High airway resistance on ventilator
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). WebAlthough high flow rates require a high pressure to overcome the high airway resistance of status asthmaticus, this pressure is dissipated across robust, cartilage-containing airways. Lower flow rates (eg, < 60 L/minute) reduce time available for exhalation, thereby increasing the end-expiratory volume (and the resultant intrinsic PEEP) and allowing a …

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. WebImproperly adjusted mechanical ventilation can exacerbate ARDS causing a secondary ventilator-induced lung injury (VILI). We hypothesized that a peak airway pressure of …
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, …
