How might we monitor for development of this? Time to pay attention to resistance, oft neglected in the age of COVID #ARDS...

More on time constants here: derangedphysiology.com/main/cicm-prim…
In these cases we often see the expiratory phase on the flow diagram *not* return to baseline before the next inspiration is initiated
Larger delta between Ppeak and Pplat suggests ⬆️R
⬆️R can be dx by:
- ⬆️ time constant
- Failure of flow to return to baseline
- Forceful exhale
- ⬆️Ppeak with large delta of Peak - Plat
👁 on this in #COVID19 patients, especially after a few days on the vent
Don’t forget typical causes of ⬆️R, including asthma/COPD
(1) execute evidence-based, minimally burdensome care for #COVID19 patients
(2) don't chase magic bullets
(3) practice Early Goal-directed Palliation

And don't forget the vent waveform part of the thread:
