Final answer:
Rescuers should change positions every two minutes, when one feels fatigued, or if a more skilled rescuer arrives. Proper technique and hand placement are crucial to avoid injuries while performing CPR.
Explanation:
In two-rescuer CPR, rescuers should change positions during certain circumstances to ensure that fatigue does not compromise the quality of chest compressions, which are crucial for maintaining blood flow. One key moment to rotate is approximately every two minutes or after about five cycles of 30 compressions and two breaths, which aligns with the guidelines for high-quality CPR. Additionally, if one rescuer is feeling fatigued or notices a decrease in the effectiveness of compressions, it is reasonable to switch positions at that point. Lastly, a changeover should also occur if a more skilled or rested rescuer becomes available.
Proper training in CPR is essential, as incorrect technique can cause severe damage to the patient, such as broken ribs or damage to internal organs. The correct hand placement during CPR is on the sternum, specifically between the lines at T4 and T9 vertebrae, to facilitate effective chest compressions and avoid injuring the patient. Training and certification in CPR is widely available, and frequently updating these skills is recommended for both medical personnel and the general public.
