What is a common mistake when using a BVM?

When utilizing a Bag-Valve-Mask (BVM) device, securing the mask properly is crucial for effective ventilation. When the mask is not secured correctly, air can escape, preventing adequate delivery of oxygen to the patient’s lungs. This can compromise the effectiveness of the ventilation and lead to further complications, including inadequate oxygenation and increased risk of aspiration. Securing the mask involves ensuring a proper seal against the patient's face to minimize air leakage, particularly around the edges of the mask.

Proper technique during BVM use is essential, which includes the correct positioning and securing of the mask. Without this step, even a well-functioning BVM may not deliver the necessary breaths effectively, which can be detrimental in an emergency situation where every second counts.
