FoCUS to the Rescue!

Introduction to Rescue Ultrasound

  • In this brief introduction I’ll discuss basic principles of rescue imaging including the shock-based differential diagnosis approach.  
  • Here you can find my rescue echo cheat sheet.  I keep these attached to my echo machines and review them before finalizing my impression about rescue cases.  Feel free to use and distribute!

Hypovolemia vs. Low-Afterload

  • This is the most common and fundamental question we ask when performing POCUS for rescue, and it seems pretty simple, right?  Just because it’s simple doesn’t make it easy!  These two physiologies (not diagnoses) commonly coexist, they’re difficult to distinguish, and we often finish our POCUS evaluation with a healthy uncertainty in this area.  THAT’S OK!  

Dynamic LVOT Obstruction

  • Yeaaaaah, I debate about even including this.  I go back and forth, and I’m still not certain.  Dynamic obstruction is easy even for experts to overlook and it’s very difficult for beginners to diagnose or exclude.  Eh.  But I think it’s such an important physiology to consider, I just have to keep this section in the line-up!
