Design Considerations

A portable blood gas analyzer is an instrument used for measuring partial pressures of oxygen, carbon dioxide, carbon monoxide, and nitrogen in blood.

The core subsystems include:

  • Analog Front End
    Multiple chemical sensor inputs are conditioned, multiplexed, amplified and digitized for processing.
  • Microcontroller
    Executes blood gas measuring processes and controls interface with memory and peripheral devices.
  • LCD
    Data display
  • Power Management
    Converts the input battery power to run various functional blocks.
  • Analog Feedback Loop
    Converts and conditions digital output from MCU to analog signal for self calibration at the sensor input stage.
