    Study Notes

    Common Causative Agents of Pneumonia

    • Pneumocystis Jiroveci: A common cause of pneumonia in patients with AIDS.

    • Pneumococcal pneumonia: The most common type of bacterial pneumonia.

    Pneumonia Symptoms & Diagnosis

    • Most common symptoms: Fever and productive cough.
    • Chest X-ray: The most convenient diagnostic tool for pneumonia.

    Pneumonia Differential Diagnosis

    • BNP (Brain Natriuretic Peptide): Used to rule out congestive heart failure.
      • Values greater than 100 pg/mL suggest heart failure.

    Staphylococcus Aureus

    • MRSA (Methicillin-Resistant Staphylococcus Aureus): A highly potent microorganism that can cause sepsis.

    Streptococcus pneumoniae

    • Gram-positive bacterium: A significant cause of pneumonia.

    Bronchodilators

    • Common examples: Albuterol, levalbuterol, salbutamol.
    • Common side effect: Tachycardia and palpitations.

    Corticosteroids

    • Characteristic: Medications ending with "-rone".

    Antibiotics

    • Suffix: "-mycin"
    • Anti-leukotriene: Montelukast (Singulair)
      • Mechanism of Action: Prevents bronchoconstriction.

    Pulmonary Rehabilitation

    • Huff laughing: A technique that combines pursed-lip breathing and mucus evacuation.

    Comfort Management

    • Low-dose morphine sulfate: Useful for pain relief.
    • Monitoring: Closely observe respiratory rate (RR) and oxygen saturation (O2 sat) for respiratory depression.

    Contraindications for COPD

    • Aminophylline: Provides more harm than therapeutic benefit.
    • Theophylline: Has a narrow therapeutic index and can lead to toxicity.

    Pneumonia: Inflammation of the Lung Tissue

    • Alveoli: Fill with fluid or pus.
    • Bronchioles: Also become inflamed.

    Risk Factors for Pneumonia

    • Elderly: Individuals over 65 years old.
    • Children: Those under 5 years old.
    • Immunocompromised patients: Individuals with HIV or cancer.
    • Patients with chronic diseases: Those with diabetes or COPD.
    • Smokers and alcoholics.
    • Severe malnutrition.
    • Postoperative patients.
    • Patients on mechanical ventilation.

    Differences Between Normal Bronchi and Chronic Bronchitis

    • Normal Bronchi: Have an open airway, smooth muscle, and normal mucus glands.
    • Chronic Bronchitis: Exhibit constricted muscle, narrowed airway, and excessive mucus production.

    Diagnosis of Chronic Bronchitis

    • Key Feature: Chronic productive cough (at least 3 months for 2 consecutive years).
    • Clinical Appearance: Often referred to as "Blue Bloaters" due to bluish skin discoloration and obesity.

    Interprofessional and Collaborative Management Strategies

    • Smoking cessation.
    • Trigger avoidance:
      • Atopic dermatitis.
    • Infection prevention:
      • Influenza and pneumococcal vaccines.
    • Nutritional support.
    • Increased fluid intake.
    • Pneumonia management.

    Pneumonia - Outpatient Management

    • Antinausea medications:
      • Azithromycin (Zithromax).
      • Keflex (cephalexin).

    Pneumonia - Hospital-Acquired Pneumonia (HAP)

    • Antibiotics:
      • Vancomycin.
      • Piptaz (piperacillin/tazobactam).

    Health Teachings for Pneumonia Patients

    • Importance of vaccines:
      • Pneumococcal and influenza vaccines.
    • Antibiotic adherence.
    • Follow-up chest x-ray after discharge (2 weeks).
    • Reporting fever or other concerning symptoms.

    Ventilator Alarms

    • High-pressure alarm: Indicates obstruction, such as:
      • Mucus secretions.
      • Kinking of the tubing.
      • Patient biting the tubing.
    • Low-pressure alarm: Indicates disconnection of the ventilator tubing.

    Pneumonia Management Goals

    • Length of stay: Aim for a 3-5 day hospital stay.
    • Ambulation: Encourage patients to ambulate.
    • Nutrition: Increase caloric and protein intake.
    • Incentive spirometry: To prevent lung collapse (not recommended for patients with COPD).
    • Huff laughing: To help clear secretions.

    Fever Evaluation

    • Culture and sensitivity: Perform before administering antibiotics.
    • Complete Blood Count (CBC): Evaluate for infection.
    • Imaging: Chest X-ray and CT scans to rule out pleural effusions and malignancy.

    Antibiotic Management

    • Community-Acquired Pneumonia (CAP): Azithromycin is commonly used.
    • Inpatient management: IV antibiotics like ceftriaxone, moxifloxacin, or levofloxacin.
    • Septic patients: Piperacillin-tazobactam is often combined with other antibiotics.

    Things to Avoid in Patients with Pneumonia

    • "Milking" chest tubes: Can increase intrathoracic pressure.
    • Clamping chest tubes: Can cause pneumothorax and increase pressure in the lungs.

    SIRS (Systemic Inflammatory Response Syndrome)

    • Clinical criteria:
      • Confusion (C): Sign of impending sepsis.
      • Azotemia (A): Buildup of urea in the blood.
      • Increased respirations (R): Alkaliosis.
      • Decreased BP ≥90 mmHg (B).
      • Temperature: Hyperthermia (early sign of sepsis) or hypothermia (late sign of sepsis).

    ARDS (Acute Respiratory Distress Syndrome)

    • Also known as pulmonary edema.
    • Non-cardiogenic in nature.
    • Fluid buildup: Due to inflammation (pneumonia) in the lungs.
    • Hallmark: Hypoxemia, which means inadequate oxygenation despite supplemental oxygen.

    Management of ARDS

    • Oxygen support: 8-10 L high flow.
    • Diuretics: Furosemide (lasix), but contraindicated in patients with BP < 90 mmHg.
    • Antibiotics: As needed to treat underlying infection.

    Thoracentesis

    • Procedure: Insertion of a needle into the intercostal space to remove fluid from the pleural cavity.
    • Monitoring: Vital signs, particularly BP for potential hypotension.
    • Significance: Analyzing the fluid helps with diagnosis (cytology, culture and sensitivity).
    • Symptom relief: Removing 71 mL fluid can relieve symptoms.
    • Chest tube connection: Thoracentesis fluid is often drained through a chest tube.

    Thoracic Drainage System Chambers

    • 1. Collection Chamber:
      • Measures the amount of fluid drained.
      • Allows air to flow into the water seal chamber.
      • Fluid color: Initially, bright reddish-brown blood (serosanguinous)
        • Gradually changes to pink, then serous (clear or yellow), then clear.
    • 2. Water Seal Chamber:
      • Measures air exiting the pleural space (fluctuation is normal).
      • Fluctuation indicates lung inflation.
      • Bubbling: Signifies an air leak.
    • 3. Suction Regulation Chamber:
      • Provides negative pressure to suction fluid from the pleural space.
      • Normal: Continuous, gentle bubbling.
      • Intermittent: Check gauge and pressure settings.
      • No bubbling: Inspect connections for leaks.

    Important Note Regarding Chest Tubes

    • Fluid drainage ≥ 100 mL / hour: Notify the provider as it may indicate hypotension.

    Additional Signs and Symptoms

    • Dyspnea on exertion.
    • Fatigue.
    • Increased respirations.
    • Body aches.

    Auscultation Findings

    • Crackles (rales):
      • Abnormal lung sounds.
    • Chest pain: Pleurisy (inflammation of the pleura) can cause sharp pleuritic pain during inspiration.
    • Altered mental status (LOC).
    • Signs of sepsis.

    3 Most Common Pneumonia Complications

    • 1. Pleural Effusion: Fluid accumulation in the pleural space (≥ 15-20 mL or more).

      • Types:

        • Hemothorax: Blood in the pleural space.
        • Pyothorax/Empyema: Pus in the pleural space.
        • Hydrothorax: Water in the pleural space.
        • Chylothorax: Lymphatic fluid in the pleural space (milky white, high lipid content).

      • Signs/Symptoms:

        • Chest pain (pleurisy/pleuritis).
        • Sharp pain with breathing.
        • Pleural friction rub (grating or creaking sounds).
        • Asymmetrical lung expansion (delayed on the affected side).
        • Decreased tactile fremitus (reduced vibration).

    • 2. Pneumonia:

      • Types:
        • Community-acquired pneumonia (CAP): Infection acquired outside of a hospital setting.
        • Hospital-acquired pneumonia (HAP): Infection acquired 48-72 hours after hospital admission.
        • Ventilator-associated pneumonia (VAP): Infection acquired from a mechanical ventilator.
        • Fungal pneumonia: Often seen in patients with impaired immune function.
        • Aspiration pneumonia: Typically occurs after aspiration of foreign material, often in patients with weakened protective reflexes.
        • Opportunistic pneumonia: Infection in patients with compromised immune systems.

    • 3. Lung abscess: Localized area of infection within the lung parenchyma.
