What is an immediate action if a patient exhibits inadequate ventilation during BVM?

When a patient exhibits inadequate ventilation during bag-valve-mask (BVM) ventilation, checking the mask seal and repositioning it if necessary is the most critical immediate action. Ensuring a proper seal is crucial for effective ventilation, as even a slight leak can prevent the delivery of adequate oxygen and ventilation to the patient.

Repositioning the mask typically involves adjusting it on the patient’s face to obtain a better fit or altering the angle of the patient’s head to optimize the airway. Using the appropriate technique, such as the "E-C" hold, helps maintain a tight seal, which is essential for effective positive pressure ventilation.

While increasing the oxygen flow rate, switching to an oropharyngeal airway, or administering oral suctioning might be relevant in certain clinical scenarios, they do not directly address the primary issue of inadequate ventilation occurring due to a poor mask fit. Therefore, ensuring an effective seal should always be the first priority during BVM ventilation.
