METHOD AND APPARATUS FOR PREDICTION OF FLUID RESPONSIVENESS IN MECHANICALLY VENTILATED SUBJECTS

摘要

The present invention relates to a method for prediction of fluid responsiveness of a subject (3) connected to a breathing apparatus (1) capable of providing mechanical ventilation to said subject (3). The method comprises the steps of: -monitoring (S1) at least one parameter indicative of a degree of carbon dioxide elimination, VCO2, of the subject (3); -applying a PEEP maneuver in which a positive end-expiratory pressure (PEEP) applied to the subject is changed (S2) from a first PEEP level to a second PEEP level, and -predicting (S3) the fluid responsiveness of the subject (3) based on a change in said at least one monitored parameter following said change in PEEP.
