A suction simulation device includes a suction catheter and a suction unit in fluid communication with the suction catheter. The suction unit includes a reservoir for holding fluid and the suction unit is configured to provide vacuum capability to the suction catheter. The suction simulation device also includes a pump in fluid communication with the suction unit, the pump configured to flow the fluid from the reservoir. The suction simulation device is adapted for use with a manikin comprising an airway. Also disclosed is a suction simulation system and a method of simulating a scenario requiring mechanical ventilation.
