4.9 Oxygen Saturation Modules, E-NSAT, E-NSATX,
M-NSAT, M-OSAT
N/OSAT
NOTE: Preamp Error is indicated on the service menu,
even though module contains MP-204 board.
NOTE: The status and error indicators are not valid
for the M-OSAT, E-NSAT and the M-NSAT..04 revision.
SAT Data
PR shows the pulse rate value [bpm] calculated from
the pleth.
SpO
% shows the oxygen saturation value
2
multiplied by 100.
Next are listed the messages that are sent from the
module to the monitor. Digit '0' means that the
message is not active, '1' is for the active one.
Preamp Error indicates 'Yes' if the Preamp
(MP-203(4)) board detects an error.
QUART Error indicates 'Yes' if an error is detected in the operation of QUART that is located in the Interface
board.
I/O Error indicates 'Yes' if an error occurs in the communication between Preamp (MP-203(4)) and Interface
board.
Timeouts is a cumulative number that indicates how many times the module has not responded to the
monitor's inquiry.
Bad checksums is a cumulative number that indicates how many times communication from the module to
the monitor has broken down.
Bad c-s by mod is a cumulative number that indicates how many communication errors the module has
detected.
The monitor starts counting these items at power up and resets to zero at power off. The nonzero values do
not indicate a failure, but the continuous counting (more than 5 per second) indicates either a serial
communication failure, or a module not in place. Also failures in other modules may cause these numbers to
rise or be set to 32769.
ROM indicates whether the checksum in the EPROM is in accordance with the one the software has
calculated.
The state is either OK, Fail or ? (module not in place or a communication error).
