Module 12: Oxygenation - Key Concepts and Interventions

Module Overview

  • Oxygenation: Key concepts regarding movement of oxygen through body systems and assessment strategies.

Learning Outcomes

  • Understand perfusion and ventilation related to oxygenation.
  • Apply the nursing process to clients with ventilation/perfusion issues.
  • Clinical decision-making and nursing interventions based on assessment findings.
  • Understand tracheostomies, chest tubes, and related responsibilities.

Airway Anatomy

  • Upper Airway: Nose, Mouth, Pharynx, Epiglottis, Larynx, Trachea.
  • Lower Airway: Bronchi, Bronchioles, Alveolar Ducts, Alveoli.

Oxygenation and Ventilation

  • Oxygenation: Process of obtaining O2 from the atmosphere (PaO2, SaO2).
  • Ventilation: Involves inspiration and expiration, dyspnea, accessory muscle use.

Signs of Inadequate Oxygenation

  • Restlessness, Confusion, Lethargy, Dyspnea, Cyanosis, Tachycardia, Pallor.

Nursing Assessment

  • Focus areas: Health history, vital signs, respiratory patterns (Tachypnea, Dyspnea).

Hypoxia & Hypoxemia

  • Hypoxemia: Low arterial oxygen level affecting breathing or circulation.
  • Hypoxia: Decreased oxygen supply to tissues, can be life-threatening.

Diagnostic Tests for Oxygenation

  • Pulse Oximetry, Sputum Cultures, Lung Biopsy, Bronchoscopy.

Nursing Interventions

  • Administer oxygen therapy, use of incentive spirometer, deep breathing exercises.
  • Chest Physiotherapy for secretion removal (Postural drainage, percussion).

Tracheostomy Management

  • Tube types: Cuffed, uncuffed. Potential complications include infection and aspiration.

Respiratory Problems & Management

  • Pneumonia: Inflammation caused by various pathogens. Requires antibiotics, supportive care.
  • Pulmonary Tuberculosis: Insidious symptoms; needs isolation and rigorous drug regimen for treatment.

Safety Measures

  • Use aspiration precautions: Elevate HOB, dietary adjustments for swallowing issues.

Prevention Strategies

  • Vaccination: Pneumococcal for at-risk populations.
  • Monitor patients: Early detection of respiratory symptoms to prevent complications.

Drug Therapy Overview

  • Anticoagulants, antibiotics, and fibrinolytics for management of embolisms and infections.
