What should be prioritized in the care of a patient with cardiac arrest?

In the case of a patient experiencing cardiac arrest, the most crucial action is the immediate initiation of CPR and activation of the emergency response system. Cardiac arrest results in the cessation of effective blood flow circulation, which quickly leads to the loss of consciousness and cessation of breathing. Without prompt intervention, permanent damage to vital organs, especially the brain, can occur within just a few minutes.

By starting CPR immediately, healthcare providers can help maintain perfusion of blood to the heart and brain, which is vital for the patient's chance of survival. Activation of the emergency response ensures that advanced life support and further medical intervention can be provided as soon as possible, improving the overall prognosis for the patient.

Other aspects of care, such as scheduling follow-up appointments, administering oral medications, or assessing past medical history, are not suitable priorities in the face of a life-threatening situation like cardiac arrest. These actions can only be considered after effective resuscitation efforts are underway to stabilize the patient.
