Which device should be used to deliver supplemental Oxygen after a scuba decompression?

• A. First Aid Kit
• B. Pocket Mask
• C. Portable Oxygen Bottle
• D. AED

Answer: (C)

Delivering supplemental oxygen quickly is crucial after a scuba decompression because high-concentration oxygen helps speed the off-gassing process and reduces the risk of hypoxia. A portable oxygen bottle provides a dedicated source of oxygen that can be connected to a regulator and delivered through a nasal cannula or mask, making it the most effective way to supply oxygen in the field. The other options don’t provide reliable oxygen delivery. A basic first aid kit isn’t a source of oxygen. A pocket mask is used for delivering breaths but does not supply high-concentration oxygen on its own. An AED is for cardiac emergencies and has no role in delivering oxygen.
