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. 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 … 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.
