Medical mannequins are more than classroom tools—they are used in emergency room ultrasound simulators too. Hospitals now create mock drills using full-body mannequins to test their staff in high-pressure situations. These drills reveal weaknesses in procedures, equipment readiness, and team communication. Doctors and nurses practice working as a unit, improving their response time and coordination. Mannequins make these drills feel real, offering valuable experience that traditional learning methods can’t match. Ultimately, this leads to a faster and more efficient healthcare system.
