Today's NEJM's cover article is by Gattinoni et al and they have looked at the ammount of "recruitable" lung in the setting of ARDS. This is after the results from the ALVEOLI study on High-Low PEEP.
How do you use PEEP in your ARDS patients? Have you been trying to "recruit" more lung with higher PEEP? Since the patients on the High PEEP did not have worse outcomes are you more comfortable with higher PEEP when oxygenation is a problem?
