Abstract :
Background: The current practice to measure RV is either by BPG or helium dilution methods which may not be available in all clinics due to their cost.
Methods: This paper outlines a method for both direct and indirect calculation of RV via PFT with acceptable sensitivity (81%,60%), specificity (71%, 94%) and validity (76%, 78%) for obstructive and restrictive lung disease respectively at a much lower cost.
