Key Respiratory Concepts and Considerations for the Quiz

The following sections outline key respiratory concepts that are frequently tested in medical-surgical nursing exams and are essential for providing safe and effective patient care.

Respiratory Assessment: The Foundation of Effective Care

A thorough respiratory assessment is the cornerstone of identifying and managing respiratory problems. It involves a combination of objective and subjective data collection.

• Subjective Data:
  • History: Gather information about the patient's past medical history, including respiratory conditions, allergies, medications, and smoking history.
  • Symptoms: Inquire about current symptoms such as shortness of breath, cough, chest pain, wheezing, and sputum production. Characterize the onset, duration, severity, and aggravating/alleviating factors of each symptom.
• Objective Data:
  • Inspection: Observe the patient's breathing pattern, chest wall movement, and use of accessory muscles. Note any signs of respiratory distress such as nasal flaring, retractions, or cyanosis.
  • Palpation: Assess chest expansion and tactile fremitus (vibrations felt on the chest wall during speech).
  • Percussion: Evaluate lung sounds by tapping on the chest wall. Resonance is normal, while dullness may indicate consolidation or fluid accumulation.
  • Auscultation: Listen to breath sounds using a stethoscope. Identify normal breath sounds (vesicular, bronchovesicular, bronchial) and adventitious breath sounds (crackles, wheezes, rhonchi, pleural friction rub).

Common Adventitious Breath Sounds:

• Crackles (Rales): Fine, short, crackling sounds heard during inspiration. May indicate fluid in the alveoli (e.g., pneumonia, heart failure).
• Wheezes: High-pitched, whistling sounds heard during expiration. May indicate airway narrowing (e.g., asthma, COPD).
• Rhonchi: Low-pitched, rattling sounds heard during inspiration or expiration. May indicate secretions in the large airways (e.g., bronchitis).
• Pleural Friction Rub: A grating or rubbing sound heard during inspiration and expiration. May indicate inflammation of the pleura (e.g., pleurisy).

Oxygen Therapy: Delivering Supplemental Oxygen

Oxygen therapy is a common intervention for patients with hypoxemia (low blood oxygen levels). The goal of oxygen therapy is to increase the partial pressure of oxygen in the arterial blood (PaO2) and improve tissue oxygenation.

• Delivery Methods:

  • Nasal Cannula: Delivers low concentrations of oxygen (24-44%) at flow rates of 1-6 liters per minute (LPM).
  • Simple Face Mask: Delivers moderate concentrations of oxygen (40-60%) at flow rates of 6-10 LPM.
  • Non-Rebreather Mask: Delivers high concentrations of oxygen (80-95%) at flow rates of 10-15 LPM.
  • Venturi Mask: Delivers precise concentrations of oxygen (24-50%) at specific flow rates.

• Key Considerations:

  • Oxygen Toxicity: Prolonged exposure to high concentrations of oxygen can damage the lungs.
  • Absorption Atelectasis: High concentrations of oxygen can wash out nitrogen from the alveoli, leading to alveolar collapse.
  • Humidification: Oxygen can dry out the mucous membranes. Humidification is recommended for patients receiving oxygen at flow rates greater than 4 LPM.

Airway Management: Maintaining a Patent Airway

Maintaining a patent airway is essential for ensuring adequate ventilation and oxygenation.

• Suctioning: Removing secretions from the airway using a suction catheter.
  • Nasopharyngeal Suctioning: Suctioning the nasopharynx and oropharynx.
  • Endotracheal Suctioning: Suctioning the endotracheal tube in mechanically ventilated patients.
• Artificial Airways: Devices inserted into the airway to maintain patency.
  • Oropharyngeal Airway (OPA): Used in unconscious patients to prevent the tongue from obstructing the airway.
  • Nasopharyngeal Airway (NPA): Used in conscious or semi-conscious patients to maintain an airway.
  • Endotracheal Tube (ETT): Inserted into the trachea to provide a secure airway for mechanical ventilation.
  • Tracheostomy Tube: Surgically created opening in the trachea for long-term airway management.

Medications: Managing Respiratory Conditions

A variety of medications are used to treat respiratory conditions. Understanding their actions, side effects, and nursing considerations is crucial for safe and effective medication administration.

• Bronchodilators: Relax the smooth muscles of the airways, opening them up and improving airflow.
  • Beta-Adrenergic Agonists: (e.g., albuterol, salmeterol) - Short-acting beta-agonists (SABAs) are used for acute relief of bronchospasm. Long-acting beta-agonists (LABAs) are used for long-term control of asthma and COPD.
  • Anticholinergics: (e.g., ipratropium, tiotropium) - Block the action of acetylcholine, leading to bronchodilation.
• Corticosteroids: Reduce inflammation in the airways.
  • Inhaled Corticosteroids: (e.g., fluticasone, budesonide) - Used for long-term control of asthma.
  • Systemic Corticosteroids: (e.g., prednisone, methylprednisolone) - Used for acute exacerbations of asthma and COPD.
• Mucolytics: Loosen and thin secretions, making them easier to cough up.
  • Acetylcysteine (Mucomyst): Used to break down mucus in patients with cystic fibrosis and other respiratory conditions.
  • Guaifenesin (Mucinex): An expectorant that helps to thin secretions.

Mechanical Ventilation: Supporting Respiratory Function

Mechanical ventilation is a life-saving intervention for patients with respiratory failure. It provides support for breathing until the patient can breathe on their own.

• Ventilation Modes:

  • Assist-Control (AC): The ventilator delivers a set volume or pressure with each breath, regardless of whether the breath is initiated by the patient or the ventilator.
  • Synchronized Intermittent Mandatory Ventilation (SIMV): The ventilator delivers a set volume or pressure at a set rate, but the patient can also breathe spontaneously between ventilator breaths.
  • Pressure Support Ventilation (PSV): The ventilator provides a set amount of pressure to assist the patient's spontaneous breaths.

• Key Considerations:

  • Ventilator-Associated Pneumonia (VAP): A common complication of mechanical ventilation. Implement VAP prevention bundles (e.g., head-of-bed elevation, oral care, suctioning).
  • Barotrauma: Lung injury caused by excessive pressure during mechanical ventilation.
  • Weaning: The process of gradually reducing ventilator support as the patient's respiratory function improves.

Chest Tubes: Managing Pleural Effusions and Pneumothoraces

Chest tubes are inserted into the pleural space to drain fluid or air and restore negative pressure, allowing the lung to re-expand.

• Indications:

  • Pneumothorax: Air in the pleural space.
  • Hemothorax: Blood in the pleural space.
  • Pleural Effusion: Fluid in the pleural space.
  • Empyema: Pus in the pleural space.

• Management:

  • Assessment: Monitor drainage, air leaks, and patient's respiratory status.
  • Dressing Changes: Maintain a sterile dressing around the insertion site.
  • Troubleshooting: Address any problems with the chest tube system (e.g., kinks, disconnections).

Arterial Blood Gas (ABG) Interpretation: Assessing Respiratory and Acid-Base Status

Arterial blood gases (ABGs) provide valuable information about the patient's respiratory and acid-base status.

• Key Values:

  • pH: 7.35-7.45
  • PaCO2: 35-45 mmHg
  • PaO2: 80-100 mmHg
  • HCO3: 22-26 mEq/L
  • SaO2: 95-100%

• Interpretation:

  • Acidosis: pH < 7.35
  • Alkalosis: pH > 7.45
  • Respiratory Acidosis: Increased PaCO2
  • Respiratory Alkalosis: Decreased PaCO2
  • Metabolic Acidosis: Decreased HCO3
  • Metabolic Alkalosis: Increased HCO3

Example:

ABG results: pH 7.30, PaCO2 50 mmHg, HCO3 24 mEq/L

Interpretation: Respiratory Acidosis (low pH, high PaCO2)
