Weba flow-volume loop is incomplete because the volume does not return to 0. this can be caused by which of the following conditions a. air trapping b. flow starvation c. BP fistula d. overdistention of alveoli c. BP fistula square wave represents constant parameter ramp wave represents variable parameter most common ramp wave is WebNov 11, 2024 · expiratory portion of the flow volume loop is characterized by a rapid rise to the peak flow rate, followed by a near linear fall in flow as the patient exhales toward residual volume. The Inspiratory curve, in contrast, is a relative symmetrical, saddle shaped curve. The shape of the flow-volume loop can indicate the location of airflow ...
