Answer :
Final answer:
The compression to ventilation ratio for one person performing CPR on victims of all ages is 30:2, placing emphasis on chest compressions. However, proper CPR training is essential.
Explanation:
The compression to ventilation ratio for a lone rescuer giving CPR to victims of all ages is 30:2, this means for every 30 chest compressions, 2 breaths should be given. Providing artificial respiration, however, is often considered to be of secondary importance to the chest compressions, which maintain some oxygenation by forcing blood through the heart into the rest of the body. Proper CPR training is essential to apply these techniques safely and effectively.
