Study Notes
Chest X-Ray
- A diagnostic tool to assess the lungs and chest
- Used to detect abnormalities in the airways, lungs, and surrounding structures
Components of Oxygenation
- The process of delivering oxygen to the tissues
- Essential for maintaining cellular function
Restrictive Conditions
- Lung diseases that decrease lung volume and expandability
Pulmonary Edema
- Fluid accumulation in the lung tissue
- Causes:
- Cardiogenic: Due to heart failure, leading to increased pressure in the pulmonary circulation
- Non-cardiogenic: Due to other factors like sepsis, trauma, or altitude sickness
- Symptoms: Dyspnea, anxiety, pink frothy sputum
- Treatment: Noninvasive ventilation (NIV), antihypertensives
Pleural Effusion
- Fluid accumulation in the space between the pleura layers
- Causes: Infections, cancer, heart failure
- Symptoms: Dyspnea, chest pain, cough
- Treatment: Thoracentesis (fluid removal), supplemental oxygen
Acute Respiratory Distress Syndrome (ARDS)
- Severe lung injury characterized by widespread inflammation and fluid leakage
- Causes: Sepsis, pancreatitis, trauma
- Symptoms: Hypoxia, dyspnea, high ventilator pressures, diffuse infiltrates on chest X-ray
- Treatment: Address the underlying cause, oxygen therapy, mechanical ventilation, prone positioning, extracorporeal membrane oxygenation (ECMO)
Neuromuscular Disease/Injury
- Conditions that affect the muscles involved in breathing
- Causes: Amyotrophic lateral sclerosis (ALS), polio, myasthenia gravis, Guillain Barre syndrome, spinal cord injuries
Pneumonia
- An inflammatory process affecting the lower airway
- Causes: Infections by viruses, bacteria, fungi, parasites
- Symptoms: Hypoxia, cough, dyspnea, fever, chest pain, infiltrate on chest X-ray
Pneumothorax
- Accumulation of air in the pleural space
- Causes: Trauma, spontaneous
- Types:
- Simple: Observation, oxygen therapy
- Severe: Decompression, chest tube placement
- Symptoms: Dyspnea, chest pain, feeling of impending doom
Pulmonary Fibrosis
- A progressive disease where scar tissue forms in the lungs, making it difficult to breathe
- Causes: Medications, occupational exposure, autoimmune diseases, radiation
- Symptoms: Shortness of breath, dry cough, fatigue
- Treatment: Supplemental oxygen, lung transplant
Obstructive Conditions
- Lung diseases that obstruct airflow
Asthma
- Chronic inflammatory disease affecting the airways
- Causes: Allergens, irritants
- Symptoms: Wheezing, dyspnea, cough, fatigue
- Treatment: Bronchodilators, inhaled corticosteroids
- Signs of failure in an asthma patient: Absent breath sounds, altered mental status, low oxygen levels
Chest X-Ray
- Used to evaluate the lungs and surrounding structures
Components of Oxygenation
- Ventilation: movement of air in and out of the lungs
- Perfusion: blood flow through the lungs
- Diffusion: movement of oxygen from the alveoli to the blood
Restrictive Conditions
-
Pulmonary Edema: Fluid buildup in the lungs, can be caused by heart failure or other factors
- Symptoms: Dyspnea, anxiety, pink frothy sputum
- Treatment: Non-invasive ventilation (NIV), antihypertensives
-
Pleural Effusion: Collection of fluid between the pleural layers
- Positioning: Maintain high Fowler’s position
- Treatment: Supplemental oxygen, thoracentesis (removal of fluid)
Acute Respiratory Distress Syndrome (ARDS)
- Serious lung condition that occurs after an injury or illness
- Causes: Sepsis, pancreatitis, hypovolemic shock, pulmonary contusion, burns
-
Assessment findings:
- Precipitating insult (e.g. sepsis)
- Hypoxia
- Dyspnea (if not intubated)
- High ventilator pressures (if mechanically ventilated)
- Pulmonary edema
- Ground-glass appearance on chest X-ray
-
P:F Ratio: A quick assessment tool to evaluate ARDS severity
- Note: Not accurate in patients with V/Q mismatch
-
Treatment:
- Treat underlying cause
- Optimize oxygenation through safe ventilation
- ARDSnet mechanical ventilation protocol
- Prone positioning
- Maintain alveolar recruitment
- Extracorporeal membrane oxygenation (ECMO)
Neuromuscular Disease/Injury
- Muscular dysfunction impacting diaphragm and chest wall function
- Causes: Amyotrophic Lateral Sclerosis (ALS), polio, myasthenia gravis, Guillain-Barré syndrome, spinal cord injuries
Pneumonia
- Inflammatory process affecting the lower airways
- Causes: Viral, fungal, bacterial, parasitic
- Symptoms: Hypoxemia, productive cough, dyspnea, fever, pleuritic chest pain, subjective abdominal fullness, infiltrates on chest X-ray
Pneumothorax
- Accumulation of air in the pleural space
- Causes: Traumatic, spontaneous
- Symptoms: Dyspnea, impending doom, chest pain
-
Untreated: Can lead to tension pneumothorax
- Signs: Tracheal deviation
-
Treatment:
- Simple: Observation, oxygen administration
- Severe: Decompression, chest tube placement
Pulmonary Fibrosis
- Progressive scarring of the lungs
- Treatment: Supplementary oxygen, lung transplant
- Causes: Medications, occupational exposure, autoimmune disease, radiation
Obstructive Conditions
-
Asthma: Chronic inflammation of the bronchial walls, leading to bronchospasm and mucus production
- Symptoms: Wheezes, dyspnea, shortness of breath, grunting, orthopnea, fatigue, hypercapnia
- Signs of asthma failure: Absent breath sounds, altered mental status, low PaO2
