Final answer:
Hands-only CPR is recommended for bystanders primarily because it bypasses the potentially uncomfortable or challenging step of delivering rescue breaths, focusing instead on chest compressions which can be critical in the early stages of responding to a cardiac arrest.
Step-by-step explanation:
One of the main reasons that hands-only CPR is recommended for bystander CPR is that rescuers may be unwilling or untrained to perform rescue breaths. Hands-only CPR is a simplified version of CPR that requires the rescuer to provide chest compressions without doing rescue breaths. This method is particularly effective in the critical first few minutes following a cardiac arrest and individuals are more likely to perform hands-only CPR if they are not comfortable with or trained in delivering rescue breaths.
