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.
