Emergency Medical Minute
Our near daily podcasts move quickly to reflect current events, are inspired by real patient care, and speak to the true nature of what it's like to work in the Emergency Room or Pre-Hospital Setting. Each medical minute is recorded in a real emergency department, by the emergency physician or clinical pharmacist on duty – the ER is our studio and everything is live.
