  • Sa,O2: arterial oxygen saturation

  • n: number of responders

  • #: the number of responders decreased throughout the test

  • : was not included in the statistical analysis

  • There were significant difference between all countries for target Sa,O2 level (p<0.001), while time in which target level Sa,O2 must be achieved, was not significantly different between all countries (p=0.39)
