Open Access Abstract Introduction Reduction of automatic pressure support based on a target respiratory frequency or mandatory rate ventilation MRV is available in the Taema-Horus ventilator for the weaning process in the intensive care unit ICU setting. We hypothesised that MRV is as effective as manual weaning in post-operative ICU patients. Methods There were 106 patients selected in the postoperative period in a prospective randomised controlled protocol. When the patients arrived at the ICU after surgery they were randomly assigned to either traditional weaning consisting of the manual reduction of pressure support every 30 minutes keeping the respiratory rate tidal volume RR TV below 80 L until 5 to 7 cmH2O of pressure support ventilation PSV or automatic weaning referring to MRV set with a respiratory frequency target of 15 breaths per .
