(A) Example point-of-care ultrasound views that can be obtained during cardiac arrest, including subcostal images (to be obtained during pulse checks) and extracardiac images (which may be obtained alongside active CPR). Also listed (box) are reminders to encourage efficiency and safety. (B) Representative ultrasound images that may be associated with some of the underlying causes of cardiac arrest, organized by the type of shock (cardiogenic, obstructive, or hypovolemic) that may precipitate the arrest.
