What is a common effect of proper CPR technique?

Proper CPR technique effectively improves blood flow to vital organs, which is crucial during cardiac arrest. When performed correctly, CPR creates artificial circulation by compressing the chest, which helps maintain perfusion to vital organs such as the heart and brain. This is particularly important because the brain and coronary arteries are highly sensitive to prolonged periods of inadequate blood flow, and timely CPR can significantly enhance the chances of survival and recovery.

The other choices reflect outcomes that may not directly result from proper CPR technique. While immediate return of spontaneous circulation can occur in some cases, it is not a guaranteed outcome of CPR and may take multiple cycles or interventions. Reduced risk of airway obstruction is more related to effective airway management rather than CPR itself. Instant stabilization of heart rhythm might occur with defibrillation but is not a direct effect of performing CPR. Thus, improved blood flow to vital organs encapsulates the primary and essential benefit of effective CPR.
