True or False: Securing a patient's airway for ventilation should be prioritized over starting chest compressions during CPR.

Ventilation is important in managing a cardiac arrest, but it should not take precedence over initiating chest compressions during CPR. The rationale behind this prioritization lies in the physiological effects of cardiopulmonary resuscitation.

During cardiac arrest, blood circulation is critically compromised, which means that every moment without effective chest compressions significantly decreases the chances of survival. Chest compressions help to manually circulate blood, delivering oxygen to vital organs such as the heart and brain. This circulation is crucial in maintaining some degree of perfusion until advanced medical help can arrive.

While establishing a secure airway and providing ventilation are important components of CPR, chest compressions must be prioritized to maintain blood flow and oxygen delivery. Once effective chest compressions are underway, rescuers can then focus on airway management and ventilation. In summary, immediate chest compressions are essential to sustain life during cardiac arrest before expanding efforts to achieve optimal ventilation through securing the airway.
