What’s optimal PEEP for your patients with an increased BMI? Our study showed a simple equation you can use: PEEP = BMI/3 There’s variability, but BMI/3 approximates the mean optimal PEEP (by esophageal manometry) from BMI 25 to > 40 #EMIMCC #medsky www.sciencedirect.com/science/arti...

What’s the best site for chest compressions? Probably mid-LV Guideline recommended location overlies the LV in the minority of cases TTE may be a good tool to better localize mid LV and thus optimal compression location (esp if TEE unavailable) #foamcc www.sciencedirect.com/science/arti...

Can you allow a MAP of < 65 in your patients with septic shock? Yes! Maybe as low as MAP of 50 But you must examine to make sure they are perfused -capillary refill < 3 seconds, warm extremities without mottling -adequate urine output -clearing lactate #EMIMCC journals.lww.com/ccmjournal/a...

How do you stop hydrocortisone once septic shock has resolved? I tend to be an abrupt discontinuation kind of person, stop as soon as the pressors are off rather than taper (unless it’s been a prolonged course) Restrospective evidence 👇 journals.lww.com/ccejournal/f...

Which has a higher mortality? 1. Patient with EF 30% BP 80/56 with lactic acid 1.8, normal LFTs, and warm extremities OR 2. Patient with EF 30% BP 100/70 with lactic acid 3.8, elevated LFTs and cool distal extremities

What in critical care medicine do you think makes the patient look better in the short term but is actually worse in the longer term? 25 yrs ago we might have said look my patient with ARDS and 12 ml/kg tidal volume is oxygenating better, so it must be superior to 6 ml/kg

Intensivists and Respiratory Therapists: 🫁 What’s your go to tidal volume for the patient without ARDS and why? 6 ml/kg PBW 8 ml/kg PBW 10 ml/kg PBW Something else?

What’s the highest IPAP you’ll use with NIV in a patient with COPD and respiratory failure? Before this trial I’d stop at ~ 20 cmH20, and think about intubating if not improving After this trial: Now up to 30 cmH20 may safely avoid intubation jamanetwork.com/journals/jam...
