The algorithm orders. Physiology corrects.
No, the point is not “never use adrenaline”.
The point is that in a monitored arrest, we shouldn't resuscitate with our eyes closed.
If you give a dose and the EtCO₂ doesn't change, the waveform doesn't improve, and perfusion still doesn't appear, the monitor is already telling you something:
repeat less by reflex and think more about mechanism, CPR quality, and reversible cause.
In the operating room, when you have capnography, plethysmography, and sometimes even an arterial line (AL), ignoring physiology to just follow the clock can turn the algorithm into mere window dressing.
CPR is not about “following steps”. It's about moving blood.
Comment PHYSIOLOGY and I'll send you a summary of how to monitor EtCO₂ during CPR.
