What is the correct volume of air to deliver during ventilations with a BVM?

The appropriate volume of air to deliver during ventilations with a bag-mask ventilation (BVM) is typically about 600 to 700 mL for an adult patient. This volume ensures adequate ventilation without causing over-inflation of the lungs, which can lead to complications such as barotrauma or decreased venous return due to increased intrathoracic pressure.

Choosing a volume higher than 700 mL may increase the risk of delivering too much air, potentially causing harm to the patient. Likewise, delivering less than 600 mL may not be sufficient to achieve effective ventilation. It's important to adjust the volume based on the patient's size and specific needs, but the standard recommendation stays close to this range for adults.

Therefore, 700 mL is widely accepted as a correct choice, ensuring effective ventilation while minimizing the risk of adverse effects, making it the correct answer in this context.
