In solo BLS, which method is used for ventilation after compressions?

• A. Mouth to Snout
• B. Mouth to Mouth
• C. Bag-Valve-Mask Ventilation
• D. No Ventilation

Answer: (A)

In solo BLS, after you start chest compressions you provide ventilation with rescue breaths delivered by mouth-to-mouth (or via a barrier device if one is available). This allows air to reach the lungs and oxygenate the blood while you continue compressions. Mouth-to-mouth is quickest and requires no equipment, which is why it’s the standard method when you’re alone and have no barrier device. If a bag-valve-mask or other barrier device is available and you’re trained to use it, that can be used for ventilation instead, but the basic concept remains delivering breaths after compressions. Note that in exam wording you might see “mouth-to-mouth” described in various ways; the idea is the same rescue-breath technique.
