rate changes in response to abdominal air-stream stimulation mature in normal infants over the first 5 months of life?
Significant maturational changes in cardiac autonomic control mechanisms occur in the first months of life in human infants.
Upton et al. (1966) studied this question.
