EMT Chapter 26-MCIT-F3-2213 | The Impaired Limb:  This course on critical fracture management is centred around the fact that not all fractures are the same. For EMTs knowing the difference can be the margin between life and death. This five lesson course challenges you to think beyond broken bones and recognize the systemic life threats that major fractures can create. This course builds a complete clinical frame work from first contact to though hospital handoff

The lessons covered are

• Lesson 1: X-ABC & High-Stakes Fracture Recognition
• Lesson 2: Neurovascular Assessment Mastery
• Lesson 3: Critical Fracture Differentiation & The 6 P’s
• Lesson 4: The One-Attempt Rule – Realignment & Traction Splinting
• Lesson 5: Comprehensive Splinting, Pelvic Stabilization & Patient-Centered Care

Excerpt from EMT Chapter 26-MCIT-F3-2213 | The Impaired Limb

Let’s talk about recognizing when a fracture is causing your patient to bleed into shock. This is where good assessment skills save lives. You need to be able to recognize hemorrhagic shock early, when you can still do something about it.​

Early shock also known as compensated shock—shows up as tachycardia and anxiety. The patient’s heart rate is elevated because they’re trying to maintain blood pressure despite losing volume. They might seem restless, anxious, or agitated. Their skin starts to get pale and cool as the body shunts blood away from the skin to vital organs. You might notice they’re diaphoretic even though they’re not hot.​

As shock progresses to decompensated shock, you see hypotension. That’s a late sign, folks. By the time blood pressure drops, your patient has lost significant blood volume—often 30 to 40% or more. You’ll see altered mental status, weak or thready pulses, and potentially no radial pulse at all. Narrow pulse pressure. This is where systolic and diastolic are close together, like 90 over 70—is a red flag.​

Here’s the key: if your patient has a mechanism for major fractures AND signs of shock, assume hemorrhage from those fractures until proven otherwise. Don’t wait for obvious external bleeding. Internal bleeding from pelvic or femur fractures can cause shock just as quickly as external hemorrhage, you just can’t see it happening.​
