What is a Manikin?

Manikins, also known as patient simulators, are anatomically accurate models used in healthcare simulation to represent human patients for training and educational purposes. These lifelike models range from simple task trainers to high-fidelity simulators capable of replicating various physiological functions and clinical scenarios. In healthcare simulation, manikins serve as versatile tools for hands-on practice, skill development, and competency assessment across a wide range of medical disciplines and procedures.

Difference Between Manikins and Mannequins

While the terms "manikin" and "mannequin" are often used interchangeably, there is a distinction between the two:

  • Manikins: Manikins are anatomically accurate models specifically designed for medical training and simulation purposes. These models are equipped with features such as realistic airways, interchangeable clinical features, and physiological responses to simulate patient conditions and responses accurately during simulation scenarios. Manikins are used extensively in healthcare education for clinical skills training, scenario-based learning, and team training exercises.

  • Mannequins: Mannequins, on the other hand, are typically used in retail settings and the fashion industry for displaying clothing and accessories. While mannequins may resemble human figures, they are not anatomically accurate and do not possess the functional capabilities or physiological responses of manikins used in healthcare simulation. In the context of healthcare simulation, the term "manikin" is preferred to distinguish these models from retail mannequins.

Levels of Fidelity

Manikins vary in fidelity, which refers to the degree of realism and complexity in their anatomical features, physiological functions, and interactive capabilities. The concept of fidelity levels in manikins is more of a guideline than a strict rule due to the diverse nature of simulation scenarios and varying learner needs. Modern manikins often blend features from multiple fidelity levels to meet specific training requirements. Educators should select manikins based on learning objectives, scenario complexity, and available resources to ensure an effective learning experience. The levels of fidelity commonly used in healthcare simulation include:

Low-Fidelity Manikins

Low-fidelity manikins are basic models designed for task-specific training and skill acquisition. These simulators typically feature simplified anatomical structures and limited functionality, making them suitable for introductory training and basic procedural skills practice. Low-fidelity manikins may include:

  • Partial Anatomy: Basic anatomical structures relevant to specific training objectives, such as airways, chest cavities, or limbs.
  • Limited Functionality: Simple features such as movable joints, removable parts, or basic physiological responses (e.g., chest rise and fall).
  • Cost-Effectiveness: Affordable and easy to maintain, making them ideal for introductory training programs or resource-constrained settings.

Medium-Fidelity Manikins

Medium-fidelity manikins offer a higher level of realism and functionality compared to low-fidelity models. These simulators provide learners with more immersive training experiences and greater flexibility for practicing a wider range of clinical skills and procedures. Medium-fidelity manikins may include:

  • Anatomical Accuracy: More detailed anatomical structures and physiological features that closely resemble human anatomy and physiology.
  • Interchangeable Features: Replaceable parts or interchangeable modules to simulate different patient conditions or scenarios (e.g., wound kits, surgical inserts).
  • Basic Physiological Responses: Simulated vital signs, palpable pulses, or audible breath sounds to enhance realism during patient assessments and interventions.

High-Fidelity Manikins

High-fidelity manikins are advanced models equipped with sophisticated technology and interactive features to replicate human anatomy, physiology, and pathophysiology accurately. These state-of-the-art simulators offer the most realistic and immersive training experiences, allowing learners to practice complex clinical skills and critical decision-making in dynamic simulation scenarios. High-fidelity manikins may include:

  • Realistic Anatomy: Highly detailed anatomical structures, including lifelike skin texture, palpable landmarks, and internal organs with realistic haptic feedback.
  • Dynamic Physiology: Simulated physiological responses that mimic human vital signs, cardiac rhythms, respiratory patterns, and neurological assessments in real-time.
  • Interactive Features: Advanced features such as voice recognition, wireless communication, and remote control capabilities to enhance scenario realism and instructor control during simulations.

Applications in Healthcare Simulation

Manikins have diverse applications in healthcare simulation, including clinical skills training, scenario-based learning, and team training exercises. These models provide learners with realistic and immersive training experiences that enhance clinical competencies, improve patient outcomes, and promote quality and safety in healthcare delivery.
