Functional Description
Overview
This chapter contains functional descriptions of the components contained in the Propaq M and
the Propaq M options.
Circuit Distribution
The Propaq M unit consists of one key PCB assembly, the Monitor Board, as well as a few
modules and assemblies: the Front Panel Keypad assembly, Status LCD Board, Dock
Connector Board, and Display. The NIBP, CO2, and SpO2 circuitry reside on modules that
connect to the Monitor Board.
Monitor Board
The Monitor board integrates the analog circuitry and interface circuitry for patient parameters,
a digital processing section as well as user interface controls, audio control, and power circuitry
for the entire system and charging circuitry for the battery. The Propaq M system relies on a
centralized dual processor engine for its computing needs. The Main Processor (MP) serves as
the primary user interface engine and provides connectivity needs, while the Patient Processor
(PP) controls the patient monitoring function. An additional power controller micro-controller
(PC) controls the power sequencing, and battery/charger interface.
