DHO First Aid Practice Test

The correct ratio of compressions to breaths in CPR for adults is 30 compressions to 2 breaths. This specific ratio is based on guidelines established by organizations like the American Heart Association, which recommend this ratio for adult victims of cardiac arrest. The emphasis on high-quality chest compressions is critical, as they help maintain blood flow to vital organs, particularly the brain and heart, during cardiac arrest. Providing two breaths after every thirty compressions allows for the necessary oxygenation of the lungs, which is vital for successful resuscitation. This approach ensures that compressions remain the primary focus, as they are the most crucial part of CPR for survival.
