In the context of cardiac arrest, what is one key reason to open the airway immediately?

Opening the airway immediately during a cardiac arrest is crucial to ensure adequate ventilation and oxygenation. When a patient is in cardiac arrest, their heart is not pumping effectively, leading to a lack of blood flow and oxygen delivery to vital organs, including the brain. By opening the airway, emergency responders can facilitate the delivery of oxygen directly into the lungs, allowing for artificial ventilation if necessary.

This action helps to prevent hypoxia (lack of oxygen) and supports the patient’s chance of survival until more advanced medical interventions can be performed. Without proper ventilation and oxygenation, brain damage and other organ failures can occur rapidly, making this step a critical component of resuscitation efforts.
