Mainstream CO
chamber (commonly referred to as the "bench") is an integral part of the Mainstream
sensor which is located in-line, between the patient's airway and the ventilator circuit
via an airway adapter. The patient's expired gas is sampled directly from the patient's
airway. The MSP Board interfaces the external Mainstream sensor to the monitor.
Sidestream CO
the Stick Board within the monitor. A sample of the patient's expired gas is aspirated
from the airway and is drawn to the bench through a sampling line containing a water
trap. The Stick Board also contains pneumatic tubing that connects to the SSP Board.
The Stick Board is mounted on the Sidestream Processor Board assembly (SSP
Board) which interfaces the Stick Board to the monitor. The SSP/Stick Board assembly
is mounted within the front bezel of the Expansion Module housing of the monitor.
System Interface. The SSP Board power and communication is obtained via the extender
board that connects to the MSP Board. The extender board routes datalines from the
MSP Board and contains additional power supplies for powering the SCO
