Chronic respiratory failure happens when the lungs can no longer do their main job — getting enough oxygen into the blood and removing carbon dioxide from it. For people with COPD, this can develop gradually as the lungs become more damaged over time.
With COPD, the airways and air sacs in the lungs become damaged, making it harder to breathe efficiently. This can eventually lead to persistently low oxygen levels and/or high carbon dioxide levels in the blood.
Some signs that may point to worsening respiratory function include:
- Increasing shortness of breath, even at rest
- Persistent fatigue
- Confusion or difficulty concentrating
- Bluish tint to lips or fingertips (called cyanosis)
- Waking up with headaches
It's really important to speak with a doctor if breathing feels like it's getting worse over time. They can check oxygen and carbon dioxide levels through blood tests and adjust a treatment plan accordingly. Some people with advanced COPD may benefit from supplemental oxygen therapy to help manage this.
