Which device includes a one-way valve to aid in artificial ventilation and can be used with supplemental oxygen when fitted with an oxygen inlet?

• A. Nonrebreather mask
• B. Oxygen cylinder
• C. Partial rebreather mask
• D. Pocket face mask

Answer: (D)

A device designed for delivering rescue breaths while protecting you from exposure and allowing oxygen to be added during ventilation. The pocket face mask fits this role: it has a built-in one-way valve that directs your breaths to the patient and prevents exhaled air from returning to you, and it includes an oxygen inlet so you can supply supplemental oxygen during ventilation. This combination—a barrier with a one-way valve plus an oxygen input—is specifically what makes it ideal for assisted ventilation. The other options are mainly oxygen delivery tools rather than devices for manual ventilation: they provide high-concentration oxygen to a patient but aren’t designed to facilitate rescue breaths with a protective valve, or they require additional equipment (like a bag) to deliver breaths.
