Paucis Verbis: Ventilator settings for acute lung injury and ARDS


A patient presents with severe multilobar pneumonia and refractory hypoxia requiring endotracheal intubation. The respiratory therapist connects your patient to the ventilator.

"What settings would you like your patient on?"

(In reality, the respiratory therapist already has placed your patient on the appropriate initial ventilator settings already, but let's think this through ourselves.)

Back in 2010, Dr. Scott Weingart of EMCrit fame, posted a great podcast on "Dominating the Vent". It's such a fantastic distillation of the practical aspect of ventilator setting management of all intubated patients except those with an acute asthma or COPD exacerbation, Dr. Jenny Wilson and I thought this would be a great Paucis Verbis card to have in your peripheral brain.

Note: The tidal volume should be calculated based on Predicted Body Weight (PBW), which is based on patient gender and height. The calculation is at the bottom of the card. Using a patient's actual weight might yield a tidal volume that is way too high. The initial vent settings in the example box are for a patient with a PBW of 70 kg. That's basically a 5'9" man or 5'11" woman.

Thanks to Dr. Jenny Wilson for the idea and writing this card, and Dr. Scott Weingart for a great podcast as always.
