Which device is a monitor and defibrillator used for cardiac arrest?

The LIFEPACK 15 is a crucial device utilized in emergency medical situations, particularly for cardiac arrest. This multifunctional device acts as both a monitor and a defibrillator. It provides real-time feedback on a patient’s heart rhythm, allowing medical personnel to assess the need for electrical cardioversion or defibrillation.

In the case of sudden cardiac arrest, immediate assessment of the heart's electrical activity is vital, and the LIFEPACK 15 enables responders to deliver shocks when appropriate. Additionally, it can display various vital signs, such as heart rate and blood pressure, helping to guide treatment decisions.

Other devices listed, such as the LUCAS 3, are vital for automated chest compressions but do not provide defibrillation capabilities. Ultrasound is primarily used for imaging rather than immediate intervention in cardiac arrest. Tranexamic Acid serves as a medication for reducing bleeding but is not related to monitoring or defibrillation in cardiac arrest scenarios. Therefore, the LIFEPACK 15 stands out as the appropriate choice for this context, effectively combining monitoring functions with the life-saving capability of defibrillation.
