What does effective use of a BVM require from both operators?

The effective use of a Bag-Valve-Mask (BVM) requires synchronization of movements between both operators. This is crucial because when one operator is delivering breaths by squeezing the bag, the other must ensure a proper seal with the mask on the patient's face. Without this coordination, the air delivered may escape, leading to inadequate ventilation and potential complications in resuscitation efforts. Effective communication and timing between the operators are essential for maximizing the efficacy of the BVM and ensuring that the patient receives the precise breaths needed to maintain their airway and facilitate oxygenation.

While knowledge of advanced life support and physical strength can be advantageous in some scenarios, they are not prerequisites for the effective operation of a BVM by two trained responders. Additionally, the use of automated devices is not typically involved in the manual operation of a BVM, as this device relies on the hands-on skills of the operators working in tandem.
