It is estimated that more than 1.5 million Americans use supplemental oxygen, a vital therapy that helps people with conditions such as COPD and heart disease, get the oxygen they need to function and stay active. If you or someone you know is using supplemental oxygen, the CNS Home Medical Equipment team has tips for proper and safe usage.
Using Oxygen Properly
- Follow Your Prescription
Only use oxygen at the flow rate prescribed by your healthcare provider. Don’t adjust it on your own. - Use as Directed
Wear your oxygen during the day, at night, or during activity as prescribed — even if you feel fine. - Keep Equipment Clean
Clean nasal cannulas, masks, humidifier bottles, and tubing as directed (usually weekly). Replace cannulas every 2–4 weeks. - Check Your Supply
Regularly monitor your oxygen tank or concentrator levels to ensure you never run out. - Stay Hydrated
Oxygen can dry out your nasal passages. Drinking water and using a humidifier (if prescribed) can help.
Oxygen Safety: What to Avoid
No Smoking or Open Flames
Oxygen is not flammable, but it feeds fire. Stay at least 5–10 feet from open flames or anyone smoking.- Avoid Petroleum-Based Products
Don’t use Vaseline or oil-based creams on your face. Use water-based products only. - Keep Away from Heat Sources
Stay away from stoves, space heaters, candles, fireplaces, and electric razors near the face. - Store Tanks Safely
Keep oxygen cylinders upright and secured to avoid tipping. Store in well-ventilated areas.
Helpful Daily Tips
- Plan Ahead for Outings
Carry a portable oxygen supply and ensure you have enough for the trip. Bring backups if needed. - Watch for Symptoms
Call your healthcare provider if you feel more short of breath than usual, dizzy, or if your oxygen saturation is low. - Use a Pulse Oximeter
If advised by your provider, monitor your oxygen saturation (SpO₂). Keep track of patterns and report concerns. - Stay Active if Approved
Use oxygen during activity to stay mobile and improve quality of life (walking, light exercise).
Traveling with Oxygen
- Check with airlines, bus/train companies ahead of time.
- Bring medical documentation and extra supplies.
- Use FAA-approved portable oxygen concentrators if flying.
