Final answer:
Recent changes to CPR emphasize chest compression depth and rate, prioritize compressions over artificial respiration, and underscore the need for continuous performance until professional intervention. Proper training is crucial to avoid serious injuries during CPR.
Step-by-step explanation:
The question asks about three key changes to Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care (ECC). When discussing recent modifications, it is essential to know that CPR techniques are constantly being refined based on new medical research and consensus among healthcare professionals. However, the exact nature of these '3 key changes' will depend on the time frame being referred to. Generally, updates have emphasized the importance of chest compressions over artificial respiration, the specific depth, and rate of compressions, and the use of automated external defibrillators (AEDs). According to the provided reference material, one noteworthy change is that current standards for performing CPR include compressing the chest at least 5 cm deep at a rate of 100 compressions per minute. This rate can be remembered by timing compressions to the beat of the song 'Staying Alive' by the Bee Gees. It has also shifted towards highlighting the necessity of high-quality chest compressions over artificial respiration and emphasized the continued performance of CPR until spontaneous contraction resumes or until a medical professional declares the individual dead. Proper training in CPR is crucial as improper technique can cause serious injuries like broken ribs or damage to internal organs.
