NR 601 Week 1 Pulmonary Function Test (PFT) Terms
NR 601 Week 1 Pulmonary Function Test (PFT) Terms/NR 601 Week 1 Pulmonary Function Test (PFT) Terms PFTs are: ERV IRV RV Vt FRC IC TLC VC FVC FEV1 FEV1/FVC Ratio Normal FEV1 N.ormal FVC Normal FEV1/FVC ratio Mild GOLD1 class (post bronchodilator FEV1) Moderate GOLD2 class (post bronchodilator FEV1) Severe GOLD3 class (post bronchodilator FEV1) Very severe GOLD4 class (post bronchodilator FEV1) How is reversibility determined? What are the steps to interpretation of PFTs? Interpret the following PFT: FVC 3.1L (73% predicted). Post-bronchodilator = 3.3L (77% predicted) FEV1 0.7L (23% predicted). Post-bronch = 0.8L (25% predicted) FEV1/FVC ratio (32% predicted) Interpret the following PFT: FVC 4L (88% predicted). Post-bronch = 4.1L (91% predicted) FEV1 2.6L (57% predicted). Post-bronch = 3.6L (89% predicted) FEV1/FVC ratio 65 (77% predicted). Post-bronch 77 (90% predicted) Interpret the following PFT: FVC 82%, post bronch 91% FEV1 52%, post bronch 55% FEV1/FVC 47%, post bronch 46% Interpret the following PFT: FVC 97%, post bronch 114% FEV1 82%, post bronch 107% FEV1/FVC 67% Interpret the following: FVC 104% FEV1 97% FEV1/FVC 79% Interpret the following PFT: FVC 100%, post bronch 103% FEV1 48%, post bronch 49% FEV1/FVC 37%, post bronch 39% Interpret the following PFT: FVC 91%, post bronch 97% FEV1 49%, post bronch 51% FEV1/FVC 47%
