WebBody plethysmography allows to assess functional residual capacity (FRC (pleth)) and specific airway resistance (sRaw) as primary measures. In combination with deep expirations and inspirations, total lung capacity (TLC) and residual volume (RV) can be determined. Airway resistance (Raw) is calculated as the ratio of sRaw to FRC (pleth). WebFeb 5, 2024 · It is for this reason that the ATS/ERS standards for plethysmographic lung volume measurements recommend a panting frequency between 30 pants/minute (0.5 Hz) and 60 pants/minute (1.0 hz). Note: This is also the reason that the subject’s hands are supposed to be placed firmly against their cheeks during the panting maneuver.
