WebFeb 7, 2007 · Decelerating-ramp flow pattern on a flow-volume loop. Using Loops Loops allow the practitioner to analyze the inspiratory and expiratory phases of each breath using either flow-volume or pressure-volume tracings. On the flow-volume loop, volume is plotted on the x axis and flow on the y axis. WebA decelerating flow pattern is recommended for patients with acute respiratory distress syndrome (ARDS) and acute lung injury, because in addition to reducing the risk of VILI, the slow air flow rate and increase in mean airway pressure more evenly distribute …

WebMar 8, 2024 · We physiologically breathe with a decelerating flow pattern, where a large amount of gas rushes into our lungs very quickly then slows during the latter phase of inspiration. Pressure breaths mimic our normal flow pattern, where your set pressure is reached almost instantly causing a very large amount of gas to enter the lungs over a … WebJan 7, 2024 · With the flow waveform, the decelerating expiratory waveform does not reach the baseline before the inspiratory flow of the next breath begins.
