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).

Web12 de set. de 2024 · The compliance of a system is defined as the change in volume that occurs per unit change in the pressure of the system. In layman terms, compliance is the ease with which an elastic structure stretches. … 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.
Web3 de ago. de 2024 · In patients with congenital diaphragmatic hernia, resistance levels of > 400 cmH2O·kg/L/s may indicate high airway resistance and suggest greater alveolar vibration attenuation. When respiratory-system resistance reaches over 400 cmH2O·kg/L/s, it may be an optimal time for switching from high frequency oscillatory ventilation to … 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, …
