title: Clinical and economic performance criteria for intraarterial and extraarterial blood gas monitors, with comparison with in vitro testing.
abstract: The frequency with which blood gas measurements should be obtained is controversial because laboratory-based blood gas analyzers impose blood loss, delay, and cost on each measurement. Point-of-care analyzers eliminate the delay factor, but blood loss and cost factors remain. Optode microsensing can be adopted readily to in vivo monitoring devices that can provide continuous or on-demand blood gas values that do not result in blood loss or added cost to each measurement. This article critically reviews the advantages and limitations of optode-based blood gas monitors based on published data. In addition, a basis for considering the economic effects of extralaboratory blood gas measurement devices (point-of-care analyzers and optode-based monitors) is presented.
