What is a proper action when performing compressions alongside ventilation?

When performing compressions alongside ventilation, it is essential to maintain a coordinated approach to maximize the effectiveness of cardiopulmonary resuscitation (CPR). Ventilation should be asynchronous with compressions because this method ensures that oxygen is delivered to the patient even while chest compressions are ongoing.

By allowing compressions to continue uninterrupted, blood flow to vital organs, including the brain and heart, is maintained. Asynchronous ventilation means that breaths are delivered during the relaxation phase of the cardiac cycle, which allows for better gas exchange without compromising circulation.

This approach aligns with the advanced cardiac life support (ACLS) guidelines, which emphasize the importance of high-quality chest compressions in a coordinated rhythm with timely ventilations to optimize patient outcomes during a cardiac arrest scenario. The other options do not support the guidelines for effective CPR implementation.
