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, … WebWhat causes high peak pressure on ventilator? Acute causes of elevated airway resistance are bronchospasm, anaphylaxis, endotracheal tube obstruction or ventilator circuit obstruction (e.g. the ventilator tubing is kinked). During an inspiratory pause, the ventilator waveform would show a tall spike (see below).
