Which oxygen device is primarily used to ventilate patients during ambulation when a portable vent is not available or can be used in emergency?

• A. Bag-valve mask (ambu-bag)
• B. Nasal cannula
• C. Non-rebreather mask
• D. Venturi mask

Answer: (A)

Focusing on giving breaths rather than just supplying oxygen, the bag-valve mask is the device designed for manual ventilation on the move. It’s a handheld, self-inflating bag connected to a face mask that you squeeze to deliver a breath to the patient. This lets clinicians provide positive-pressure ventilation during ambulation or in emergencies when a portable ventilator isn’t available, and it can be used with supplemental oxygen to improve delivery. The other options deliver oxygen but don’t actively ventilate. A nasal cannula provides low-flow oxygen to support breathing, not breaths. Non-rebreather and Venturi masks also deliver high FiO2 but rely on the patient’s own inspiratory effort rather than providing programmable breaths.
