The capnography tracing is an excellent tool that gives us insight into cellular metabolism, perfusion, and ventilation.  This can yield vital information in multiple critical patient care decision processes.  Join Dr. Patrick and Dr. Dickson as they walk through some ETCO2 interpretation basics.  We are limited on the amount of objective information available during prehospital care, don’t ignore this vital piece of our puzzle.

Episode 88 - End Tidal Capnography - Back To The Basics

The MCHD Paramedic Podcast is a place for prehospital providers to discuss best practices and offer clinical insights relevant to our daily practice. MCHD Medical Directors Dr. Robert Dickson and  Dr. Casey Patrick invite you to explore the many aspects of prehospital care. Along the way you can expect guest appearances by some of the brightest minds that influence modern EMS.

Science

The podcast crew is joined by a special guest, Dr. Andrew Partain, an EMS Fellow from UTSW in Dallas.  We will dissect his recent data surrounding ketamine-only intubation from MedStar in Fort Worth. This is not just another boring data rehash. There are some vital and applicable pearls that must be applied to the world of prehospital airway management.

Episode 167 - Ketamine Only Intubations With Dr. Andrew Partain

Applied EKG interpretation is often a difficult task in EMS and emergency medicine education. Getting bogged down in minutiae can obscure the patient. While an understanding of EKG foundational physiology is an absolute must, consideration of how to combine the 12-lead and patient presentation is vital as well. Join the podcast crew as they start at the end with the killer/"can't miss" EKG patterns and combine those with common chief complaints. Hopefully, this framework will click for you.

Episode 166 - The MCHD EKG Manifesto - Part 1

We've spent countless hours (rightfully so) discussing ischemic stroke management over the past several years. Sometimes, the other 20% of strokes, the hemorrhagic version, can get neglected. No, we don't have stroke-mobiles at MCHD to diagnose an ICH in the field, but there are some patient care keys to emphasize for EMS when we suspect non-traumatic, acute intracranial bleeding.

Episode 165 - Intracerebral Hemorrhage

MCHD's POCUS program has definitely involved both forward progress and lessons learned. In this episode, we'll discuss some of the reasons POCUS can be a game changer in the prehospital setting. However, unintended consequences do exist. We've begun to make the move to utilizing carotid ultrasound in OHCA, and we'll tell you exactly why.

Episode 164 - EMS HOCUS POCUS

MCHD paramedic Wes Hall joins the podcast crew to discuss a recent seemingly mundane back pain call. Please listen to find out how avoidance of premature closure, a thorough exam, and professional patient advocacy led to an excellent outcome in a SCARY case.
