16. Quality Check Partial effort dependent (determined by the leastic recoil of the lung) Steepness of the volume acceleration phase can be achieved from every patient independent of disease and degree of disease. Volume Flow- acceleration limitation End-expiratory phase Effort - dependent A: Maximal effort B: Submaximal effort C: Low effort A: Maximal effort B: Exhalation not complete A: Maximal effort B: Submaximal effort 1 2 3 Flow [L/s] Volume [L] TLC Effort dependent RV A B C A B A B
17. Quality Check Patient should exhale suddenly and forced. Patient should exhale suddenly and forced Patient should cough before starting the measurement Patient should inhale longer and to the maximum Patient should exhale as long as possible; minimal 6 s Different reasons; more details in next slight www.spiro-webCard.de
