You and your partner are caring for a critically injured patient. Your partner is controlling severe bleeding from the patient's lower extremities as you attempt ventilations with a bag-valve mask. After repositioning the mask several times, you are unable to effectively ventilate the patient. You should:

• A. Continue attempted ventilations and transport immediately.
• B. Suction the patient's airway for 30 seconds and reattempt ventilations.
• C. Hyperextend the patient's head and reattempt ventilations.
• D. Begin ventilations using the mouth-to-mask technique.

Answer: (D)

When a bag-valve mask isn’t delivering effective breaths after trying to rebalance the seal, switch to a technique that provides a better seal and reliable ventilation. Beginning ventilations with the mouth-to-mask method helps you achieve a tighter, more consistent seal between the rescuer and the patient, which is often the key to delivering adequate tidal volumes in trauma situations where the mask fit is imperfect or facial trauma limits seal. This approach avoids wasting breaths on a poor seal and keeps ventilation moving without waiting for another repositioning attempt.

Hyperextending the head is not appropriate in a trauma patient because it can worsen a potential spinal injury and doesn’t fix the seal issue. Suctioning for 30 seconds could be useful if there is a clear airway obstruction from secretions, but it doesn’t address the problem of an ineffective mask seal. Mouth-to-mouth ventilation is less preferred when a mask is available, due to infection risk and practicality, so switching to mouth-to-mask is the best next step to restore effective ventilation.
