A simulated lung for use in real time simulated medical procedures comprising
a
positive pressure source of a gas, a vacuum pressure source, a fixed interior volume
vessel having an inlet, an outlet, and a breath passage port, the inlet in communication
with the positive pressure source, and the outlet in communication with the vacuum
pressure source, a first flow valve intermediate the positive pressure source and
the inlet, a second flow valve intermediate the vacuum pressure source and the
outlet, a pressure sensor in communication with the interior volume of the vessel,
and means for continuously evaluating a pressure signal generated by the pressure
sensor to a desired pressure level within the vessel during the breathing cycle
such that a flow of gas entering and exiting the breath passage port of the vessel
is synchronized with a predetermined desired flow rate of breathing during the
breathing cycle. The desired pressure level depends upon any one of i) a time and
event based script, ii) a computer model, iii) or a combination of a time and event
based script and a computer model based on a physiological state of a simulated patient.
