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) comprises the steps of: - monitoring (Si) at least one parameter indicative of a degree of carbon dioxide elimination, VC02, 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. 用于预测与能够向其提供机械通气的呼吸设备(1)相连接的对象(3)的流体响应性的方法包括以下步骤：-监测(S1)指示对象(3)中二氧化碳清除程度VCO的至少个参数；-应用呼气末正压(positive end-expiratory pressure，PEEP)操作，其中施加于所述对象的PEEP从第PEEP水平改变(S2)为第二PEEP水平，以及-基于PEEP的所述改变之后的所述至少个所监测参数的变化来预测(S3)所述对象(3)的流体响应性。
