Schematic drawing of the VoluSense Pediatrics (VoluSense, Bergen, Norway) measurement system. Schematic drawing of the VoluSense Pediatrics (VoluSense, Bergen, Norway) measurement system. The supine infant is wearing an elastic vest with conductive elements. An electromagnet positioned above the cot at a precise height generates a weak magnetic field that induces a voltage in the metal wires of the vest. This voltage is proportional to the cross-sectional area of the torso, and will increase and decrease proportionally to the breathing movements of the infant. The system is initially calibrated against an area reference coil positioned at the side of the infant. A computer controls the system during collection and logging of data. Mariann H.L.
