PLR and Et-CO2

Q: Passive Leg raising (PLR) _______________ the End Tidal CO2 (ET-CO2)? - select one

A) decreases

B) increases

Answer: B

PLR-induced increase in EtCO2 by about 5 %. PLR increases fluid-induced increase CI by about 15 %.

There is weak evidence that ET-Co2 may be better than arterial pressure for predicting volume responsiveness by the passive leg raising test!
