• What should be weaned first, FiO2 or PEEP

  FiO2
• Pressure-volume curve


  Provides a visual of changes in pressure and volume as the lung is inflated, will show if patient is experiencing lung over-distention
• Lower Inflection Point (LIP)


  Point where compliance improves due to alveolar recruitment
• Upper Inflection Point (UIP)

  The beginning of over-distention due to too much volume or pressure being delivered
• Pressure-volume curve showing "bird beak"

  Indicates over-distention
• Pressure-volume curve


  Part relating to inhalation and part relating to exhalation
• Inhalation goes up and exhalation comes down
