Which statement describes the bag-mask device during CPR?

• A. It provides ventilation and acts as a barrier
• B. It helps defibrillate
• C. It monitors oxygen saturation
• D. It delivers medications

Answer: (A)

During CPR, the bag-mask device is used to provide ventilation by delivering breaths to the patient. Squeezing the bag pushes air into the lungs, often with supplemental oxygen, helping to maintain oxygenation while chest compressions continue. The mask and its seal act as a barrier, protecting you from exposure to the patient’s fluids and making ventilation more effective by reducing air leaks. This device does not defibrillate, monitor oxygen saturation, or deliver medications. Those roles are filled by the defibrillator, monitoring equipment, and medications, respectively.
