Next workshop :: Poes practical session. We have Nutrivent. By Prof Alain Mercat , Oriol Rica , GIACOMO Grasselli. #LIVES2022 #ventilation #mechanicalventilation @ESICM
Values depends on the pt but if Poes is -15 then patient effort is very high. And for THOSE WITHOUT Poes, if you have a CVP and CVP values or waveform dips significantly during inspiration then you know that the patient effort is ++++ and intra thoracic pressure swing +++
It’s insane we have a live model (happily reading a book) whilst having a oesophageal catheter inserted ! And also a explanted lung model.
Definitely need training + empowerment of critical care nurses to gain confidence in inserting and using Poes. Like anything in intensive care , great bedside nurse is an absolute must.

Nutrivent. 4ml balloon + NG tube
Essentially theory : pleura pressure is positive. Which causes Alveoli to collapse - we put PEEP to counteract and prevent that collapse. By measuring Ppleural via Poes you could put the same PEEP to counter and thus prevent collapse of alveoli. P(lung) = P(airway) - P(oes).
Finally. Note end inspiration is not at the peak of P oes tracing.
