Episode notes
Shockable Rhythms Offer Best Survival
- VF or pulseless VT offer the greatest chance of survival after cardiac arrest due to their shockable nature.
- Approximately 20% of cardiac arrests present with these rhythms initially, allowing defibrillation a potential for ROSC.
Multiple Mechanisms Behind VF
- VF is not a single uniform event but involves varying mechanisms such as multiple wavelets and mother rotor models.
- These mechanisms influence the propagation and persistence of VF and may differ in early versus sustained VF stages.
Optimize Defibrillation Pad Placement
- Optimize defibrillation by placing pads precisely, trimming excessive chest hair, drying the chest, and avoiding air pockets.
- Take extra seconds during chaos to ensure pads adhere well and maximize current delivery.
