High airway resistance on ventilator

WebTo avoid high plateau pressures during one-lung ventilation, it has been suggested to use V T of 5–6 ml/kg BW with PEEP in the absence of auto PEEP and to limit P plat to less than 25 cm H 2 O during one-lung ventilation. 21 However, application of PEEP in the dependent ventilated lung may increase pulmonary vascular resistance in this lung, … Web1.
