Why do you need more oxygen when standing or moving?

When you're active—even just standing up or walking—your body needs more oxygen because your muscles are working harder. With emphysema, the damaged air sacs in your lungs can't absorb oxygen as efficiently, so your oxygen levels drop more during activity than they would when you're sitting still.

This is completely normal for people with COPD. Your body is demanding more oxygen during movement, but your lungs can't keep up with that demand as easily, which is why you need to increase your flow rate from 4 to 6 or 8 liters.

Many people with COPD need different oxygen levels for different activities:
- Lower flow rates when resting or sitting
- Higher flow rates during physical activity
- Sometimes adjusted rates during sleep

Your doctor can measure your oxygen levels at rest, during activity, and while sleeping to determine the right flow rates for each situation. This helps ensure you're getting enough oxygen without getting too much, which can also cause problems. What should you do?

Since you've been adjusting your oxygen on your own, it's important to talk with your doctor about your current needs. COPD is progressive, and after 3 years on oxygen, your requirements may have changed.

Your doctor can:
- Test your oxygen levels during different activities
- Prescribe the appropriate flow rates for rest and activity
- Make sure you're staying within a safe oxygen range
- Adjust your equipment if needed

Keep monitoring how you feel. Signs that your oxygen might be too low include shortness of breath, blue or gray-tinted lips or nails, fast heart rate, tiredness, or confusion.

A MyCOPDTeam member shared similar experiences: "Some good news the pulmonary rehab I'm going to seems to be working, Thursday they put my oxygen down to 2 liters from 3, and I was able to walk from the parking lot to rehab without getting out of breath."

Regular check-ins with your healthcare team will help you stay safe and comfortable as your needs change.
