Fig. 2From: A new perspective during laryngo-tracheal surgery: the use of an ultra-thin endotracheal tube (Tritube®) and flow-controlled ventilation—a retrospective case series and a review of the literatureSetting flow-controlled ventilation (FCV). Using FCV requires the setting of four parameters: (1) inspiration flow, (2) I:E ratio, (3) peak pressure, and (4) end-expiratory pressure (EEP). At the set flow rate, gas is insufflated from set EEP until it reaches the set peak pressure. Then, the flow is reversed and gas is sucked out at the rate to reach the set I:E ratio until EEP is reached, aiming for a linear decrease in intratracheal pressure. Then, a next insufflation with the set inspiration flow is started. Applied tidal volume results from the set driving pressure and respiratory system complianceBack to article page
