Open Access Abstract Introduction It is possible that taking a static pressure-volume PV measurement could durably affect oxygenation and thus interfere with early evaluation of a therapeutic intervention delivered just after that measurement. The aim of the present study was to investigate the effects over time of a single static PV measurement on gas exchange and haemodynamics the PV measurements were taken using a super syringe and by using the constant flow method in patients with acute respiratory distress syndrome. Method We conducted a prospective randomized and controlled interventional study in an intensive care unit. The study was conducted in 17 patients with early acute respiratory distress syndrome ventilated with a tidal volume of ml kg a plateau pressure of 27 7 cmH2O and a positive end-expiratory pressure PEEP of 10 cmH2O. They were all evaluated for 1 hour after each of the following two measurements was taken and during a control period in a randomized order generation of a PV curve .
