TESTE SPIROMETRICE
IMPORTANTA PRACTICA (1)
• a crescut frecventa bolilor pulmonare - bronsita cronica - astmul bronsic - fibrozele pulmonare
• Gradul disfunctiei pulmonare coreleaza cu perspectiva de viata

TESTE SPIROMETRICE
IMPORTANTA PRACTICA (2)
•Noile clase de substante bronhodilatatoare necesita evaluari obiective
• Extinderea chirurgiei toracice creste nevoia de expertizare a bolnavilor pulmonari

PARAMETRII SPIROMETRICI
FEV1 = Forced Expiratory Volume In 1sec = VEMS
PEF = Peak Expiratory Flow = Flux Expirator de Varf
VC = Vital Capacity = Capacitate Vitala
![Page 9: spirometrie](https://reader036.vdocumente.com/reader036/viewer/2022082412/5514a8d84979591b1e8b483a/html5/thumbnails/9.jpg)
PARAMETRII SPIROMETRICI
FVC = Forced Vital Capacity = Capacitate Vitala Fortata
FER = Forced Expiratory Rate = FEV1 / VC = Ind. TIFNEAU
F50 = Forced Expiratory Rate at 50%
F25 = Forced Expiratory Rate at 25% MEF = Mid Expiratory Flow
