What is the compression-to-breath ratio for adult CPR?

The compression-to-breath ratio for adult CPR is 30 compressions to 2 breaths. This guideline is grounded in evidence-based practices that emphasize a balance between chest compressions and rescue breaths to optimize blood flow and oxygen delivery during cardiac arrest situations.

In adult CPR, high-quality chest compressions are paramount, as they maintain circulation and help preserve vital organ function until emergency medical services can take over. The 30:2 ratio was established to ensure that participants provide a sufficient number of compressions to circulate blood effectively while also delivering adequate breaths to oxygenate the blood.

This approach allows for a continuous and effective cycle of compressions with minimal interruptions for breaths, thereby maximizing the potential for survival. Other ratios do not conform to the current guidelines for adult victims undergoing CPR, making it essential to stick to the established 30 compressions followed by 2 breaths during resuscitation efforts.
