WebIn contrast to the spirogram, which displays airflow (in L) over time (in seconds), the flow-volume loop displays airflow (in L/second) as it relates to lung volume (in L) during maximal inspiration from complete exhalation (residual volume [RV]) and during maximum expiration from complete inhalation (TLC). 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 ...
