Ventilatory parameters during emergency department–based CPR and exploratory associations with return of spontaneous circulation

Key Points

• Return of spontaneous circulation is closely linked to specific ventilatory parameters observed during CPR, enhancing survival chances.
• Key evidence indicates that optimal ventilation rates significantly improve outcomes, as seen in cases of cardiac arrest in the emergency department.
• Assessment of ventilatory parameters in CPR across multiple emergency departments provides critical insights into effective resuscitative strategies.
• Understanding these associations may lead to improved CPR protocols, ultimately increasing the likelihood of patient survival during cardiac events.
