Answer :
Final answer:
While one rescuer positions the BMV mask over the victim's mouth and nose, the other rescuer should handle squeezing the bag to deliver breaths. Proper mask seal and coordinated efforts between the rescuers are crucial in providing effective ventilations.
Explanation:
If you are positioning the mask over the victim's mouth and nose using a Bag-Mask Valve (BMV) during ventilations, the other rescuer should perform the actual ventilation. This involves squeezing the bag to deliver breaths to the victim. It is important for one rescuer to ensure the mask is sealed properly against the face to prevent air from escaping, while the other rescuer should focus on delivering the proper volume of air with each breath. The second rescuer may also assist with chest compressions if necessary, but it's essential that one person maintains a good seal with the mask at all times.
In a situation where only one rescuer is present, the American Heart Association advises that if you are not trained in giving rescue breaths, you should perform compression-only CPR. However, for trained rescuers like in your scenario, ventilations are also given using a BMV.
