What You Should Be Able to Explain After Reading
- Explain the role of pulmonary rehabilitation in ILD.
- Assess dyspnea, functional capacity and exertional oxygen response.
- Individualize aerobic and resistance exercise.
- Recognize deterioration requiring medical review.
Clinical framework
- Interstitial lung diseases vary in cause and course but may cause restrictive physiology, impaired gas exchange, exertional dyspnea and reduced capacity. Resting observations can be reassuring despite exertional desaturation.
- The 2023 ATS guideline recommends pulmonary rehabilitation for adults with ILD. Exercise capacity and health-related quality of life may improve, although response and durability vary.
Baseline assessment
- Review diagnosis, stability, recent exacerbations, medication, oxygen prescription, comorbidities, falls, fatigue and goals. Clarify the prescribed oxygen plan during exertion.
- When medically cleared, assess with a 6-minute walk or sit-to-stand test, dyspnea and exertion ratings, heart rate, blood pressure and oxygen saturation. Follow local testing and emergency procedures.
- Track a relevant quality-of-life measure where available alongside walking capacity and a patient-specific activity goal.
Safety and differentials
- New or rapidly worsening breathlessness, fever, chest pain, syncope, hemoptysis, unilateral leg swelling or sudden unexplained oxygen deterioration requires prompt medical assessment.
- Do not apply one universal SpO2 stop threshold to everyone. Follow the individualized oxygen and escalation plan, local policy and symptoms; verify signal quality and allow recovery when appropriate.
Exercise prescription
- Use individualized walking or cycling, often interval-based when dyspnea limits continuous work, plus progressive resistance training for major muscle groups.
- For marked dyspnea, short work bouts such as 1–3 minutes with recovery may be a practical start. Resistance training can begin with light-to-moderate loads and controlled repetitions; exact dose depends on capacity, oxygen response and stability.
- Include pacing, breathlessness-management strategies and self-management education. Oxygen-flow changes belong within the prescribed medical plan, not ad hoc physiotherapy adjustment.
Progression and summary
- Increase total tolerable work before intensity when recovery is slow. Review dyspnea, exertion, oxygen response, recovery time and next-day response; change one variable at a time.
- Exercise limitation can reflect both deconditioning and gas-exchange impairment. Rehabilitation is beneficial, but monitoring and oxygen planning must be individualized; unexpected deterioration is not a cue simply to reduce exercise and continue.
