    Study Notes

    Respiratory System Anatomy and Function

    • Intercostal muscles, diaphragm, accessory muscles, and abdominal muscles are crucial for respiratory mechanics.
    • The chest cavity protects the lungs while allowing room for lung expansion.
    • Pleura surrounds the lungs, containing fluid or air to facilitate expansion without damage.
    • Primary function of the pulmonary system is gas exchange to aid fluid and electrolyte balance.

    Pulmonary System Functions

    • Ventilation: Controlled neurochemically; involves respiratory center and chemoreceptors, along with lung elasticity and airway resistance.
    • Diffusion: Involves the transport of oxygen and carbon dioxide.
    • Perfusion: Refers to the blood flow in pulmonary and bronchial circulation; arteries carry blood away from the heart, veins carry it towards the heart.

    Indicators of Pulmonary Dysfunction

    • Common manifestations include dyspnea (difficulty breathing), altered breathing patterns (hypopnea or hyperpnea), coughing, sputum (including hemoptysis), cyanosis, nail clubbing, chest pain, and hypercapnia.

    Types of Dyspnea

    • Dyspnea may arise from respiratory infections, presenting with fever, cough, and swollen lymph nodes.
    • Treatments may include medications and proper respiratory techniques.

    Respiratory Infections

    • Caused by bacteria, viruses, or fungi infecting the lower respiratory tract.
    • Symptoms include runny nose, itchy eyes, and inflammation, with treatments like decongestants and antibiotics.

    Medications for Respiratory Conditions

    • Antitussives: Reduce cough reflex; contraindicated in non-chronic coughs and hypersensitivity.
    • Expectorants: Help in thinning mucus; contraindicated in individuals with diabetes or alcohol issues.
    • Mucolytics: Assist in liquefying mucus; contraindications include respiratory insufficiency.
    • Decongestants: Alleviate congestion; may cause side effects like nervousness and high blood pressure.
    • Antihistamines: Treat allergies; caution in those with urinary retention or liver diseases.
    • Nasal glucocorticoids: Reduce inflammation; monitored for side effects like nosebleeds.

    Nutritional Considerations for Respiratory Health

    • High protein and fiber diet can fortify respiratory muscles.
    • Echinacea, elderberry, garlic, oregano oil, and vitamins D and C are effective in boosting the immune system.

    Restrictive vs. Obstructive Pulmonary Disorders

    • Restrictive: Limits lung volume (e.g., pulmonary fibrosis).
    • Obstructive: Impairs airflow, difficult to exhale/inflate (e.g., asthma, COPD).

    Lower Respiratory Disorders

    • Pneumothorax: Air in pleural space; treated with needle aspirations and possible surgery.
    • Pleural Effusion: Fluid in pleural cavity; requires drainage via chest tube.
    • Atelectasis: Lung collapse; managed through inhalers and physical activity.
    • Pulmonary Fibrosis: Scarring of lung tissue; treatment may involve oxygen therapy.
    • Asthma: Chronic airway inflammation; managed with inhalers and nebulizers.
    • COPD: Chronic bronchitis and emphysema due to smoking; treated with oxygen therapy.

    Fractures and Joint Injuries

    • Fractures need to be classified by type (complete or incomplete, open or closed) and treated based on complications.
    • RICE (Rest, Ice, Compression, Elevation) is foundational for joint injuries.

    Inflammation

    • Cardinal signs include redness, warmth, pain, and loss of function due to increased blood flow and cellular response.
    • Systemic effects of inflammation can lead to complications like cardiovascular issues or infections.

    Bone and Joint Disorders

    • Osteoporosis leads to weak bones; treatment focuses on diet, exercise, and medication.
    • Rickets and Osteomalacia stem from vitamin D deficiency; managed through supplementation.
    • Joint conditions like arthritis and tendinitis highlight the importance of inflammation control.

    Medications for Bone and Joint Health

    • Bisphosphonates: Inhibit bone resorption, used in Paget's disease; care needed for GI issues.
    • Calcitonin-salmon: Lowers osteoclast activity for osteoporosis treatment.

    Proper Nutrition for Respiratory Disorders

    • Low carbohydrate, high protein, and fat diets may be recommended for chronic respiratory conditions to manage CO2 levels.
    • Small, frequent meals are suggested to avoid digestion impacts on breathing.
