Chronic Respiratory Failure: Diagnosis & Long-Term Management
A clear guide to chronic respiratory failure, covering diagnosis, oxygen therapy and long-term management options.
Treatment usually begins with
Pulmonologist Assessment
Blood Gas & Oxygen Testing
Long-Term Oxygen Therapy
Non-Invasive Ventilation
Management centres on oxygen therapy and, where needed, non-invasive ventilation to support breathing long-term.
You may need this evaluated if...
An evaluation for chronic respiratory failure is recommended when:
- Persistent low oxygen levels on testing
- Breathlessness that has progressively worsened
- An underlying lung condition with declining function
- Morning headaches or daytime sleepiness with a lung condition
Chronic respiratory failure can be managed effectively with the right long-term support plan, helping maintain quality of life.
What is Chronic Respiratory Failure?
Chronic respiratory failure occurs when the lungs can no longer maintain adequate oxygen or carbon dioxide levels in the blood, usually as a result of advanced underlying lung disease.
Usually a Later-Stage Finding
Often develops as an underlying lung condition progresses.
Two Main Types
Low oxygen and high carbon dioxide levels each need a slightly different approach.
Long-Term Support Helps
Oxygen therapy and ventilation support can significantly improve quality of life.
Managed, Not Always Reversed
The focus is on supporting breathing and treating the underlying cause.
Common Symptoms
- Persistent breathlessness
- Fatigue and reduced exercise tolerance
- Morning headaches
- Daytime sleepiness
- Bluish lips or fingertips in more severe cases
What Increases Your Risk
A combination of medical, environmental and lifestyle factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
Arterial Blood Gas Test
Measures oxygen and carbon dioxide levels directly.
Pulse Oximetry
Provides a quick, ongoing measure of blood oxygen.
Pulmonary Function Tests
Assess the underlying lung condition's severity.
Sleep Study
Checks for breathing problems during sleep in select cases.
Treatment Approaches
Medical Care
- Long-term oxygen therapy
- Non-invasive ventilation (BiPAP) for select patients
- Treatment of the underlying lung condition
- Pulmonary rehabilitation
Procedural Care
Surgery is not part of routine treatment for chronic respiratory failure and is directed instead at the specific underlying lung condition, where applicable.
Treatment decisions are based on symptoms, test results, lung function and overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly is important for the best outcome.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing symptoms.
- Progressively worsening breathlessness
- Low oxygen levels found on testing
Seek Urgent Care
Call for emergency care immediately if you notice any of the following.
- Severe breathlessness at rest
- Confusion or bluish lips and fingertips
