Background

Intubation and ventilation typically required for respiratory failure or airway proctection/severe altered mental status

Categories of Respiratory Failure

  • Type 1 - Hypoxemia
  • Type 2 - Hypercarbia
  • Type 3 - Perioperative
  • Type 4 - Shock

Patient Positioning[1]

  • HOB elevation > 30 degrees
  • Reverse trendelenberg at 30 degrees in obese hypoventilaters
  • Lateral decubitus for severe unilateral lung disease
    • Good lung to Ground generally
    • Good lung UP in these exceptions:
      • Massive hemoptysis - prevent blood into dependent, good lung
      • Large abscess - pus fills up dependent lung
      • Unilateral emphysema - prevent hyperinflation
