Web5 de jan. de 2024 · In instances of higher airway resistance from some obstructive process, the flow scalar will show a decreased peak expiratory flow and a prolonged time for the expiratory curve to return to a baseline of zero flow (Fig. 2 b) [ 5 •]. All of this represents that the resistance to airflow is limiting how fast and how much volume the lung empties. 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, …
