    Study Notes

    Altered Respiratory Function

    • Conditions include COPD, Asthma, Emphysema, Tuberculosis, Pneumonia, Sinusitis, and Upper Respiratory Infections (URI).

    Anatomy and Physiology

    • Upper respiratory airway includes structures that filter, warm, and humidify air.
    • Lower respiratory airway encompasses bronchi, bronchioles, alveoli for gas exchange.
    • Proper functioning of the respiratory system relies on the anatomy and physiology for effective air movement and gas exchange.

    Etiology (Causes)

    • Respiratory disorders can stem from environmental factors, infections, allergic reactions, or lifestyle choices, such as smoking.

    Medication Overview

    • Antihistamines relieve symptoms like nasal secretions, itching, and sneezing; do not help with congestion. Examples: desloratadine, cetirizine, fexofenadine.
    • Decongestants promote vasoconstriction in nasal vessels; known side effects include increased blood pressure and heart rate. Caution advised for pre-existing conditions.
    • Nasal Steroids are effective in reducing inflammation and draining sinuses with minimal systemic side effects. Examples: Nasacort, Nasonex, Beconase, Flonase.

    Acute Viral Rhinitis (Common Cold)

    • Symptoms may include sneezing, sore throat, and nasal congestion; typically resolve without intervention.
    • Secondary infections may require antibiotics.

    Influenza

    • Characterized by sudden onset of fever, chills, body aches, fatigue, and respiratory symptoms.

    Sinusitis

    • Symptoms include facial pain, nasal congestion, headache, and a loss of smell.
    • Topical decongestants should not be used for more than 4-5 days to avoid rebound congestion.

    Pharyngitis

    • Bacterial pharyngitis often presents with fever, swollen lymph nodes, and tonsillar exudate, while viral pharyngitis typically shows redness and swelling without fever.
    • Treatment varies between antibiotic therapy for bacterial infections and symptom management for viral cases.

    Lower Respiratory Problems

    • Symptoms may include chronic cough, sputum production, and breathing difficulties.

    Tuberculosis

    • An infectious disease primarily affecting the lungs, characterized by a chronic cough, weight loss, fever, and night sweats.

    Obstructive Pulmonary Disease

    • Asthma is marked by variable airway obstruction and is often reversible; managed with bronchodilators.
    • Chronic Obstructive Pulmonary Disease (COPD) is mostly caused by cigarette smoking, leading to chronic bronchitis and emphysema.

    COPD Complications

    • Polycythemia Vera: Increase in red blood cells due to chronic hypoxia.
    • Cor Pulmonale: Right-sided heart failure resulting from pulmonary hypertension. Symptoms include distended neck veins and peripheral edema.

    Oxygen Therapy

    • Utilized for hypoxemia in respiratory disorders, O2 therapy improves survival in COPD patients.

    Oxygen Delivery Systems

    • Nasal Cannula: Most commonly used; safe and tolerable flow rates of 1-6 L/min.
    • Simple Face Mask: Suitable for short-term therapy; flow rates of 6-12 L/min, ensures snug fit.
    • Partial Non-Rebreather Mask: For higher oxygen concentrations (60%-90%); requires monitoring to prevent CO2 buildup.
    • High-Flow Nasal Cannula: Blends oxygen with compressed air to generate high FIO2 levels.

    Nursing Considerations

    • Monitor patients closely during oxygen therapy and be aware of potential advanced interventions required for respiratory distress.
