Episode notes
Spinal Stabilization Challenges
- Spinal stabilization is difficult in midair suspension situations and should be addressed after a stable position is achieved.
- Address life-threatening concerns first, such as suspension syndrome and fall injuries.
Suspension Syndrome Mechanisms
- Suspension syndrome involves hemodynamic changes from immobility and orthostatic effects, similar to a parade arrest.
- Prolonged suspension can cause crush syndrome-like effects, potentially leading to cardiac arrest upon reperfusion.
Mitigating Suspension Risks
- If suspended, try to elevate legs or move to promote venous return and prevent blood pooling.
- If possible, self-extricate using rope ascent systems if conscious and capable.
