Abstract

The volume/pressure (V/P) curve of the total respiratory system in paralysed patients is drawn assuming that volume changes of the respiratory system (ΔV resp) equals volume displacement of the measuring apparatus (ΔV syr), usually a supersyringe. However, in 93 VP curves we found that O2 removed from the lung-syringe system during the procedure (proportional to the time) largely exceedes the CO2 added to the lung-syringe system (ΔV gas). This results in a net loss of volume from the system (ΔV resp
