Study Notes
Respiratory Conditions Overview
- Respiratory conditions addressed include basic chest infection, pneumonia, asthma, emphysema, bronchitis, pulmonary embolism, and respiratory distress.
- Types of chest infections: bronchitis (usually viral) and pneumonia (typically bacterial).
- Transmission occurs via cough/sneezes or contaminated surfaces.
High-Risk Groups for Chest Infections
- Infants and young children.
- Individuals with developmental issues or obesity.
- Elderly individuals and pregnant women.
- Smokers and those with chronic health conditions (e.g., asthma, heart disease, diabetes, kidney disease, cystic fibrosis, COPD).
- Individuals with weakened immune systems due to illness or treatments.
Symptoms of Basic Chest Infections
- Persistent cough with phlegm (yellow/green) or blood.
- Breathlessness, rapid/shallow breathing, wheezing.
- High fever, rapid heartbeat, chest pain, feelings of confusion.
Management of Basic Chest Infections
- Most are non-severe and self-limiting; recovery typically within days to weeks.
- Encourage rest, hydration, and self-treatment.
- Use analgesics (e.g., paracetamol, ibuprofen) for relief from headaches and body aches.
Pneumonia Pathophysiology
- Caused by inhaled bacteria/viruses leading to inflammation.
- Failure of lung defenses can lead to fluid and blood cell accumulation (consolidation).
Clinical Features of Pneumonia
- Signs: fever, productive cough, pain in chest/muscles/joints.
- Symptoms: increased respiratory rate, bronchial sounds on auscultation, and increased heart rate.
Management of Pneumonia
- Time-critical if presenting with major ABC problems or respiratory rate >30 bpm.
- Monitor and correct airway and breathing issues, and use oxygen therapy to maintain SpO2 of 94-98%.
- Non-time-critical management includes ECG, history assessment, and pain monitoring.
Pulmonary Embolism (PE) Pathophysiology
- Blood clots typically form in deep calf veins, travel to pulmonary arteries.
- Clots obstruct blood flow, leading to respiratory distress based on clot size and location.
Clinical Features of Pulmonary Embolism
- Symptoms include dyspnea, tachypnea, cough, and hemoptysis.
- Signs of severe cases: cyanosis, respiratory rates >20, heart rate >100, prolonged immobility risk factors.
Management of Pulmonary Embolism
- Time-critical with signs of severe hypoxia and respiratory distress.
- Immediate intervention needed for severe cases; monitor vital signs closely and administer oxygen.
Bronchitis Overview
- Inflammatory condition affecting airways; can be acute (viral/bacterial) or chronic (long-term lung damage).
- Common in elderly and those with smoking history.
Signs and Symptoms of Bronchitis
- Productive cough, dyspnea, cyanosis, tachycardia, reduced SpO2.
- Use of accessory muscles for breathing and potential cognitive impairments in severe cases.
Emphysema Overview
- Characterized by alveolar destruction and loss of lung elasticity.
- Patients often exhibit a barrel-shaped chest due to trapped air.
Signs and Symptoms of Emphysema
- Pursed-lip breathing, thin physique, perfused skin color, tachycardia/tachypnea.
- Anxiety or confusion, elevated blood pressure, and possible cardiac arrhythmias.
Asthma Overview
- A common yet potentially fatal condition, especially severe exacerbations.
- Presentations vary from moderate to life-threatening.
Pathophysiology of Asthma
- Airways hypersensitivity triggers bronchospasm and excess mucus production, leading to obstruction.
Common Asthma Triggers
- Environmental allergens: pollen, dust mites, cigarette smoke, pets, mold.
- Physical activity, stress, and temperature changes may also trigger episodes.
Severity Classification of Asthma Exacerbations
- Moderate: able to speak in sentences; SpO2 ≥ 92%.
- Severe: difficulty completing sentences; SpO2 < 92%, increased respiratory rate.
- Life-threatening: silent chest, cyanosis, or exhaustion.
Management of Severe and Life-Threatening Asthma
- Quick assessment and interventions required, including high-flow oxygen and nebulized medications.
- Necessary pre-alert call to the nearest emergency department; limit on-scene time for rapid transport.
Peak Expiratory Flow (PEF) Measurement
- Procedures for accurate PEF: ensure zero reading, perform in an upright position, take a deep breath, exhale forcefully into the device.
