  • Method of making a blood gas/electrolyte control
    Patent number: 5518929
    Abstract: Aqueous solutions containing buffers and electrolytes are adjusted to levels required for calibration of both blood gas analyzers and ion selective electrolyte analyzers. A control material, composed of similar matrix, is adjusted to three levels of blood gas and electrolyte conditions. These quality control materials are used to monitor blood gas/electrolyte laboratory instrumentation.
    Type: Grant

  • Blood gas control
    Patent number: 4458021
    Abstract: Disclosed are cell-free, stable, aqueous blood gas controls containing a proteinaceous foaming agent. The addition of foaming agent to the blood gas control permits generation of a gas impermeable foam within the head space of a sealed ampule in which the control is packaged. Upon agitation of the ampule prior to opening, the foam thus generated effectively isolates the control fluid from the ambient environment, thereby maintaining the concentration of gases dissolved within the fluid at their assigned values.
