general philosophy Let’s admit it, nobody knows exactly how to set APRV. Numerous protocols and articles recommend different approaches. There has never been a human trial comparing two different APRV protocols, so it’s impossible to dogmatically say whether any protocol is better than any other protocol. The most successful clinical trial of APRV to date […]

IBCC chapter: Guide to APRV for COVID-19
COVID appears to cause a form of pseudoARDS (rather than true ARDS). This responds especially well to APRV, often avoiding many forms of iatrogenesis (e.g., proning, paralysis, myopathy, deep sedation, and delirium). Embracing APRV requires a zentensivist perspective on tidal volumes and minute ventilation (they will vary a bit! you won’t have total control of […]
PulmCrit- APRV: Resurrection of the open-lung strategy?
APRV is often used in surgical ICUs, but not medical ICUs. APRV may be viewed as a “new” technique by medical intensivists, whereas it’s been used for decades in surgical ICUs with great results. A fresh RCT may help resolve this.

CC Nerd-The Case of the Inverted Premise
No mode of ventilation is burdened with more emotional baggage than airway pressure release ventilation (APRV). The mere suggestion of its use is met with either the delight of recognizing an old friend whom you are meeting for the first time, or the type of disgust typically reserved for the likes of snake oil salesmen. […]
PulmCrit: ARDS vs. pseudoARDS – Failure of the Berlin definition.
Did this woman have ARDS? According to the Berlin Definition shown below, she had moderately severe ARDS while on conventional low tidal-volume ventilation (P/F ratio of 166). However, she didn’t meet the definition of ARDS while she was APRV, a few hours earlier (P/F ratio 475). Her overall clinical course with prompt recovery and weaning off oxygen is inconsistent with the natural history of ARDS.
PulmCrit – Defining ARDS & recruitability, with implications for COVID treatment
In the past few weeks, there has been considerable debate regarding whether or not early COVID respiratory failure is ARDS. This is a linguistic mess, but it has real implications for treatment. So, it’s worth trying to sort it out… definition(s) of ARDS When clinicians use the term “ARDS” they are referring to a variety […]
