Mannequin-Based Simulations

Mannequin-based simulations use high fidelity simulators, mannequins that breathe, with breath sounds, heart tones, and palpable pulses. In addition, the mannequin has a monitor that can display EKG, pulse oximeter, blood pressure, arterial wave forms, pulmonary artery wave forms, anesthetic gases, etc. Procedures can be performed on the simulators such as bag-mask ventilation, intubation, defibrillation, chest tube placement, cricothyrotomy and others.

Medical students practice on plastic at the Johns Hopkins Sim Center Residents practice surgery on mannequins

Using mannequins in clinical simulations allows future and current physicians to ‘practice on plastic’ first. The reality of mannequin-based simulations allows for virtual feedback using computers that regulate the mannequin's compressors, mimicking pulses and chest raising.These life-like mannequins simulate heart tones and other vital cues that when connected to monitors, provides real-time information to students. By practicing true clinical skills in a safe and regulated environment, future physicians learn permanent and excellent evaluation and treatment techniques.
