Dr. John Croushorn - Compression Works (RideAlong Interview)
In this special interview episode of the RideAlong: EMT School Podcast, we’re joined by Dr. John Croushorn, Emergency Medicine Physician, Founder and Chief Medical Officer of Compression Works, and co-inventor of the AAJT-S.
Dr. Croushorn sits down with us to discuss the AAJT-S (Abdominal Aortic and Junctional Tourniquet – Stabilized) — what it is, why it was developed, and where it fits into the management of severe, life-threatening hemorrhage when standard extremity tourniquets aren’t enough. We break down junctional and truncal bleeding, device indications, physiologic effects, and the realities of deploying advanced hemorrhage control tools in high-stress environments.
The conversation also explores how devices like the AAJT-S translate from military and tactical medicine into civilian EMS, the challenges of training and decision-making around low-frequency / high-consequence tools, and what EMTs and paramedics should understand about hemorrhage control beyond “tourniquet goes high and tight.”
This episode is an honest, practical discussion about capability, limitations, and clinical judgment — and what it actually looks like when advanced bleeding control meets the real world.
