Claim 19:
20. A medical air leak modeling method, comprising:
circulating fluid between a first liquid-tight and air-tight chamber and a second liquid-tight and air-tight chamber, the first chamber having a lung therein that is immersed in liquid;
sensing with a sensor a liquid fill level in the second chamber;
in response to the sensor sensing a threshold amount of change in the fill level, activating a peristaltic pump to cause the pump to pump liquid from the first chamber to the second chamber; and
using an amount of rotation of the peristaltic pump in pumping the air from the first chamber to the second chamber to determine an amount of air that leaked from the lung during the circulation of fluid.
