Christopher Reeve, our inspirational Chairman,
passed away on October 10, 2004 from heart
failure
CNN News Reeve went into cardiac arrest
Saturday at his home in Westchester County, New
York, after developing a serious systemic
infection during treatment for a pressure wound.
He slipped into a coma and died Sunday afternoon
at a hospital near his home

Tissue perfusion is modified in sepsis
  • Vascular hyporeactivity and vasoplegia
  • inductible NOS ?
  • Catecholamine misuse
  • Endogenous (epinephrine, norepinephrine,
    vasopressine)
  • Exogenous
  • Perfusion heterogeneity
  • SVR is only a global estimation
  • Modifications in tissue distribution and/or use
    of O2
  • Interstitial oedema (O2 diffusion abnormalities)
  • Hypoperfusion
  • Mitochondrial dysfonction

ScVO2 monitoring in ICU
Rivers et al. Current Opinion in Critical Care
2001 7 204-211
Factors that may influence SvO2 / ScvO2 value
  • Global indice of O2 extraction
  • if SaO2 1 ? SvO2 1 EO2
  • of no interest when severe hypoxemia and/or
    large variations of SaO2

Comparison of central-venous to mixed-venous
oxygen saturation during changes in oxygen
supply/demand
Reinhart et al. Chest 1989 95 1216-1221
  • Its not the same value but
  • Evolution is similar
  • Overestimation of SvO2 by ScvO2

    adults

    cardiac output despite fluid resuscitation.
  • Continue to titrate vasopressor to mean arterial
    pressure of 65 mm Hg or greater.

39
Inotropic Therapy
  • Do not increase cardiac index to achieve an
    arbitrarily predefined elevated level of oxygen
    delivery.
