Study Notes
Respiratory System Overview
- The respiratory system consists of structures that enable breathing, gas exchange, and ventilation.
- The chest's anatomy includes major and accessory muscles for inspiration and expiration, such as the diaphragm and external intercostal muscles.
Pulmonary and Bronchial Function
- Pulmonary circulation is crucial for oxygenating blood, and bronchial circulation supplies airways' tissues.
- Mechanics of breathing involve lung elasticity and resistance in airways affecting airflow.
Clinical Manifestations of Pulmonary Disorders
- Dyspnea: Difficulty breathing can be transient or chronic, including symptoms such as exertional dyspnea, orthopnea, and paroxysmal nocturnal dyspnea.
- Cough and Sputum: Hemoptysis can indicate underlying issues.
- Hypoxemia vs. Hypoxia: Hypoxemia refers to low oxygen in blood; hypoxia denotes insufficient tissue oxygenation.
Upper Respiratory Disorders
- Common Cold: Mainly caused by rhinovirus, contagious before symptoms manifest and in early stages.
- Acute Rhinitis and Sinusitis: Inflammation of nasal and sinus mucous membranes.
- Symptoms: Nasal congestion, discharge, cough, and increased secretions.
Treatments for Upper Respiratory Disorders
- Antihistamines: Relieve allergic rhinitis symptoms and nausea; can cause drowsiness and dizziness.
- Decongestants: Stimulate alpha-adrenergic receptors, reducing nasal swelling and secretion.
- Expectorants, Antitussives: Help manage cough and mucus.
Lower Respiratory Disorders
- Restrictive vs. Obstructive Disorders: Restrictive disorders limit lung volumes, while obstructive disorders limit airflow (e.g., asthma, COPD).
- Pneumothorax: Presence of air in pleural space, affecting oxygenation and ventilation.
- Pleural Effusion: Accumulation of fluid in pleural space leading to loss of lung elasticity.
Pathophysiologic Changes
- Conditions like aspiration, atelectasis, and pulmonary fibrosis contribute to restrictive lung diseases.
- Acute respiratory distress syndrome involves inflammation and severe hypoxemia.
Acid-Base Balance
- Respiratory Acidosis: Caused by hypoventilation or muscle paralysis; treated with ventilation support.
- Respiratory Alkalosis: Results from hyperventilation; managed with rebreathing techniques (e.g., paper bag).
- Metabolic Acidosis/Alkalosis: Linked to systemic alterations; treatment tailored to underlying causes.
Analyzing ABGs
- pH levels indicate acidosis or alkalosis; corresponding PaCO2 and HCO3 levels determine respiratory or metabolic origins.
- A matching CO2 elevation with low pH indicates respiratory acidosis, while a high HCO3 suggests metabolic alkalosis.
Key Medications and Nursing Considerations
- Monitor vital signs and respiratory status during medication administration; be aware of potential side effects such as drowsiness or tachycardia.
- Use nasal decongestants short-term to avoid rebound congestion effects.
