What common mistakes should be avoided while performing CPR?

The correct answer identifies critical mistakes that can hinder the effectiveness of CPR. Performing CPR requires precise technique to ensure it effectively oxygenates the blood and maintains circulation.

Inadequate depth or rate of compressions can significantly reduce blood flow to vital organs. The recommended depth is at least 2 inches for adults, and the rate should be between 100 to 120 compressions per minute. If these parameters are not met, the chance of survival diminishes.

Failing to allow chest recoil is another vital mistake. It's essential for the chest to fully recoil after each compression, as this allows blood to fill the heart's chambers, which is crucial for effective circulation during the next compression.

Interruptions during compressions, unless necessary for safety or to switch rescuers, should be minimized. Continuous, uninterrupted compressions are most effective for maintaining blood flow to the brain and other vital organs until professional help arrives.

Understanding these common errors is fundamental in CPR training, as avoiding them can make a life-saving difference in emergency situations.
