Emergency Oxygen: Frequently Asked Questions (FAQ)

Be prepared for emergencies with clear answers about the use, safety, and benefits of emergency medical oxygen.

1. Why is Emergency Medical Oxygen Important?

During life-threatening emergencies, the body may lack oxygen, risking organ failure and brain damage. Emergency oxygen helps stabilize vital functions and increases survival chances.

2. Who Should Receive Emergency Oxygen?

Anyone experiencing a life-threatening illness or injury should receive oxygen — no exceptions.

3. How Is It Administered?

Breathing patients: Use a non-rebreather mask or nasal cannula.
Non-breathing patients: Combine with rescue breathing using a BVM (bag-valve mask) or CPR mask.

4. When to Administer Oxygen?

Immediately after ensuring the airway is open. If CPR is in progress, continue until oxygen is available.

5. Is Oxygen Ever Harmful?

Short-term emergency use is safe. Long-term use (over 5 hours) without medical supervision may have side effects.

6. Does It Replace Rescue Breathing?

No. For non-breathing victims, oxygen must accompany rescue breaths.

7. Should Oxygen Be Given After CPR Revival?

Yes, to prevent relapse and stabilize the patient until EMS arrives.

8. What if the Patient Improves?

Continue oxygen until professionals arrive.

9. Can It Replace the Heimlich Maneuver?

No. First clear the airway, then apply oxygen.

10. Unsure If They’re Breathing?

Begin rescue breathing with oxygen right away.

11. Difficulty Breathing But No Arrest?

Yes, oxygen helps prevent further deterioration.

12. Patient Can't Tolerate a Mask?

Hold it near their face — this still helps.

13. Prescription Required?

No. The FDA exempts emergency oxygen from prescription when used by trained personnel.

14. Who Can Administer It?

Anyone trained per FDA and manufacturer guidelines.

15. Maintenance Requirements?

Hydrostatic testing every 5 years for refillable tanks. Follow all storage and refill regulations.

16. Is Oxygen Dangerous?

Not flammable, but it supports combustion. Handle with care.

17. How Much Oxygen Should Be Stored?

Enough for 2× your local EMS response time, typically 30–60 minutes.

18. What Are OSHA Regulations?

Comply with compressed gas safety standards.

19. Bloodborne Pathogen Compliance?

Clean or dispose of contaminated parts per OSHA standards.

20. Unsure Whether to Use It?

Use it. The risks of not using oxygen are far greater.
