How I set PEEP in ARDS: Professor Laurent Brochard

The AVF Podcast: ICU Tips & Tricks invites colleagues to share anything and everything on how they deal with various clinical situations. Expect discussions on how experts personalise evidence-based medicine for the patient at the bedside.
In this episode, Professor Laurent Brochard shares his thoughts on the setting of positive end-expiratory pressure (PEEP) in patients with acute respiratory distress syndrome (ARDS). Professor Brochard is Keenan Chair in Critical Care and Respiratory Medicine at St. Michael’s Hospital and the University of Toronto, Head of the Interdepartmental Division of Critical Care Medicine at the University of Toronto, Deputy Editor of the American Journal Of Respiratory and Critical Care Medicine, former Editor-In-Chief of Intensive Care Medicine, Head of the PLUG Working Group on pleural pressure for the European Society of Intensive Care Medicine, former Head and Member of the REVA (European Research Network on Mechanical Ventilation), and Member of the Canadian Critical Care Trials Group.
Issues discussed in this interview:
- Why we set a PEEP for ARDS and problems if the PEEP is too low or too high
- Ranges of PEEP when we say higher versus lower levels of PEEP
- Issues with the PEEP:FIO2 tables
- Issues with older ways of using compliance to define optimal PEEP
- Individualising PEEP using the recruitment-to-inflation ratio
- Other methods of individualising PEEP, including oesophageal pressure measurements and computed tomography (CT) scans
- Titrating PEEP after initial settings
- What to do if plateau pressure exceeds 30 cmH2O on optimal PEEP

Very interesting 👌

Nice

[@petrpiza3110]

Could you write down a link about RM a setting peep?

[@petrpiza3110]

I see it ....:))

Very confusing!
