What is a common misconception about CPR?

The correct choice highlights a common misconception that CPR must be performed in a specific rhythm. In reality, while it's important to maintain a consistent rate of chest compressions (aiming for around 100 to 120 compressions per minute), the emphasis is on continuous and effective compressions rather than achieving a rhythmic pattern in a strict sense. The focus should be on providing effective chest compressions and rescue breaths if trained to do so, rather than adhering to a particular musical or metrical rhythm. This misconception might lead individuals to hesitate or feel overwhelmed about performing CPR, potentially delaying aid to someone in need.

Other misconceptions include the idea that mouth-to-mouth resuscitation is a necessary component, that CPR is unnecessary if the person is still conscious, or that only trained professionals are capable of performing CPR. These beliefs can prevent timely intervention, which is crucial in emergency situations.
