What is a significant complication that may arise when using a resuscitation mask?

Maintaining a proper seal and open airway is crucial when using a resuscitation mask because a poor seal can lead to ineffective ventilation and prevent the delivery of oxygen to the patient. When a mask does not fit snugly against the face, air can escape around the edges rather than entering the lungs, diminishing the effectiveness of the rescue breaths. Additionally, if the airway is not kept open, any efforts to ventilate may be futile, as the airflow is obstructed. This underscores the importance of ensuring a good seal and clear airway during resuscitation efforts to optimize outcomes for the patient.

While the other options are certainly relevant to mechanical challenges encountered in resuscitation, they do not directly address the immediate physical interaction and skill required in the proper use of the resuscitation mask, which is foundational for effective emergency response.
