1. A training system comprising:
- a manikin having an insertion site at which a catheter may be inserted into the manikin;
means positioned at the insertion site for receiving a catheter as it is inserted into the manikin at the insertion site;
means for guiding the catheter along a path from the insertion site;
position sensing means for providing signals from which a location of a tip of the catheter can be determined; and
means for providing an output as a function of the signals from the position sensing means.

Abstract
A computerized training system allows physicians, nurses and other medical professionals to obtain substantial experience in hemodynamic monitoring without need to acquire all that experience with live, critically ill patients. The system simulates the entire process of hemodynamic monitoring, including the physical process of introducing the catheter through an insertion site in a manikin, feeding the catheter through the veins, the heart and into the pulmonary artery, inflating the balloon at the tip of the catheter, and interpreting the measured pressure and other information obtained.
