What if healthcare learners could see how disease progresses—and explore the consequences of clinical decisions—in a simulated human body?

In this episode of The HealthCast, Phil Zappone sits down with Dr. Aaron Smith, Chief Medical Officer, and Heather Tuttle, Chief Nursing Officer at AI Body, to discuss how digital physiology simulation can connect classroom learning with clinical practice.

They explain how AI Body’s physiology-based models make complex concepts visual and interactive, giving students and practicing clinicians opportunities to explore disease progression and treatment responses. The conversation covers their journeys from bedside care into healthcare technology, the challenges facing new clinicians, and why frontline involvement matters when building tools healthcare teams will actually use.

Topics include:
• Connecting physiology education with clinical decision-making.
• Supporting learner confidence, engagement, and retention.
• Recognizing deterioration before a patient needs rescue.
• Simulating burn injuries and fluid resuscitation for professional education.
• Using constrained large language models with human oversight.
• Building clinician trust through collaboration.
• Preparing for AI’s potential impact on healthcare roles and scopes of practice.
