WebAirway resistance (Raw) is calculated as the ratio of sRaw to FRC(pleth). Raw is a measure of airway obstruction and indicates the alveolar pressure needed to establish a flow rate of 1 L s(-1). In contrast, sRaw can be interpreted as the work to be performed by volume displacement to establish this flow rate. WebRaw reflects changes in alveolar pressure over changes in airflow representing true resistance of the airways. In a study by Topalovic et al. on a sample of 976 subjects, 651 …
WebJan 1, 2012 · Spirometry is considered the primary method to detect the air flow limitation associated with obstructive lung disease. However, air flow limitation is the end-result of many factors that contribute to obstructive lung disease. One of these factors is increased airway resistance.
