The stethoscope is a 'legacy' item from the complete MSE system and is intended for use in systems which are connected to an intubation manikin and 'Smart Lung'. In this software implementation of the stethoscope, placing the cursor over the red target areas on the thorax and left-clicking turns on or off the heart or breath sounds in the area. The hardware implementation uses a much larger number of RFID tags (implanted inside the manikin) which can be interrogated with an RFID stethoscope and which then broadcast the heart or breath sound appropriate to the region.
