Algorithm for intraoperative GDT as recommended by Deltex, manufacturer of the Oesophageal Doppler Monitor. The user monitors the response of the cardiac SV to an initial colloid bolus.14 Where fluid responsiveness is present, a further bolus is administered. Where it is absent, the user tracks changes in SV, using a drop of more than 10% as the cue for a fluid challenge.
