Which scenario best indicates the need for assisted ventilation with a bag-valve-mask (BVM)?

• A. The patient has inadequate breathing or is apneic.
• B. The patient is breathing adequately and tolerating effort.
• C. The patient is spontaneously breathing with normal rate.
• D. The patient requires long-term ventilation via tracheostomy.

Answer: (A)

Bag-valve-mask ventilation is indicated when a patient cannot provide adequate ventilation on their own—either they are not breathing at all (apneic) or their breaths are insufficient to maintain gas exchange. In that scenario, squeezing the bag delivers breaths that create positive pressure, helping oxygen move into the lungs and carbon dioxide be expelled while you secure the airway or prepare a more definitive airway. If a patient is breathing adequately and tolerating the effort, there’s no need for assisted ventilation with a BVM. Remember, BVM is for short-term support; long-term ventilation requires a ventilator via an airway such as an endotracheal tube or tracheostomy. Maintain a proper seal, monitor chest rise, and avoid overventilation, which can cause gastric distension and other problems.
