When using a bag-mask device, what should you observe to confirm effective ventilation?

• A. Chest rise
• B. Fogging of the mask
• C. Air leaks around the mask
• D. Color change in the face

Answer: (A)

The key indicator of effective ventilation with a bag-mask device is seeing the chest rise with each breath you deliver. That chest expansion shows air is actually entering the lungs and providing a tidal volume, which is what you want during resuscitation. Other signs like fogging of the mask or a color change in the face aren’t reliable measures of ventilation. Fog can occur for reasons unrelated to lung ventilation, and a mask leak means air isn’t reaching the lungs as well as it should, reducing effectiveness. So, focus on the visible chest rise as the best real-time cue, and if it’s not happening, adjust the seal, head position, or technique to improve ventilation.
