What device assists in capnography during ACLS?

• A. Nasal cannula
• B. End-tidal CO2 monitor
• C. Pulse oximeter
• D. Defibrillator pads

Answer: (B)

The end-tidal CO2 monitor is crucial in assessing and monitoring a patient’s ventilation status during ACLS. This device measures the concentration of carbon dioxide (CO2) in the exhaled air, providing real-time feedback on the effectiveness of CPR and verifying the placement of an advanced airway like an endotracheal tube. A rise in end-tidal CO2 levels indicates effective chest compressions and is associated with improved chances of return of spontaneous circulation (ROSC). Additionally, it helps in identifying issues such as hypoventilation, patients’ return of spontaneous breathing, or potential complications in ventilated patients.

While other devices mentioned may play roles in patient monitoring, they do not specifically assist in capnography. For instance, a nasal cannula delivers supplemental oxygen but does not provide CO2 readings. A pulse oximeter measures oxygen saturation in the blood but does not give information about carbon dioxide levels or ventilation effectiveness. Defibrillator pads are used for delivering electrical shocks to restore a normal heart rhythm but are unrelated to the measurement of CO2. Therefore, the end-tidal CO2 monitor stands out as the dedicated tool for capnography in ACLS scenarios.
