By electronically processing these signals it is possible to obtain a signal related to the weighted sum of each individual signal that is proportional to tidal volume. In normal breathing this sum will be greater than zero, and the sum signal can be used to determine when a breath has been taken as well as its relative tidal volume. If the infant’s airway is obstructed, there will be paradoxical movement in the chest and abdomen so that the signals from the chest band will be the inverse of those from the abdominal band.

Sackner JD, Nixon AJ, Davis B, et al Noninvasive measurement of ventilation during exercise using a respiratory inductive plethysmograph.

Thus, by placing wires around an infant’s chest and abdomen in the form of two separate loops, it is possible to determine changes in the cross-sectional area by measuring changes in the inductance of these wires. This is what is done by the inductance plethysmograph. Since wire is stiff and not very compliant, it cannot be used directly to form the loops around the chest and abdomen. However, if it is formed in the shape of a sinusoidal wave, this can be attached to an elastic band such that, as the band is stretched, the sinusoids tend to be stretched out, and they return to their original shape when the band is relaxed.
