Endotracheal Tube (ETT) Depth and Tidal Volume Calculator
Use in patients over 20 years old.
Please fill out required fields.
- ETT position should still be verified with a chest radiograph among patients who will remain intubated for an extended period of time.
- Tidal volume: 6-8 mL/kg ideal body weight (IBW) is generally a safe initial setting, but further ventilator adjustment may be required depending on the adequacy of ventilation and airway pressures.
Endotracheal intubation and mechanical ventilation.
Chest radiograph and measurement of CO2 level (e.g. end-tidal CO2 or blood gas analysis) to confirm ETT position and adequacy of ventilation.
