Raw airway resistance
WebSpirometry 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.

WebThe measurement of airways resistance using a body plethysmograph was first described by DuBois et al in 1956. Airway resistance (RAW) is the amount of pressure required to generate a given flow rate and is reported in cm H2O/L/Sec.
