Effective Chest Compressions: How to Determine If CPR Is Working

When performing cardiopulmonary resuscitation (CPR), it is essential to determine whether chest compressions are effective. This can be assessed through two key indicators, as outlined below:

Proper Technique for Effective Chest Compressions

To ensure that chest compressions are effective, the rescuer must first use the correct technique. The proper hand placement is on the lower half of the sternum, at the midpoint of the line connecting the two nipples. For adults, the recommended compression depth is at least 5 centimeters (approximately 2 inches), and the rate should be more than 100 compressions per minute. It is important to maintain a steady, rhythmic pace to maximize blood flow during CPR.

Signs That Chest Compressions Are Working

One of the most reliable indicators of effective chest compressions is the presence of a palpable pulse in the carotid artery located in the neck. Additionally, visible signs that CPR is working may include a return of color to the lips and skin, with the patient appearing more flushed or pink. In some cases, you may observe the pupils constricting or the eyes moving slightly. If the patient begins to show signs of restored heartbeat, such as a return of spontaneous breathing, improved skin tone, and reactive pupils, this suggests that the CPR efforts have been successful.

Conclusion

Recognizing the effectiveness of chest compressions is crucial during CPR. By ensuring correct hand placement, depth, and rate of compressions, and by observing physiological responses such as pulse, skin color, and pupil reaction, rescuers can better assess whether their efforts are making a difference in saving a life.
