Abstract: There is provided a method, apparatus, computer program product and wearable device for monitoring volumetric change of a lung during a breathing cycle by using an electronic signal. The method comprises: receiving by a receiver an electronic signal transmitted from a transmitter, wherein at least part of a path of the signal contours at least part of a chest wall of the lung; determining by the receiver measurements of an attribute of the signal received at the beginning and the end of a time interval during the breathing cycle; calculating by a processor a change in length of the signal path during the time interval based on the measurements of the attribute of the signal received at the beginning and the end of the time interval; and calculating by the processor a volumetric change during the time interval based on the change in signal path length.
