    Mechanical Ventilation: Practice, Indications for Mechanical Ventilation

  • Lesson Mechanical Ventilation: Practice addresses these key points

    • Respiratory Failure

    • Inadequate ventilation or oxygenation
    • Indication for mechanical ventilation
    • Can either be acute or chronic
    • Mechanical ventilation therapy may be required prior to obtaining blood gas analysis to confirm respiratory failure

    Breathing abnormalities that can result in decreased ventilation and/or oxygenation 

    • Ventilation without perfusion (dead space ventilation)
    • Diffusion abnormality
    • Perfusion without ventilation (shunting)
    • Hypoventilation

    In neonates:

    • Central nervous system not fully developed
    • Can contribute to irregular breathing and apnea 
      • Can in turn lead to acute episodes of inadequate ventilation

    Decreased Level of Consciousness

    • Traumatic injury of the central nervous system
    • Drowning or metabolic dysfunction

    End result:

    • Lack of control of respiration
    • Decreased ventilation and oxygenation
    • Requirement for mechanical ventilation

    CNS: Respiratory Muscle Fatigue

    • More common in pediatric patients
    • Occurs during muscle weakness, hypermetabolic states or chronic lung disease
    • Depleted ATP stores

    CNS: Inadequate Oxygenation

    • Respiratory disease
    • Pneumonia

    Cardiac Insufficiency

    • Work required for breathing decreased
    • Oxygen consumption by the heart reduced

    Chronic Respiratory Insufficiency

    • Failure to thrive can occur due to congenital conditions
    • Mechanical ventilation may occasionally be needed by these children

    Mechanical Ventilation

    • Respiratory distress 
    • Respiratory failure
