What is the recommended compression to ventilation ratio for adult CPR?

The recommended compression to ventilation ratio for adult CPR is 30 compressions to 2 breaths. This guideline is crucial for effective cardiopulmonary resuscitation as it emphasizes the importance of compressions in maintaining blood flow to vital organs during a cardiac arrest.

In adult CPR, the priority is to deliver high-quality chest compressions that are continuous and at a rate of 100 to 120 compressions per minute. This ratio of 30:2 was established to maximize circulation during the critical initial phase of resuscitation while still providing adequate ventilations when necessary. By performing 30 compressions followed by 2 rescue breaths, rescuers ensure that the victim’s blood is being circulated effectively while also addressing the need for oxygenation.

The other ratios do not align with the current guidelines, which emphasize the importance of maintaining a high frequency of compressions to support blood flow. Although breaths are important, the higher number of compressions in the 30:2 ratio reflects the priority placed on mechanical circulation during CPR.
