    Study Notes

    Pulmonary Disease and Nutrition

    • Optimal nutrition is essential for the growth and development of the respiratory system, supporting structures, and related systems.
    • A well-functioning pulmonary system enables the body to obtain oxygen and remove metabolic byproducts, which is crucial for energy production and overall health.

    The Pulmonary System

    • The pulmonary system includes respiratory structures such as the nose, pharynx, larynx, trachea, bronchi, bronchioles, alveolar ducts, and alveoli.
    • Supporting structures include the skeleton and muscles.
    • The pulmonary system grows and matures during gestation and childhood, but no new alveoli are produced after approximately age 20.
    • With aging, there is a loss of lung capillaries, and the lungs lose elasticity.
    • The primary function of the pulmonary system is gas exchange, which enables the body to obtain oxygen and remove carbon dioxide.

    Anatomy of the Pulmonary System

    • The lungs have several functions beyond gas exchange, including:
      • Acid-base balance
      • Synthesis of arachidonic acid
      • Conversion of angiotensin I to angiotensin II
      • Secretion of surfactant
      • Immune defense

    Gas Exchange in the Pulmonary System

    • The lungs enable the body to obtain oxygen and remove carbon dioxide through the process of gas exchange.
    • The lungs also filter, warm, and humidify the air we breathe.

    Effect of Malnutrition on the Pulmonary System

    • Malnutrition has adverse effects on lung structure, elasticity, and function, as well as respiratory muscle mass, strength, and endurance.
    • Protein and iron deficiencies lead to low hemoglobin levels, compromising the oxygen-carrying capacity of the blood.
    • Deficiencies in calcium, magnesium, phosphorus, and potassium compromise respiratory muscle function.
    • Hypoproteinemia contributes to the development of pulmonary edema.

    Asthma

    • Asthma is characterized by bronchial hyperresponsiveness, airway inflammation, and airflow obstruction.
    • The syndrome results from complex interactions among genetic, immunologic, and environmental factors.
    • Asthma is characterized by increased mucus secretion, inflammation, and smooth muscle tightening, leading to smaller airways.
    • Asthma is a leading cause of hospitalization and death worldwide.

    Pathophysiology of Asthma

    • Genetic attributes, environmental exposures, and gene-environmental interactions contribute to the development of asthma.
    • Environmental factors linked to asthma development include indoor and outdoor allergies, air pollution, tobacco smoke exposure, and lower socioeconomic status.

    Diagnosis and Management of Asthma

    • Diagnosis involves identifying airflow obstruction, recurrence, and excluding other diagnoses.
    • Symptoms such as wheezing, coughing, shortness of breath, and chest tightness occur in most patients.
    • Management involves preventing airflow obstruction, controlling symptoms, and improving quality of life.

    COPD (Chronic Obstructive Pulmonary Disease)

    • COPD is characterized by airflow obstruction, which is not fully reversible.
    • Malnutrition is a common comorbidity in COPD patients, leading to poor prognosis and increased risk of infection.
    • Iron deficiency anemia is seen in 10-30% of COPD patients, and correcting anemia and iron deficiency improves dyspnea.
    • Patients with cor pulmonale may experience fluid retention, which can mask lean body mass wasting.

    Nutrition and COPD

    • COPD patients require adequate nutrition to meet their increased energy needs.
    • Depletion of protein, calcium, magnesium, potassium, and phosphorus contributes to respiratory muscle function impairment.
    • Goals of nutrition management include preventing weight loss, maintaining a desirable weight, and improving exercise tolerance.
    • Small, frequent meals, adequate calories, protein, vitamins, and minerals, and limitation of alcohol intake are recommended.
    • Supplements such as thiamin may be necessary, and adequate fluid intake is essential to help with sputum consistency and expectoration.
