When performing compressions on adults, especially in cases where the rescuer or the patient has joint conditions, the goal is to provide effective compressions while minimizing strain and injury. The correct alternative hand placement involves placing one hand on the breastbone (sternum), while the second hand supports the first. This technique allows the rescuer to maintain proper alignment and control during compressions, enabling them to generate sufficient force without putting excessive pressure on the joints.

Using this technique, the rescuer can also ensure that the compressions are delivered to the center of the chest, which is crucial for promoting circulation during a cardiac arrest. This hand placement provides a stable base, which is especially beneficial for those who may have difficulty performing compressions with both hands due to discomfort or joint problems. It maintains the effectiveness of each compression while making it easier for the rescuer to continue the lifesaving procedure for an extended period if necessary.

Other approaches, such as using both hands on the abdomen or attempting to use feet for compression, are not standard practices for conducting chest compressions and do not align with the anatomical requirements for effective CPR.
