Section 3 —Theory of Operation
NIBP Module
(pn 93947A003)
This module connects to the Main Board. The upgraded NIBP
algorithm firmware installed conforms to EN1060.
DOX Module
(pn 91391A001)
This module is the Criticare Digital Oximetry circuit. The circuitry is
configured in a physical geometry to be compatible with the Nellcor
OxiMax
®
and Nellcor Carrier Board real estate. In this manner the
DOX module and the Nellcor SpO
2
module fit in the same location
within the 506N3 enclosure and utilize the same cable assembly to
connect to the Main Board. Additionally, the DOX Module provides
electrical isolation of 1500VAC minimum through power and serial
interface connections. The DOX SpO
2
sensor connector is mounted
directly onto the Module.
Nellcor Module
(pn 83459B001/2)
The Nellcor pulse oximetry module is a small printed circuit board
assembly that provides the core components of a low power pulse
oximeter system with OxiMax performance. It is designed for OEM
use and supports the full line of Nellcor OxiMax sensors, including
the new MaxFast™ forehead sensor.
Nellcor OxiMax technology is a system that uses calibration data
contained in Nellcor brand OxiMax sensors when calculating the
patient’s SpO
2
. Using calibration data from the individual sensor
rather than the pulse oximeter board significantly improves the
accuracy of the information because the calibration coefficients used
in the calculations are tailored to the information detected in the
sensor.
Nellcor Carrier Board
(pn 91387A001)
The Nellcor Carrier board is designed to allow the Nellcor MP100
OxiMax module to mount directly on top in a mother/daughter board
arrangement. The Nellcor Carrier board provides electrical isolation
of 1500VAC minimum through power and serial interface
connections. The Nellcor sensor connector is mounted directly onto
the Carrier Board.
