Do obese patients get too much tidal volume?

- Literature has supported the use of the use of tidal volume of 6-8cc/kg of a patient's ideal body weight (IBW) for intubated patients. Try MDCalc's IBW calculator here.
- A study from last year reviewed the tidal volume being prescribed to patients in order to evaluate what tidal volume patients were receiving.
- 1 in 5 patients received an incorrect tidal volume, up to 10cc/kg IBW in some cases! Patients who were overweight or obese had an increased odds of receiving elevated tidal volumes during mechanical ventilation.
- Bottom line: Remember to calculate and use a patient's IBW when setting the tidal volume on the ventilator.
