Indications for Use
Indications for Use
The Nonin WristOx2®, Model 3150 Pulse Oximeter is a small, wrist-worn device indicated for
use in measuring, displaying, and storing functional oxygen saturation of arterial hemoglobin
(%SpO2) and pulse rate. It is intended for spot-checking and/or data collection and recordingof
adult and pediatric patients, during both no motion and motion conditions, and for patients who
are well or poorly perfused. The intended use environments are hospitals, medical facilities,
ambulatory, subacute, and sleep study environments, and mobile units.
Warnings
Do not use this device in a Magnetic Resonance (MR) environment or in the presence of flammable anesthetics
or gases.
This device is not defibrillation proof per IEC 60601-1.
This device is intended only as an adjunct device in patient assessment. It must be used in conjunction with
other methods of assessing clinical signs and symptoms.
Check the pulse oximeter sensor application site every 4 hours to determine the positioning of the sensor
and the circulation and skin sensitivity of the patient. Patient sensitivity varies depending on medical status or
skin condition.
Avoid excessive pressure to the sensor application site as this may cause damage to the skin beneath the sensor.
Carefully route patient cables and connections to reduce the possibility of patient entanglement, strangulation, or
injury to the patient.
To avoid patient injury, use only Nonin-branded PureLight®pulse oximeter sensors. These sensors are
manufactured to meet the accuracy specifications for Nonin pulse oximeters. Using other manufacturers’
sensors can result in improper pulse oximeter performance.
To prevent improper performance and/or patient injury, verify compatibility of the monitor, sensor(s), and
accessories before use.
No modifications to this device are allowed as it may affect device performance.
The USB cable must be unplugged from the device before replacing batteries.
Before changing the batteries, make sure the device is off and the sensor is not applied to a digit.
This device should not be used adjacent to or stacked with other equipment. If adjacent or stacked use is
necessary, the device should be observed carefully to verify normal operation.
The use of accessories, sensors, and cables other than those listed in this manual may result in increased
electromagnetic emission and/or decreased immunity of this device.

• The battery indicator blinks.
• The device no longer monitors or records patient data.
• The clock settings are lost.
• The device reverts to Spot Check mode.
When batteries are removed in low battery mode, the device maintains the time and date for up
to 30 seconds. After battery replacement, check the device’s screen during startup to ensure
dateandtime areset.Use nVISIONsoftwaretosynchronize theclockandchange theoperation
mode (see “Accessing nVISION Settings” on page 29).
Remove the batteries and disconnect the sensor if the device is to be stored for more than
1 month. In storage, battery life is approximately 9 months.
NOTES:
• This device contains non-volatile memory. Removing or replacing batteries does not affect
the data stored in memory. Stored data remains in memory until overwritten by newer data
or cleared from memory with nVISION software (version 6.3 or greater).
• If batteries are replaced while recording data, the session will terminate and some data
from the session may not be saved. The terminated session will be time stamped with the
current date/time the next time the device turns on.
• To avoid potential battery cell damage for all battery types, remove batteries from the
device when the critical battery indicator displays. Leaving rechargeable batteries in the
device during critical battery will decrease battery life.
• If clock settings are lost, the date and time restarts at 01:01:10:00:00.
Bluetooth Technology
Bluetooth technology allows wireless connections between electronic communications and
computing devices. The technology is based on a radio link that offers fast and reliable data
transmissions. Bluetooth uses a license-free, globally available frequency range in the ISM
band—intended to ensure communication compatibility worldwide.
Nonin’s use of Bluetooth wireless technology allows SpO2and pulse rate data to be transmitted
through a Bluetooth radio to a compatible Bluetooth-enabled device. Nonin’s wireless system
removes the cable connection from the device, giving patients increased ability to move freely.
To make efficient use of battery life, Nonin’s WristOx2, Model 3150, uses an automatically
switchable Class 1/Class 2 Bluetooth radio with a maximum range (spherical radius) of about
100 meters (328 feet). Obstacles and other conditions may affect range, and class of operation
and connection mode will impact battery life. See “Specifications” for detailed battery life
information.

Operation Modes
Operation Modes
The WristOx2, Model 3150, has three states: Cable, Standby, and On.
Cable
The device is in Cable mode when it is connected to a PC using the USB interface cable. While
in Cable mode, the device does not collect or save data and the Bluetooth radio is off.
NOTE: To save battery life, the Model 3150 will automatically shut off after 60 minutes
when it is connected to a PC using the USB interface cable.
Standby
When the device is in Standby mode, the screen is blank and the device appears to be off. In
Standby, it is ready for a signal that will turn the device on (e.g., pressing activation switch,
inserting finger in sensor [Spot Check mode], connecting sensor [SensorActivation mode], or
programmed start time [Programmed mode]). While in Standby mode, the device does not
collect or save data and the Bluetooth radio is off.
On
When the device is on, it can collect and save data. The device features three turn on modes:
• Spot Check mode
• Sensor Activation mode
• Programmed mode
The device is delivered in Spot Check mode. nVISION software (version 6.3 or greater) is
needed to access the device settings and change Spot Check mode to Sensor Activation or
Programmed mode (see “nVISION Software”). nVISION software (version 6.4 or greater) is
needed to access memory volume (MVI) display mode.
The device recalls the active settings when the device is shut off and turned on again.
Spot Check Mode
Spot Check mode is the default turn on operation mode.
The device automatically turns on when a finger is inserted into the sensor. It enters Standby
mode 10 seconds after the finger is removed. If the sensor is disconnected, the device enters
Standby mode immediately.
In this mode, the sensor can be left connected to the device.
NOTE: If the device determines that a sensor fault exists (a sensor failure, misalignment,
or incompatibility with the device) or if a pulse oximeter sensor signal cannot be detected,
the device enters Standby mode after 3 minutes.
