Studies on the Bcg signal in infants.

In this report, we studied the relationship between respiratory and cardiac rates derived from a modified Bcg and for comparison from the thermistor and the ECG in infants from a new-born baby to a 13-year-old boy. The results with fair correlation coefficients support us in our opinion that this method is worth taking into consideration. Although the number of disturbances is not negligible, this indirect method offers a harmless control of vital parameters in childhood and adolescence. It gives reliable data without any trouble to the patients. In a period of increasing malpractice accusations, it could be of some interest to have a monitoring device working without any direct contact with the patient.
