Human Patient Simulator

The Human Patient Simulator (HPS) system is produced by CAE Healthcare, and consists of a manikin and control rack. The manikin is a full sized lifelike body (adult or pediatric) whose pulmonary, cardiovascular and other systems can respond automatically to a user's interventions and the environment. The control rack contains the physiologic and pharmacologic modeling programs and some of the simulated components.

The Center has two HPS adult manikins, one PediaSim pediatric manikin and two control racks. They can be used for instructor-led teaching, where the patient's condition is known ahead of time, for those starting out their healthcare training.  As the learner advances, the manikin can be used for learning and practicing diagnosis and treatment, as well as teamwork training.

Standard patient monitors and ventilators are used to examine EKGs, blood pressures, exhaled carbon dioxide, airway pressures and oxygen saturation. Arterial, pulmonary arterial and central venous pressures are displayed on the patient monitor.  Pulmonary artery catheter insertion at each critical point can be simulated through the computer and measurements can be displayed as the catheter progresses, including wedge and cardiac output.

Users do physical exams, airway manipulation, defibrillation / cardioversion, pharmacologic interventions, and trauma procedures. Physical responses include heart and lung sounds, pulses, and real gas exchange. Real time blood gases can be read from the monitor and given to the trainees. Brain function is assessed by checking pupil size and reactivity to light. Consciousness is demonstrated by blinking or closing the eyelids.
