    Study Notes

    Anticoagulant Complications

    • Stop the anticoagulant immediately if bleeding occurs. Contact the healthcare provider or Rapid Response Team.
    • Heparin-induced thrombocytopenia can lead to decreased platelet count, impaired gas exchange, increased blood carbon dioxide levels, and decreased pH.

    Obstructive Sleep Apnea (OSA)

    • OSA is most commonly caused by upper airway obstruction by the soft palate or tongue.
    • Contributing factors include obesity, large uvula, short neck, smoking, enlarged tonsils or adenoids, and oropharyngeal edema.
    • OSA disrupts sleep, preventing deep sleep needed for physiological restoration.
    • Apneic periods can result in arterial blood oxygenation levels below 80%.
    • Common symptoms include excessive daytime sleepiness, inability to concentrate, morning headaches, irritability, and nocturia.
    • Long-term effects include increased risk for hypertension, stroke, cognitive deficits, weight gain, diabetes, and pulmonary/cardiovascular disease.

    Asthma

    • The most important pulmonary function tests (PFTs) for asthma are forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1), measured using a spirometer.
    • Asthma is diagnosed when these values increase by 12% or more after treatment with bronchodilators.
    • Status asthmaticus is an emergent condition where normal asthma treatment fails to resolve the attack.
    • Asthma therapy aims to control and prevent episodes, improve airflow and gas exchange, and relieve symptoms.
    • Control therapy drugs are used daily regardless of symptoms; Laba (corticosteroid).
    • Reliever drugs are used to stop an attack; SABA (corticosteroid).

    Chronic Obstructive Pulmonary Disease (COPD)

    • COPD encompasses lower airway disorders that interfere with airflow and gas exchange, including emphysema and chronic bronchitis.
    • Emphysema is an alveolar problem, while chronic bronchitis affects the airways.
    • Chronic bronchitis involves inflammation of the bronchi and bronchioles, leading to excess mucus production and thickened bronchial walls, impairing airflow.
    • Cigarette smoking is the primary risk factor for COPD, alongside asthma.
    • COPD compromises gas exchange and oxygenation of tissues, leading to hypoxemia and acidosis.
    • Bacterial infections exacerbate COPD symptoms, increasing inflammation, mucus production, and bronchospasm.
    • Patients with emphysema have limited diaphragmatic movement due to diaphragmatic flattening.

    Pulmonary Embolism (PE)

    • PE is a clot originating from a different site that travels and lodges in the lungs.
    • A DVT is a clot forming in the leg that can become an embolism upon breaking off.
    • Patients at risk for PE should be monitored for shortness of breath, chest pain, and hypotension.
    • Symptoms can include a feeling of impending doom due to hypoxemia.
    • Patient safety measures include oxygen therapy, high-Fowler positioning, telemonitoring, IV access, and frequent assessment of vital signs and lung sounds.

    Pleural Effusions, Pneumothorax, and Hemothorax

    • A mediastinal shift is a sign of pressure on the lungs, often caused by pleural effusions, pneumothorax, or hemothorax.
    • A tracheal shift indicates a shift of the trachea, usually caused by trauma to the neck or hemo/pneumothorax.
    • Both conditions are considered medical emergencies.
    • Auscultation can reveal pleural friction rub (scraping sound) in pleural effusions and gurgling sounds (like a washing machine) in pulmonary edema.
    • Diagnostic testing includes chest x-ray, CT, MRI, and ABG.

    Chest Drainage Systems

    • Purpose: Removal of air or fluid from the lungs
    • Types: Three-bottle system (most common), water seal, and dry suction water seal.
    • Components: Suction control chamber/dry suction chamber, water seal chamber, and collection chamber.
    • Bubbling: Gentle bubbling is normal, excessive bubbling indicates an air leak.
    • Tidaling: Rise and fall of fluid in the water seal chamber with each breath.
    • Complications: Bleeding, pneumothorax, re-accumulation of fluid, subcutaneous emphysema.
    • Nursing care: Monitoring vital signs, drainage, and system integrity.

    Influenza (Flu) and COVID-19

    • Flu is an airborne virus, prevalent during fall and winter.

    • It causes acute respiratory infection, which can last for weeks.

    • Prevention: Vaccination (inactivated, recombinant, live attenuated, injection, or nasal spray); hand hygiene.

    • Diagnosis: Rapid Influenza Diagnostic Test.

    • Treatment: Antivirals (Tamiflu), started within 2 days of symptom onset.

    • COVID-19:

      • Prevention: Vaccination, hand hygiene.
      • Diagnosis: Nasal swabs (home or clinic).
      • Treatment: Antiviral therapy, supportive care.
      • Isolation: Quarantine until fever-free for 24 hours; hospital isolation in negative pressure room.

    Pneumonia

    • Risk Factors: Elderly, immunocompromised, GERD patients.
    • Causes: Infectious (bacteria, viruses, fungi) and non-infectious (toxins, smoke, aspiration).
    • Pathophysiology: Inflammation of alveoli filled with fluid/pus, inhibiting gas exchange, leading to coughing, fever, and dyspnea.
    • Diagnosis: Labs (CBC, CMP, sputum culture), imaging (x-ray, thoracentesis).
    • Treatment: Oxygen therapy, bronchodilators, HOB elevation, antibiotics.

    Tuberculosis (TB)

    • Transmission: Airborne/droplet transmission.
    • Infection:
      • Latent: Non-infectious phase.
      • Active: Contagious, causing inflammation in the lungs and lymph nodes.
    • Risk Factors: Developing countries, close contact with infected individuals, immunocompromised
    • Diagnosis: TB skin test, chest X-ray.
    • Treatment: Anti-tuberculosis medications.

    Pneumohemothorax

    • Definition: A condition where air and blood accumulate in the space between the lung and the chest wall (pleural space).
    • Causes: Trauma, coronary artery bypass surgery
    • Symptoms:
      • Respiratory distress
      • Diminished lung sounds in one area
      • Air hunger (gulping for breath)
      • Tension pneumothorax can cause tracheal or mediastinal deviation which requires immediate medical attention.
    • Diagnosis:
      • Arterial blood gases (ABGs)
      • Complete blood count (CBC) with differential (to identify possible infection)
      • Coagulation studies (to assess clotting ability)
      • D-dimer (to check for inflammation)
      • Chest X-ray
    • Management:
      • Thoracentesis and/or chest tube placement are usually required.

    Chest Injury

    • Types:
      • Blunt trauma (e.g., car accident)
      • No open, external wounds.
    • Symptoms:
      • Pain from trauma
      • Respiratory distress
      • Paradoxical chest wall movement (chest wall moves inward during inhalation and outward during exhalation)
      • Flail chest (a section of the rib cage breaks and moves independently)
    • Management:
      • Flail chest requires mechanical ventilation with humidified air to support breathing.
    • Monitoring:
      • ABGs, vital capacity, and signs of worsening hypoxemia/hypercarbia.

    Open Pneumothorax ("Sucking Wound")

    • Definition: An open wound penetrating the chest wall allowing air to enter and exit the pleural space.
    • Causes: Penetrating trauma (e.g., gunshot, stab wound)
    • Characteristics:
      • Audible air rushing in and out of the wound with each breath.
      • The chest wound does not directly puncture the lung, but the loss of pressure prevents air from entering the lung.
    • Recognition:
      • Chest wound with or without bleeding/foaming
      • Audible hissing/sucking sound
      • Mediastinal shift (alternating with ventilation)
      • Respiratory distress
      • Hemoptysis (blood in sputum)
    • Management:
      • Immediately seal the wound with a one-way valve (three sides sealed) to allow air to escape on inhalation and seal on exhalation.
    • Monitoring:
      • Closely monitor for tension pneumothorax, blood pressure, heart rate, and pulse patterns.
