๐ฉโ๐ You're 6 minutes into CPR after a building collapse.
Your arms are burning, you're drenched in sweat, and you're not done yet.

A recent article in Prehospital Emergency Care took a hard look at a study evaluating CPR performance during simulated disaster rescues and offered some sharp (and well-deserved) critiques
Hereโs what you need to know โฌ๏ธ
The original study examined rescuers performing CPR during simulated post-earthquake conditions.
Rescuers did 5 uninterrupted CPR cycles (~2.5โ3 min) per person before switching.
CPR โqualityโ was assessed based only on compression depth (green light on the simulator).
Key Concerns Raised by Imamoglu et al.:
โ No chest compression fraction (CCF) reported, even though we know this is a strong predictor of survival. Guidelines recommend CCF >80%.
โ Ventilation measurement was vague โ no detail on volume, pressure, or visual confirmation of chest rise.
โ Rescuer switches every 2.5โ3 min, instead of the recommended 2 min
โ CPR quality was based solely on compression depth, but no data on recoil, rate, or no-flow time
โ Gender distribution was inconsistent between methods and randomization, raising reproducibility concerns.
๐๐ก๐ฒ ๐๐ก๐ข๐ฌ ๐๐๐ญ๐ญ๐๐ซ๐ฌ ๐๐จ๐ซ ๐๐๐:
Fatigue during prolonged CPR, especially in disaster settings, can rapidly degrade performance.
Simply counting compressions isnโt enough. Metrics like rate, recoil, ventilation quality, and CCF must be tracked.
Using feedback-enabled manikins can help simulate real-world stress and improve future training
Bottom Line:๏ฟฝHigh-stress, high-fatigue scenarios demand more than just effort. They demand data-driven, guideline-based performance.
