Study Notes
Respiratory Conditions Overview
- Conditions include COPD (Chronic Obstructive Pulmonary Disease), Asthma, Emphysema, Tuberculosis, Pneumonia, Sinusitis, and Upper Respiratory Infections (URI).
Anatomy and Physiology
- Comprises upper and lower respiratory airways, each with specific structures and functions crucial for effective gas exchange.
Upper Respiratory Airway
- Includes nasal passages, pharynx, and larynx.
- Key for filtering, humidifying, and warming inhaled air.
Lower Respiratory Airway
- Comprises trachea, bronchi, and lungs.
- Essential for conduction of air to the alveoli, where gas exchange occurs.
Etiology (Causes)
- Various factors including environmental, genetic, infectious agents, and allergens leading to respiratory diseases.
Medications for Respiratory Conditions
- Antihistamines alleviate nasal secretions and itching but do not relieve congestion. Examples: Desloratadine (Clarinex), Cetirizine (Zyrtec), Fexofenadine (Allegra).
- Decongestants (e.g., Pseudoephedrine) promote vasoconstriction but can raise blood pressure and heart rate. Risk of rebound congestion with overuse.
- Nasal Steroids reduce inflammation and facilitate drainage. Common ones include Nasacort, Nasonex, Beconase, and Flonase. Important for regular use.
Acute Viral Rhinitis - Common Cold
- Symptoms include sneezing, coughing, body aches. Secondary infections may require antibiotics.
Influenza
- Symptoms include fever, muscle aches, and fatigue.
- Vaccination recommended yearly.
Sinusitis
- Involves inflammation of the sinus cavities; symptoms include congestion, headache, and facial pain.
- Topical decongestants should not be used longer than 4-5 days to avoid rebound congestion.
Pharyngitis
-
Bacterial vs. Viral Differentiation:
- Bacterial: Fever, swollen lymph nodes, tonsillar/pharyngeal exudate, absence of cough.
- Viral: Red/swollen pharynx, pink nasal mucosa, palpable lymph nodes.
Lower Respiratory Problems
- Encompass a range of conditions affecting the lungs and airways.
Tuberculosis
- Infectious disease caused by Mycobacterium tuberculosis affecting lungs primarily.
Asthma
- Characterized by chronic inflammation and airway obstruction due to bronchospasms; triggers include allergens and irritants. Symptoms include wheezing, breathlessness, and chest tightness.
COPD (Chronic Obstructive Pulmonary Disease)
- Primarily caused by cigarette smoking.
- Characterized by obstructed airflow, chronic bronchitis, and emphysema.
Chronic Bronchitis
- Involves chronic cough and excessive mucus production over time.
Emphysema
- Results in destruction of alveoli leading to reduced elastic recoil and airflow.
COPD Complications
- Polycythemia Vera: Increased hemoglobin due to chronic hypoxia.
- Cor Pulmonale: Right-sided heart failure due to pulmonary hypertension; symptoms include dyspnea and edema.
Oxygen Therapy
- Critical in managing COPD and hypoxemia.
- Various delivery systems include:
- Nasal Cannula: Low flow, comfortable for patients, can deliver 1-6 L/min.
- Simple Face Mask: Serves short-term needs, delivers 6-12 L/min, must fit snugly.
- Partial Non-Rebreather Mask: Used for higher oxygen concentrations (10-15 L/min).
- Monitoring is essential to prevent skin breakdown around devices.
Patient Education and Safety
- Emphasis on adherence to medications and understanding situations that may exacerbate respiratory issues. Awareness of signs indicating the need for medical intervention is crucial.
