•a Pulse Amplitude blip bar
• functional icons
• current measured %SpO
Symbols, Controls, Displays, and Indicators
2 (oxygen saturation
2
• pulse rate
OXIMax N-65 Operator’s Manual 19
Symbols, Controls, Displays, and Indicators
Decimal points after the %SpO2 or pulse rate indicate
that the respective limits have been changed from the
power-on default values.
There are various matrices within the signal processing
algorithm. Some of these are used to assess the severity
of conditions presented to the monitor in SpO
2 and pulse
rate measurements on a patient. Individual matrices, or
combinations of them, are used to drive the icon
indicators on the monitor front panel.
The signal processing algorithm increases the amount of
data required for measurements of SpO
2 and pulse rate
dependent on the measurement conditions. Throughout
normal measurement conditions, the averaging time is six
to seven seconds.
The signal processing algorithm extends the amount of
data required beyond seven seconds for measurement
conditions in which incoming signal quality is degraded,
such as:
• low perfusion
• active patients
• ambient light
• electromagnetic interference (EMI)
If the resulting dynamic averaging time exceeds 20
seconds, the Pulse Search indicator appears and SpO
2
and Pulse Rate displays continue updating every second.
As these conditions extend, the amount of data required
continues to increase.
If the dynamic averaging time reaches 40 seconds, the
Pulse Search indicator flashes and the SpO
2 and pulse
rate displays flashing zeros to indicate a loss-of-pulse
condition.
20 OXIMax N-65 Operator’s Manual
Symbols, Controls, Displays, and Indicators
Selected display elements, such as, icons or numerals,
may flash. There are three flash rates. See Table 1.

• flashes the SpO
2 value when the SpO2 is outside
the alarm limits
• shows a decimal point (.) after the SpO
2 value
(98.0), if alarm limits have changed from their
power-on defaults
Pulse Amplitude indicator (blip bar). Indicates the
dynamic pulse amplitude and rate. As the detected pulse
becomes stronger, more bars light with each pulse. The
reverse is true for weak pulses.
When setting alarm volume, the Pulse Amplitude blip
bar reflects the alarm volume setting.
OXIMax N-65 Operator’s Manual 21
Symbols, Controls, Displays, and Indicators
Pulse Rate display:
• shows the pulse rate in beats per minute
• flashes throughout loss-of-pulse alarms and when
the pulse rate is outside of the alarm limits
• shows two dashes throughout Sensor Disconnected
and Sensor Off Patient conditions
• shows pulse rates outside of the pulse rate range
(0, 20 to 300 bpm) as the closest value within the
range
• shows a decimal point (.) after the BPM value
(123.), if alarm limits have changed from their
power-on defaults
Low Battery indicator. Flashes when 15 or fewer
minutes of battery capacity remain. The indicator
displays constantly when the battery capacity reaches
critical condition at which time the monitor indicates an
error condition and shuts down.
Alarm Silenced indicator. Displays when audible alarms
have been silenced. It flashes when the audible alarms are
disabled.
Interference indicator. Lights when the N-65 algorithm
detects the incoming signal quality is degraded.
Degradations can be caused by ambient light, electrical
noise, electrosurgical interference, patient activity, or
other causes. An intermittently lit Interference indicator
is common during patient monitoring, and indicates that
the N-65 algorithm is dynamically adjusting the amount
of data required for measuring SpO
2 and Pulse Rate.
When lit continuously, it indicates the N-65 algorithm
has extended the amount of data required for measuring
SpO
2 and Pulse Rate and, consequently, fidelity in
tracking rapid changes in these values may be reduced.
See Front Panel Description on page 9.

Performance Considerations
WARNING: Pulse oximetry readings and pulse
signals can be affected by ambient environmental
conditions, O
patient conditions. See the appropriate sections of the
manual for specific safety information, such as Safety
Information on page 1 and OXIMAX Sensors and
Accessories on page 71.
Performance Verification
The performance of the OXIMAX N-65 is verified by
following the procedures outlined in the Performance
Verification section of the monitor service manual.
Qualified service personnel should perform these
procedures before using the monitor for the first time in a
clinical setting.
XIMAX sensor application errors, and
OXIMAX N-65 Performance Considerations
This section describes patient conditions that can affect
the monitor’s measurements.
OXIMax N-65 Operator’s Manual 87
Performance Considerations
Dysfunctional Hemoglobins
Dysfunctional hemoglobins, such as,
carboxyhemoglobin, methemoglobin, and
sulfhemoglobin, are unable to carry oxygen. SpO
readings may appear normal; however, a patient may be
hypoxic because less hemoglobin is available to carry
oxygen. Further assessment beyond pulse oximetry is
recommended.
Anemia
Anemia causes decreased arterial oxygen content.
Although SpO
patient may be hypoxic. Correcting anemia can improve
arterial oxygen content. The monitor may fail to provide
an SpO
2 if hemoglobin levels fall below 5 gm/dl.
Saturation
2
2 readings may appear normal, an anemic
The monitor displays saturation levels between 1% and
100%.
Pulse Rates
The monitor displays pulse rates between 20 and 300
beats per minute. The sensor accuracy ranges do not
apply to pulse rates above 250 bpm. Detected pulse rates
below 20 are shown as 0.

Performance Considerations
OXIMAX Sensor Performance Considerations
WARNING: Pulse oximetry readings and pulse signal
can be affected by ambient conditions, O
application errors, and patient conditions.
WARNING: Tissue damage can be caused by
incorrect application or inappropriate duration of use
of an SpO
site as directed in the O
2 OXIMAX sensor. Inspect the OXIMAX sensor
XIMAX sensor directions for
use.
WARNING: Use only Nellcor-approved OXIMAX
sensors and extension cables. Do not use cables more
than 4 feet in length. Use only the DEC-4 extension
cable or only the OXIMAX sensor.
XIMAX sensor
Inaccurate measurements can be caused by:
• incorrect application of the O
• placement of the O
XIMAX sensor on an extremity
XIMAX sensor
with a blood pressure cuff, arterial catheter, or
intravascular line
• excessive patient activity
• intravascular dyes, such as indocyanine green or
methylene blue
• externally applied coloring, such as nail polish or
pigmented cream
• failure to cover the O
XIMAX sensor site with opaque
material in high ambient light conditions
• venous pulsation
• dysfunctional hemoglobin
OXIMax N-65 Operator’s Manual 89
Performance Considerations
• low perfusion
Loss-of-pulse signal can occur for the following reasons:
•the O
XIMAX sensor is applied too tightly
• defibrillation
• a blood pressure cuff is inflated on the same
extremity as the one with the O
XIMAX sensor
attached
• there is arterial occlusion proximal to the O
sensor
• poor peripheral perfusion
• loss of pulse/cardiac arrest
To use the O
• Select an appropriate O
XIMAX sensor:
XIMAX sensor.
• Apply the sensor as directed, and observe all
warnings and cautions presented in the Directions
For Use accompanying the O
XIMAX sensor.
• Clean and remove any substances, such as nail
polish, from the application site.
• Periodically check to ensure that the O
XIMAX
sensor remains properly positioned on the patient.
XIMAX
High ambient light sources that can interfere with the
performance of an SpO
2 OXIMAX sensor are:
• surgical lights (especially those with a xenon light
source)
• bilirubin lamps
• fluorescent lights
• infrared heating lamps
• direct sunlight
90 OXIMax N-65 Operator’s Manual
Performance Considerations
To prevent interference from ambient light, ensure that
the O
XIMAX sensor is properly applied, and cover the
O
XIMAX sensor site with opaque material.
If interference due to patient activity presents a problem,
try one or more of the following to correct the problem:
• verify that the O
XIMAX sensor is properly and
securely applied
•move the O
• use an adhesive O
•use a new O
XIMAX sensor to another site
XIMAX sensor
XIMAX sensor with fresh adhesive
backing
• keep the patient still, if possible
If interference due to poor perfusion presents a problem,
consider using the MAX-R O
FAST O
XIMAX sensor. The MAX-R OXIMAX sensor
XIMAX sensor or the MAX-
obtains measurements from the nasal septal anterior
ethmoid artery, an artery supplied by the internal carotid.
These O
XIMAX sensors may obtain measurements when
peripheral perfusion is relatively poor.

Troubleshooting
WARNING: If you are uncertain about the accuracy
of any measurement, check the patient's vital signs by
alternate means; then make sure the O
functioning correctly.
WARNING: There are no user-serviceable parts
inside the O
removed by qualified service personnel.
Caution: Do not spray, pour, or spill any liquid on the
O
openings in the enclosure as this may damage the
monitor.
