Pulmonary Rehabilitation - Weaknesses Addressed

Weaknesses Addressed

  • Ventilatory limitation
    • Increased dead space ventilation
    • Impaired gas exchange
    • Increased ventilatory demands due to peripheral muscle dysfunction
  • Gas exchange limitation
    • Compromised functional inspiratory muscle strength
    • Compromised inspiratory muscle endurance
  • Cardiac dysfunction
    • Increase in right ventricular afterload due to increased peripheral vascular resistance.
  • Skeletal muscle dysfunction
    • Average reduction in quadriceps strength decreased by 20-30% in moderate to severe COPD
    • Reduction in the proportion of type I muscle fibres and an increase in the proportion of type II fibres compared to age matched normal subjects
    • Reduction in capillary to fibre ratio and peak oxygen consumption
    • Reduction in oxidative enzyme capacity and increased blood lactate levels at lower work rates compared to normal subjects
    • Prolonged periods of under nutrition which results in a reduction in strength and endurance
  • Respiratory muscle dysfunction

Famous quotes containing the words weaknesses and/or addressed:

    “Like most vigorous-minded men, seeing that there was no stopping-place between dogma and negation, he preferred to accept dogma. Of all weaknesses he most disliked timed and half-hearted faith. He would rather have jumped at once to Strong’s pure denial, than yield an inch to the argument that a mystery was to be paltered with because it could not be explained.”
    —Henry Brooks Adams (1838–1918)

    “Poor old Jonathan Bing
    Went home and addressed a short note to the King:
    If you please will excuse me
    I won’t come to tea;
    For home’s the best place for
    All people like me!”
    —Beatrice Curtis Brown (1901–1974)
