In stroke care, new or worsening symptoms signal that the patient isn’t stabilizing and may be deteriorating. Radiating chest or jaw pain with left arm involvement points to an acute coronary syndrome or other cardiac event. In a patient with ongoing stroke symptoms, a fresh cardiac issue can worsen overall perfusion and complicate management, making the stroke heavier and more likely to progress. This kind of new systemic symptom would prompt immediate evaluation and treatment to address both the cardiac problem and the evolving neurologic injury. The other options reflect improvement or no new deficit—sudden improvement in speech, decreased facial droop, and a normal gait—so they don’t indicate progression of the stroke.

The key idea here is chest compression fraction, or the proportion of CPR time spent delivering chest compressions. Higher CCF means more continuous blood flow to the heart and brain, which improves survival chances. The 2020 AHA guidelines emphasize minimizing interruptions and delivering high-quality CPR. When the airway is unprotected, you still aim for a very high CCF by coordinating the team to keep compressions going as much as possible and making ventilation breaths quick and efficient to minimize pauses. The recommended minimum is 80%, so you want the majority of the resuscitation time spent on chest compressions rather than pauses for ventilation. If the CCF falls below this, perfusion decreases, whereas striving for 80% or more keeps perfusion at a higher level.

Recognizing a focal neurological deficit is key. Facial droop reflects weakness of the facial muscles on one side, usually from a brain or nerve pathway disruption caused by a stroke. In someone with sudden neurologic symptoms, this unilateral facial weakness localizes to the brain’s motor areas and is a hallmark sign of an acute cerebrovascular event. Chest pain and shortness of breath point more to cardiac or pulmonary problems, while dizziness is nonspecific and can come from many causes. That contrast makes facial droop the best indicator of stroke here. In practice, assess quickly using the FAST approach: Face drooping, Arm weakness, Speech difficulty, and Time to call emergency services.

Protecting the airway during transport is the priority when dealing with an unresponsive patient who may be having a stroke. The recovery position places the person on their side with the head turned slightly to the side and supported, which keeps the airway open and allows any secretions or vomit to drain away from the airway. Gravity helps prevent the tongue from occluding the airway and reduces the chance of aspiration during movement. Lying flat can allow the tongue or soft tissues to block the airway and increase aspiration risk, while lying prone blocks access to the airway and monitoring. The recovery position is the best choice because it maximizes airway security while you transport.
