Setting PEEP by BMI/3 might be a good starting point in patients with an elevated BMI
Understanding it may lead to over or under PEEP for about 2/3 of patients based on our OR population with variable BMIs

The mean of esophageal pressure estimates of optimal PEEP surprisingly approximated the mean of BMI/3 in our >100 patients with BMI <25 to >45
BUT
BMI/3 would only capture about 1/3 of patients esophageal pressure base transpulmonary pressure optimal PEEP (tPP of 0 +\-2)

Answer: #2 normotensive cardiogenic shock
It’s sneaky, easy to miss but important to identify, diagnose cause, manage and admit to ICU—not the floor tele unit
Occurs in about 12% of CS patients
Mortality 17%

“the PaO2/FiO2 ratio was significantly lower in the group treated with lower tidal volumes on days 1 and 3” (ARDSnet)
But as we know 28 day mortality was eventually higher in the larger tidal volume group
I wonder what we’re doing now in medicine that is similar?
