A 55-year-old man on ICU with ARDS is being ventilated. The team performs an end-expiratory occlusion test (EEOT) to assess fluid responsiveness. During the 15-second EEOT, cardiac output increases by 6%. What does this suggest?AThe patient is fluid overloadedBAn increase in cardiac output ≥5% during a 15-second EEOT suggests fluid responsiveness - the occlusion prevents the cyclical reduction in venous return caused by positive pressure ventilation, transiently increasing preload and thus cardiac output in fluid-responsive patientsCThe patient needs less PEEPDThe ventilator is malfunctioningEEEOT has no clinical valueCheck my answer
