Background

Categories of Respiratory Failure

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
