Maybe I missed it back when I was in school(20yrs ago)...But, is there any significance, when the "static" compliance is higher than the peak airway pressure. Compliance=15, where the peak airway pressure is 8-9, tidal volume 499, checked all connections and no leaks.
Thanks

those numbers are not possible. Assuming even that your PIP and Ppl are the same a VT of 499 with a Ppl of 9 cmH2O and even no PEEP would create a Cs of 55 ml/cmH2O. If you add PEEP then the Cs goes up even higher. How were you calculating the Cs?

The static compliance is a calculation whereby the pressure is divided into the volume----after subtracting Peep and tubing compliance (not always). (Or is it late and it's reversed? heh heh)

Or did you mean the static pressure?

With adult patients those numbers don't make sense.

If you use the vent automatic compliance check it could be that the patient is sucking wind deep (hence the low PIP) and then during the insp hold the patient is breathing against it---generating high pressure and a low compliance calculation. ?

This is probably an error of active breathing. Active breathers will always make plataeu pressures questionable
