Section 1
Introduction
This manual describes the use and operation of the Model 511 Pulse Oximeter, from
Novametrix Medical Systems Inc.
The Model 511 is a lightweight, easy to use, pulse oximeter that provides reliable
measurement and displays for functional pulsatile oxygen saturation (SpO2) and pulse rate.
The monitor is powered from four standard AA size alkaline batteries, or may be connected
to an optional external power source for continuous mains operation.
Numerical SpO2 and Pulse Rate information is presented on a liquid crystal display (LCD).
A pulsatile signal activity bar, battery strength indicator, and general alarm indicators are
also displayed on the LCD. The Model 511 controls include a power on/off switch that also
controls display illumination, and an alarm key that enables/disables audible alarms, and
sets alert limits.
Model 511 monitors (Cat. No. 6416-00) are available with a serial communications option
which allows patient trend information to be downloaded into the Novametrix NovaCARD
Data Archive System or other communicating devices. Interfacing between the
communicating device and the monitor is via a simple cable connection. See “Serial
Communication Option” on page 23 for more information.
Principles of Operation
The Model 511 measures oxygen saturation and pulse rate with sensors that contain red and
infrared light sources, called LEDs. Since oxygen saturated blood absorbs different
amounts of light at each wavelength (red and infrared) as compared to unsaturated blood,
the amount of light absorbed by the blood in each pulse can be used to calculate oxygen
saturation.
The light energy from red (660 nm) and infrared (940 nm) LEDs is beamed through a
sample cell—a pulsating vascular bed, the patient’s finger or toe for example. The
remaining light energy not absorbed by the sample cell reaches a light receptor, called a
photodiode, on the opposing side of the sensor. The data received at the photodiode is sent
back to the monitor where it is split into its red and infrared components, digitized,
processed by a microprocessor chip, and finally displayed as a numerical value for oxygen
saturation and a plethysmogram.
The Model 511 is calibrated to display “functional” saturation. This differs from the
“fractional” saturation value displayed by most co-oximeters. Functional saturation
represents the amount of oxyhemoglobin as a percentage of the hemoglobin that can be

oxygenated. Dysfunctional hemoglobins (COHb and METHb) are not included in the
measurement of functional saturation.
Calculating Functional Oxygen
Saturation
Functional Saturation =
HbO2 = Fractional Hemoglobin
HbO2
COHb = Carboxyhemoglobin
100 - (COHb + METHb) METHb = Methemoglobin
Pulse Rate is calculated by measuring the time interval between the peaks of the infrared
light waveform. The inverse of this measurement is displayed as pulse rate.
The Model 511 must be used in conjunction with OxySnap SuperBright™ saturation
sensors.
Indications and Usage
The Model 511 Pulse Oximeter is intended to be used for monitoring of oxygen saturation
and pulse rate. The Model 511 is designed to monitor all patient areas including adult,
pediatric and neonatal.

Section 4 Monitor Operation
2. To display limits without setting new limits if audio is enabled, press and release the
alarm key twice. The first press turns off the alarms and the second turns them
back on and causes the high and low limits to be displayed for three seconds. The
monitor will then return to normal operation.
3. To display limits without setting new limits if the audio is disabled (audible alert icon
visible), press and release the alarm key. The high and low limits will be displayed
for three seconds before the monitor returns to normal operation. Press and
release the alarm key to disable the audible alarms.
Battery Life
The Model 511 displays a battery icon to indicate:
•
fully charged batteries, over 4 hours of battery life
•
less than 4 hours of battery life
•
indicates less than 2 hours of battery life
•
(flashing) less than 15 minutes of battery life
When the battery voltage reaches the 2 hour level
, the battery is very low. As the battery
reaches near depletion, the battery icon will flash at a rate of once per second, and the alert
audio will sound, this alert tone cannot be muted (even if alerts are disabled). Continued
use of the monitor at this point will result in the monitor shutting itself off.
NOTE: The above information is based upon normal monitoring conditions (e.g. sensor
on patient, new alkaline batteries). Use of non-alkaline, previously used alkaline, or
rechargeable alkaline batteries will affect the battery life times. Prolonged use of the
backlight can significantly reduce overall battery life.
The battery icon may appear fully charged for the first minute after power up, after which
it will reflect the true battery charge.
NOTE: When operating from the external power supply the battery icon does not reflect the
condition of the batteries. See “External DC Supply”.
Select and Apply a Sensor to the Patient
Refer to Section 5.
Monitoring Saturation and Pulse Rate
Once the Model 511 is powered on and a sensor is connected to the monitor and properly
applied to the patient, numerical SpO2 and Pulse Rate values appear on the monitor’s
display. A “pulse activity bar”, derived from the pulsatile signal, is also displayed. The
monitor automatically adjusts the activity bar’s length to produce an easily visible display.
Verify the pulse activity bar reflects the patient’s pulse. The bar should show regular
rhythmic movement. Erratic or non-rhythmic pulse bar activity may indicate a poorly
positioned or applied sensor, or may be indicative of excess patient movement at the sensor
site. Check the sensor site and if necessary, attempt to reduce patient movement.
Violation of the upper or lower saturation auto alert limits shall immediately cause a “H”
or “L” to flash within the borders of the display alarm icon, even if the icon itself is
disabled.

Model 511 User’s Manual
Alerts
If the Model 511 cannot detect “valid” saturation data with which to update the display, the
previous contents of the display shall be “held”. Should the display be held for more than
ten seconds, a “-” character will start to flash within the borders of the display alarm icon,
even if the alarm icon itself is disabled. If the Model 511 cannot detect valid pulsatile data
from the sensor within sixty seconds, the saturation and pulse rate displays will blank out
(display “--” and “---” respectively). If the display is held longer than ninety seconds the
Model 511 will emit an audible unlatched alarm (if enabled) and REPOSITION SENSOR
along with the number 9 will appear in the display. If at any time the monitor processes
valid data with which to update the display, the “-” will stop flashing, the display will be
updated, the timer reset to zero (seconds), and the audible alarm, if active, will be reset.

site often for adequate circulation—at least once every four hours.
Ensure that the sensor heads are directly opposite each other through the tissue. This
prevents the sensor from being placed on a site too thick (high arch) for proper operation.
Position the sensor so that the tape does not extend over the space between the fingers or
toes to insure there will be no light transmission through this space.
6. To maximize sensor life, secure the sensor to the patient with additional tape.

Serial Communication Option
Model 511 monitors (Cat. No. 6416-00) are available with a serial communications option
which allows patient trend information to be downloaded into the Novametrix NovaCARD
Data Archive System or other communicating devices. A 15-pin mini-D connector
(PATIENT/SERIAL INTERFACE) on the top panel indicates the option is installed. An interface
cable (Novametrix Cat. No. 6493-01) is required for connection between the monitor and
the communicating device.
The PATIENT/SERIAL INTERFACE connector is shared between patient monitoring and serial
communication. When attaching a sensor for patient monitoring, the 6292-01 cable must
be connected to the PATIENT/SERIAL INTERFACE, the sensor will plug into the other end of
the cable. When utilizing the monitor for serial communication the 6293-01 interface cable
must be used, this cable terminates in a 9 pin D female for connection to the communication
device.

Model 511 User’s Manual
NOVACOMM1 Interface
NOVACOMM1 Interface
The NOVACOMM1 interface is designed to output data in formats easily read by a computer
or data logging device. The computer interface provides the user the ability to “dump” trend
information to a computer file for later analysis. The communication format is 9600 baud,
8 bits, no parity, 1 stop bit and XON/XOFF handshaking.
Trend Dump
Trend data is transmitted as a succession of records. The record size for Model 511 is 16
bytes of ASCII Hexadecimal data. A record can be one of two types, an INFO record or a
DATA record. The INFO record contains monitor information such as time of day, date,
limit settings, and units. The DATA record contains event marker, audio disable, SpO2, and
pulse rate values.
The first record sent is always an INFO record. This record reflects the oldest data in the
buffer, then records would continue being sent in chronological order from the oldest record
to the newest record. In normal monitoring use, an INFO record would be followed by 15
data records, followed by another INFO record and then another 15 data records, etc.
Turning the monitor off, or changing the limits will disrupt this sequence. When this occurs
a new INFO record will be sent and indicate the time and date, along with the current limits.
At this point, unless another exception occurs, the next INFO record will be followed by 15
DATA records.
An INFO record can be distinguished from a DATA record by the first byte. The first byte
of an INFO record is FF, the first byte of a DATA record is 00-C8 (0-200 decimal), or FB
(pen lift or no data available). Any other values are not applicable. The DATA record uses
8 data points per parameter, at 8 second resolution, for a total of 64 seconds of trend data
per data record.
To request trend dump, the computer must send an ASCII “6” character. The monitor
echoes back the “6” character and transmits the first INFO record.
The Mode 6 data format is;
INFO record;
byte 0

Date and Time
Date and Time mode causes the Model 511 to transmit, on request, the date and time as
calculated by the monitor’s internal calendar clock.
To request the date and time, the computer must send an ASCII “d” character. The monitor
echoes back the “d” character and sends the date and time on the same line. The Mode d
data format is;
d•MMM/DD/YY•hh:mm:ss<cr><lf>
where;
d - the echoed command character
• - is an ASCII space character
MMM - a 3-character month (Jan, Dec),
DD - a 2-digit ASCII day (01, 31),
YY - the last 2-digits of the year (1990 is 90),
hh - a 2-digit hour based on a 24 hour clock (00, 23),
26
01-May-96
Model 511 User’s Manual
NOVACOMM1 Interface
mm - a 2-digit minute,
ss - a 2-digit second,
<cr><lf> is a carriage return, line-feed sequence.
Setting Date and Time
To set the date and time the computer must send the ASCII “s” character. The “s” is the
command to set the time. The mode of the data format is;
sMM/DD/YY•hh:mm:ss
where;
• - is an ASCII space character
s - the echoed command character
MM - a 2-digit month number (01, 12),
DD - a 2-digit ASCII day (01, 31),
YY - the last 2-digits of the year (1990 is 90),
hh - a 2-digit hour based on a 24 hour clock (00, 23),
mm - a 2-digit minute,
ss - a 2-digit second.
There must be a delay of at least 20 msec between bytes so the data receive buffer will not
overflow. When the monitor has received the complete command it will echo the date in the
format described in the section above.
Clear Trends
Clear Trends mode allows the user to remotely clear the Model 511 trend memory This
action has the same result as the monitor’s Clear Trend function in that trend memory and
the Trend Page displays are cleared.
Use this remote Clear Trends function with care as there is no way to undo the clear
command once issued.
To clear the Model 511 trend memory, the computer must send an ASCII “c” character. The
Model 511 will echo the “c” followed by a <cr><lf> and then the trend memory will be
cleared.
Exit Command
To exit the NOVACOMM1 mode, the computer must send an “x” or “X” character. The
Model 511 will echo the “x” and then stop communication. Sending a new valid command
character will start communication again.
