The statement highlighting that ventilations are more effective when two rescuers operate the bag-valve-mask resuscitators (BVMs) is accurate due to the collaborative nature of the technique. When two rescuers are involved, one can effectively maintain an airtight seal on the mask while the other provides the necessary ventilations. This teamwork allows for increased efficiency and ensures that the delivered breaths are adequate, as one rescuer can focus on managing the device while the other monitors the patient's response and performs any necessary adjustments.

In scenarios where only one rescuer is available, it often becomes challenging to maintain proper ventilation and chest compressions simultaneously with a single BVM, which can lead to less effective airway management. Using two rescuers enhances the overall quality of care, increases the likelihood of adequate oxygen delivery to the victim, and helps in maintaining the victim's airway more effectively, making it the preferred approach in emergencies when resources allow for it.
