How much volume does a bag-valve-mask (BVM) typically hold?

800 mL
1200 mL
1600 mL
2000 mL

The correct answer is: 1600 mL

The typical volume of a bag-valve-mask (BVM) is around 1600 mL. This volume is designed to provide adequate ventilation when administering positive pressure ventilation in emergency situations. The BVM's capacity allows for sufficient tidal volume to deliver an effective breath to an adult patient, ensuring that it can adequately inflate the lungs for oxygenation and ventilation needs. Understanding this aspect is essential for EMS personnel, as proper bag sizing directly impacts the effectiveness of respiratory support during critical care.
