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
