The Rationale for PR (II)

Complex treatment interventions often requiredo Immunosuppressive medicationso CPAP/BIPAP- acclimatization, training,

coaching, reassuranceo Transplantationo Mechanical ventilation/end of life decisions

Limited time for patient education and training with self-management strategies in the routine clinical setting

Pulmonary Rehabilitation is Effective

Problems faced

Respiratory muscle weakness

Peripheral weakness

Anatomical changes

• Reduced tidal volumes• Reduced lung

compliance• Ineffective cough• General fatigue• Decreased mobility• Positioning limitations• Possible impaired

swallowing and increased risk of aspiration

Faced Problems

• Reduce work of breathingIncrease tidal volumes and maintain lung

compliance

• Improve secretion clearance and effectiveness of cough• Maximise independence• Optimise quality of life

Core Components of PR for the “Non-COPD” Patient

Core Components of PR for the “Non-COPD” Patient

CPET: -identify exercise factors contributing

to symptoms and limitation

-formulate the exercise prescription

-Identify pulmonary vascular or cardiac limitations and/or need for supplemental O2

-Incremental exercise to high intensity NOT recommended for known severe pulmonary HTN or degenerative neuromuscular disease

Asses candidacy for inpatient PR

DISEASE SPECIFIC CONSEDERATOIN IN EXERCISE TRAINING (I)

Interstitial lung disease;

Pacing and energy conservation techniques

Slow and deep breathing Adequete oxygenation

Neuromuscular and Chest wall disease Maintain conditioning, avoid fatigue Consultation with neurologist/physiatrist Low intensity aerobic/water-based exercise Shorter, more frequent exercise sessions Emphasis on optimizing functional status Acclimatization to non-invasive ventilation

Disease-specific Considerations in Exercise Training (II)

Obesity related respiratory diseases

Strength and endurans exercise training/ Upper and Lower extremity Consider low-impact water-based exerciseBariatric equipment may be needed

Cardiac and musculo skeletal intervention before enrollment

Disease-specific Considerations in Exercise Training

(III)

Aerobic and Strength Training No evidence-based guidelines for exercise

prescription or training Mode, intensity and duration individualized

to patient ability and need using resources available

Age- and interest- specific modes

oxygen saturation > 90% Maintain Meet metabolic needs, avoid

anaerobic metabolism and exercise-induced increased PA pressure

o Test O2 saturation using patients’ own portable system
