During bag-valve-mask resuscitation, what is the most immediate indicator that air is reaching the target area?

• A. Identify the extent of pupil dilation
• B. Determine if the patient's chest is rising
• C. Examine the color of the patient's skin
• D. Determine if air is escaping from the patient's nostrils

Answer: (B)

During bag-valve-mask resuscitation, the quickest, most direct sign that air is reaching the lungs is visible chest rise with each breath. When you squeeze the bag, air should inflate the lungs, causing the chest to expand. That movement confirms that air is entering the airway and reaching the target area.

If the chest doesn’t rise, you know there’s a problem to address—likely a poor mask seal, an airway obstruction, or an improper head/neck position. Other signs, like pupil changes or skin color, reflect oxygenation or neurological status but are not reliable immediate indicators of ventilation effectiveness. Air escaping from the nostrils points to a leak around the mask rather than confirming that air is entering the lungs.
