EP48 'The Science of Prone Restraint Deaths' with Dr. Geoffrey Desmoulin

Summary:In this episode of Trainer's Bullpen, host Chris Butler speaks with Dr. Geoffrey Desmoulin about the critical research on prone restraint techniques in law enforcement.They discuss the conflicting views on the safety of these techniques, the physiological risks involved, and the implications of the Bronstein case, which serves as a cautionary tale for law enforcement practices. The conversation emphasizes the importance of understanding the biomechanics and physiology behind restraint techniques, particularly the role of CO2 buildup in medicalrisks. In this conversation, Dr. Desmoulin discusses eight critical risk factors for sudden death in prone restraint cases. The discussion also highlights the importance of understanding the physiological responses duringrestraint and offers strategies for law enforcement to mitigate risks associated with respiratory compromise.Takeaways:• Physiological effects of prone restraint can lead to serious medical risks.• The recent Bronstein case highlights the dangers of prolonged prone restraint.• Communication of medical risks is crucial for law enforcement training.• The urgency of repositioning subjects in restraint is critical.• Biomechanics play a significant role in understanding restraint techniques.• Training should incorporate findings from recent research on restraint risks. Obesity increases pressure on lungs and reduces tidal volume.• Drugs like meth and opioids disrupt carbon dioxide regulation.• Anxiety can lead to hyperventilation and increased airway resistance.• Downward force during restraint can compress thoracic vessels.• Time is a critical factor in managing respiratory risks.• Reducing the duration of struggles can minimize health risks.• Research should focus on dynamic immobilization scenarios.Listeners should check out the online courses available at GTD Scientific https://gtdscientific.com/
