When performing CPR on a smaller adult or teenager, what should be adjusted regarding compression technique?

When performing CPR on smaller adults or teenagers, the technique for delivering chest compressions should be adjusted to ensure both effectiveness and safety. Using one hand for compressions is appropriate for individuals of smaller stature, as it allows for the rescuer to exert sufficient force without being overly forceful, which could risk injury.

This method ensures that the compressions are adequate to circulate blood effectively, while also being mindful of the individual’s size. The use of one hand helps the rescuer maintain a proper technique without compromising the force necessary to achieve an adequate compression depth, which is typically at least 2 inches according to CPR guidelines.

The other options suggest adjustments that are not indicated for smaller adults or teenagers. For instance, the compression depth should remain at least 2 inches, and the compression rate should be consistent at about 100 to 120 compressions per minute, ensuring that all victims receive high-quality CPR regardless of their size. Thus, using one hand helps to adapt the rescuer's technique effectively to suit the individual’s size without compromising the quality of care provided.
