We developed a browser-based tool to predict ventilation impairments such as iPEEP buildup, hypoventilation, and desynchronization due to the tube resistance (also during bronchoscopy). Check it out: fabrylab.github.io/Bronchoscopy/

The flow limitation imposed by the endotracheal tube is a major cause of weaning failure, patient-ventilator desynchronization, and PSILI. During bronchoscopy, the tube resistance becomes prohibitive. Check out our paper medrxiv.org/cgi/content/sh…

How does a commercial ventilator (Dräger V600) in ATC mode compare to my 3-D printed ATC ventilator? Poorly, I would say, but judge for yourself. I am convinced that weaning can be greatly improved and shortened with real ATC. youtu.be/Y4To7-krE14

Today, I tested the Dräger Evita V600 ventilator in CPAP and ATC mode with a lung simulator. CPAP worked well, but in ATC mode, the V600 compensates only 25% of the total tube resistance, and that is possibly not enough to make a difference for patients.

I have moved to Bluesky (bsky.app/profile/atc-ve…) and hope my Twitter friends will join me there soon. While I may check in on Twitter occasionally, my primary activity will be on Bluesky. Looking forward to reconnecting there! @ArielG_RRT @DocMusician @Vent_Busters @_MSAMEED…

New on medRxiv! “How to minimize mechanical power during mechanical ventilation” For any given V'min, a tidal volume of twice the anatomic dead space (~4.4 ml/kg in adults) always minimizes elastic mechanical power (the energy needed for lung expansion). medrxiv.org/content/10.110…

The inflamed lung is full of immune cells, but how do they get there? We found that immune cells can generate large traction forces - comparable to fibroblasts - that help them migrate through narrow pores. Read more in Nature Physics: rdcu.be/dU9Nj

Interesting study. Patients with moderate to severe ARDS required less sedatives under a pressure-controlled mode with spontaneous breathing, compared to a volume-controlled mode without spontaneous breathing. Strangely, the PC patients could not be weaned earlier.
