Which device is Flow-Restricted Oxygen-Powered Ventilation Device?

• A. Venturi Device
• B. Nasal Cannula
• C. FROPVD
• D. Simple Facemask

Answer: (C)

Flow-Restricted Oxygen-Powered Ventilation Device is designed to actively deliver breaths using pressurized oxygen, with a built‑in flow-limiting mechanism to cap peak airway pressures. That safety feature helps prevent over-inflation while providing more consistent ventilation than manual methods alone. It stands apart from the other devices because it actually ventilates the patient with oxygen power, rather than just delivering oxygen passively.

A Venturi device uses oxygen to entrain room air to achieve a desired FiO2 but does not provide positive-pressure breaths. A nasal cannula delivers low-flow oxygen through the nostrils and does not provide ventilation. A simple facemask passes oxygen to the patient but does not actively push breaths into the lungs.
