Can PPOB be used for basic life support?

• A. No, because PPOB only supplies oxygen when a person is physically breathing
• B. Yes, PPOB can be used for basic life support.
• C. PPOB is used only on medical emergencies
• D. PPOB provides continuous oxygen regardless of breathing

Answer: (A)

Basic life support relies on keeping the airway open and providing breaths when the person isn’t breathing, with supplemental oxygen used to boost oxygen in the lungs as ventilation continues. A device that only delivers oxygen when the person is already breathing won’t help if breathing has stopped, because there are no breaths to trigger the flow. In resuscitation, you need to ventilate the patient (for example with rescue breaths or a bag-valve-mask) and/or ensure oxygen delivery during ventilation. That’s why this device isn’t suitable for basic life support—the oxygen flow won’t occur once breathing ceases, which defeats one of the essential BLS steps.
