The system processor uses external memory for operation. There is a
512K x 8 static RAM for temporary data storage.
127(The static RAM is not battery bac ked-up, therefore this device is
not a transportable patient monitor such as the TRAM module.
The static RAM is also used as temporary storage of Masimo MS-3
program code during program download of the MS-3 software. The
program code is stored in a 128K x 8 sectored FLASH EPROM. This
device can be erased on an individual sector basis. The first sector of
FLASH is used for storing the BOOT code. This insures that even if a
download of code fails the module still attempts another download of
code. The other seven sectors of FL ASH store the MAIN code. The MAIN
code operates during normal operation of the module. This code can be
updated using the host patient monitor.

Masimo MS-3
The principles of operation of the Masimo MS-3 pulse oximeter is that
oxyhemoglobin and deoxyhemoglobin differ in their absorption of red and
infrared light (spectrophotometry), the volume of arterial blood in tissue
(and hence, light absorption by that blood) changes during the pulse
(plethysmography), and that arterio-venous shunting is highly variable
and that fluctuating absorbance by venous blood is a major component of
noise during the pulse. Because oxyhemoglobin and deoxyhemoglobin
differ in light absorption, the amount of red and infrared light absorbed
by the blood is related t o hemoglobin oxygen saturati on. The Masimo
MS-3 pulse oximeter decomposes the red and infrared pulsatile
absorbance signal into an arterial signal plus a noise component and
calculates the ratio of the arterial signals without noise. The ratio of the
two arterial pulse-added absorbance signals and its value is used to find
the SpO
MS-3’s software.

communication processor performs this function, operating in slave mode
it receives clock and enable signals from the host patient monitor.
All integrated circuits with signals connected to the backplane are
powered directly from the backplane +5 volts not the soft-started power
supplies. This is so the signals won’t load down the synchronous Serial
Shift Register Interface S ignals upon insertion of the module.
Power Condition and Soft Start
The Masimo module receives power from the host Tram- rac. The module
is designed for insertion into a live Tram-rac. All the power supply pins
incorporate soft-start circuitry to limit inrush currents. This module uses
the +5V and +16.5V power supplies from the host patient monitor.
Isolated Power Supply
The Masimo module uses an isolated power supply to power the Masimo
MS-3 board. The power supply is designed to provide 4000 volts of
patient isolation from the host patient monitor. The isolated power
supply generates +5V, +15V, and -15V and is controlled by the system
processor.
The system processor moni tors signal PS_FAULT whic h indicates a fault
condition with the power supply. If this signal is active (logic high) for
more than 200ms, the system processor shuts down the isolated power
supply. The system processor does not monitor this line for the first
100ms after the power supply is enabled allowing the isolated power
supply time to stabilize.
Patient Connector Flex Circuit
The flex circuit a ssemb ly p r ovide s t he conn ectio n fro m t he Masi mo MS-3
analyzer to the patient receptacle on the front panel of the module. The
Masimo Flex PCB includes a ferrite core to reduce electromagnetic
emissions/susceptibility and a shield around the front panel connector to
reduce susceptibility to external interference.
