Who is typically required to operate a BVM for effective use?

The effective use of a Bag-Valve-Mask (BVM) typically requires two people because it ensures proper technique and increases the likelihood of delivering effective ventilation. One person is needed to hold the mask securely on the person's face while the other person squeezes the bag to provide positive pressure ventilation. This two-person approach allows for better coordination, minimizes the risk of air leakage around the mask, and helps to ensure that the airway remains open during ventilation.

Having two rescuers also allows for one individual to focus on ensuring a proper seal and maintaining the correct positioning, while the other can concentrate on delivering the breaths, facilitating more effective support in emergency situations. In settings where additional resources and personnel are available, teamwork significantly improves outcomes for the patient needing assistance.
