Outcome Measures

Primary Outcomes (1)

  • Diameter of vein

    measurement of vein Diameter by ultrasound in a randomized order

    only 1 day (the day of the measurement); no follow-up is required

Study Arms (1)

ultrasound measurement

measuring subclavian vein Diameter in six Groups: neutral positioning, PEEP 0 cm H2O, neutral positioning, PEEP 5cm H2O, neutral positioning, PEEP 10cm H2O, Trendelenburg positioning -20°, PEEP 0 cmH2O, Trendelenburg positioning -20°, PEEP 5 cmH2O, Trendelenburg positioning -20°, PEEP 10 cmH2O After these measurements a central venous catheter is used to measure the central venous pressure.
