Trach Tube Sizing
- Trach tubes have numbers corresponding to inner diameter size.
- Knowing sizes helps communicate with respiratory therapists.
Cuff Inflation
- Inflating the cuff on a trach creates a seal for positive pressure ventilation.
- Overinflation can cause tracheal necrosis and a vicious cycle of increasing cuff pressure.
Cuff Inflation and Aspiration
- Inflated cuffs can prevent large aspiration events but can also increase aspiration risk.
- Cuff inflation interferes with swallowing.
