What does airway resistance tell us about lung function?

WebOct 5, 2024 · Airway resistance (Raw) is calculated as the change in alveolar pressure (~ Pmo) divided by flow, which is derived by multiplying the slope of the closed-shutter maneuver (bottom left) and the inverse slope of the open-shutter maneuver (bottom right), with the Pbox (volume) terms canceling out. Full size image. http://www.respiratoryupdate.com/members/Airway_Resistance_Raw.cfm 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. can a hot shower wake you up
