Background
- Intubation and ventilation typically required for respiratory failure or airway protection/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
