Study Notes
Ventilation-Perfusion Mismatch
- Dead space: well-ventilated but poorly perfused alveolar regions.
- Shunting: well-perfused but poorly ventilated regions.
Laboratory Examination
- Types include ABG analysis, sputum analysis, direct visualization (bronchoscopy), indirect visualization (CXR, CT, MRI), and pulmonary function tests.
ABG Analysis
- Evaluates gas exchange in lungs by measuring gas pressures and pH of arterial blood.
- Normal values:
- PaO2: 80-100 mmHg
- PaCO2: 35-45 mmHg
- pH: 7.35-7.45
- HCO3: 22-26 mEq/L
- O2 saturation: 98-100%
- Pre-test: obtain a proper site and ready equipment.
- Intra-test: collect 5 mL of arterial blood from brachial, femoral, or radial arteries.
- Post-test: apply pressure for 5 mins, label, and ice the specimen.
Sputum Analysis
- Tests sputum for respiratory disease diagnosis, organism identification, and abnormal cells.
- Pre-test: encourage increased fluid intake.
- Intra-test: rinse mouth, take deep breaths, and ensure early morning sample.
- Post-test: provide oral hygiene and label specimens correctly.
Pulse Oximetry
- Non-invasive method for continuous monitoring of hemoglobin oxygen saturation.
- Used sensors on earlobe, forehead, fingertip, or nose bridge.
Bronchoscopy
- Direct inspection of trachea and bronchi via a flexible or rigid bronchoscope.
- Used for locating lesions, removing foreign objects, and tissue specimen collection.
- Pre-test: patient consent and NPO for 6 hours.
- Intra-test: sedate the patient and ensure they are positioned correctly.
- Post-test: NPO until gag reflex returns and monitor for hoarseness and complications.
Thoracentesis
- Aspiration of pleural fluid for analysis and relieving lung compression.
- Pre-test: obtain consent.
- Intra-test: position the patient appropriately and instruct not to move.
- Post-test: position for lung expansion, perform CXR, and monitor respiratory status.
Pulmonary Function Tests
- Assesses lung volume, capacity, and ventilatory function.
- Distinguishes between obstructive and restrictive diseases.
- Pre-test: educate patients and limit smoking and food intake before tests.
Common Respiratory Problems
- Dyspnea: difficulty in breathing, linked to conditions like CHF and muscular dystrophies.
- Coughing: protective reflex indicating various pulmonary conditions, including infections and tumors.
- Cyanosis: a late sign of hypoxia, need to check for airway patency and provide oxygen therapy.
Hemoptysis
- Coughing up blood, often due to infections or lung cancer.
- Requires airway management and possibly administering fibrin stabilizers.
Epistaxis
- Nosebleeds due to ruptured vessels, common at the anterior septum.
- Causes include trauma, hypertension, and infections.
- Interventions include positioning and direct pressure application.
Upper Airway Infections
- Common conditions include pharyngitis and tonsillitis, characterized by sore throat and fever.
- Key pathogens include Group A β-hemolytic streptococcus.
- Management involves antibiotics and hydration.
Respiratory Failure
- A critical condition marked by inadequate gas exchange, defined clinically by specific ABG values.
- Common causes include CNS depression and thoracic abnormalities.
- Symptoms include restlessness, cyanosis, and altered mental status.
- Treatment may involve intubation and oxygen therapy.
COPD
- Characterized by persistent air passage obstruction; primary cause is cigarette smoking.
- Management includes rest, increased fluid intake, and low carbohydrate diet strategies.
Bronchiectasis
- Normal bronchi dilation due to infection or congenital defects.
- Symptoms encompass chronic cough and dyspnea.
- Management focuses on hydration and maintaining airway clearance.
Pneumothorax
- Accumulation of air/fluid in pleural space leading to lung collapse.
- Types include spontaneous, open, and tension pneumothorax, each requiring distinctive interventions and assessments.
