Abstract
Patients with cerebral palsy suffer from permanent movement disorder, and a nurse usually performs their tracheal aspiration where a tube must be inserted into the patient’s trachea. The tube insertion procedure must be performed quickly and carefully in order for the patient not to experience significant pain, anxiety, and even tracheal bleeding that would cause fear for the patient. To master such skill, many training opportunities should be provided for the novice nurses. Therefore, a training simulator is needed that could mimic the real situation of the procedure to provide an accurate and realistic feedback to the novice nurses. To realize that goal, we have developed a simulator that provides a head mannequin with the pain sensor attached and can project computer-generated patient’s facial expressions onto the mannequin face using projection mapping. The expression can change in conjunction with pain intensity the patient would receive due to the sputum blockage in the trachea and due to the hard contact of the tube tip with the trachea. The effectiveness of the projection mapping in the simulator is evaluated by comparing how fast trained and novice nurses finish the procedure when the facial expression of the pain is simulated or not.
