Which of the following is true regarding bag-valve-mask ventilation?

Bag-valve-mask (BVM) ventilation is a critical skill in advanced airway management, and understanding the details associated with it is essential for effective patient care. When using a BVM, one key aspect to keep in mind is the pressure applied within the airway.

The correct option indicates that BVM ventilation may exceed 60 cm H2O pressure in the airway. This is significant because during manual ventilation with a bag-valve-mask, high pressures can be created if the bag is squeezed forcefully or if there is resistance in the airway, such as from an obstructed airway or increased lung compliance issues. Managing and recognizing these pressures is vital for avoiding complications, including barotrauma or gastric distension, especially if the ventilation technique is not optimized.

In practice, healthcare providers should be cautious when applying positive pressure ventilation since excessive pressure levels—especially above normal physiological limits—can adversely affect the patient. Thus, a good understanding of BVM technique and pressure limits is crucial for effective ventilation while minimizing injury. The ability to recognize when pressures are too high builds upon a rescuer's competency in airway management scenarios.

The comparison to the other choices reveals their limitations. For example, while it is true that removing dentures can affect the seal of the
