WebDescription of the PISA data files. The main data files are the student, the school and the cognitive datasets. These data files are available for each PISA cycle (PISA 2000 – PISA 2015). From 2006, parent and process data files, from 2012, financial literacy data files, and from 2015, a teacher data file are offered for PISA data users. WebWhat is the normal systolic gradient? 3 mm Hg (mean 19.3 +/- 4.0); 35.8% of patients had values higher than 20 mm Hg. In conclusion, a tricuspid gradient of 30 mm Hg may be considered as the upper normal limit. WebDec 7, 2024 · Volume Flow Rate VFR (mL/s) = 2 x π x r 2 x V r. Effective Regurgitant Orifice ERO (mm 2) = VFR / V max. The mitral regurgitant volume is then determined by multiplying the ERO by the VTI of the mitral regurgitant jet: Regurgitant Volume RVol (mL/beat) = ERO x VTI. Interpretation.
