Precautions for Use
Read and follow all safety instructions before using the WristOx.
Contraindications
• Do not use the WristOx in a magnetic resonance imaging (MRI) environment.
• Explosion Hazard: Do not use the WristOx in an explosive atmosphere or in the presence
of flammable anesthetics or gases.
Warnings
• Read this entire manual carefully before using the WristOx.
• The WristOx is intended only as an adjunct in patient assessment. It must be used in conjunction with other methods of assessing clinical signs and symptoms.
• General operation of the WristOx might be affected by the presence of an electrosurgical
unit (ESU).
7
• As with all medical equipment, carefully route patient cables and connections to reduce the
possibility of patient entanglement or strangulation.
• Use the WristOx only within the specified temperature ranges: +32°F to +122°F (0°C to
50°C) for operating, and 14°F to 122°F (-10°C to +50°C) for storage and transportation.
• Use only Respironics-manufactured pulse oximeter sensors. These sensors are manufactured to meet the accuracy specifications for Respironics pulse oximeters. Using other
manufacturers’ sensors can result in improper pulse oximeter performance.
• Discontinue use of adhesive tape strips if the patient exhibits an allergic reaction to the
adhesive material.
• Do not stretch the adhesive tape while applying the pulse oximeter sensor.
• Ensure that the wrist band fits comfortably on the patient’s arm. Do not over-tighten the
wrist band.
• Pulse oximeter readings might be affected while patients are being defibrillated.

Cautions
• U.S. federal law restricts this device to sale by or on the order of a physician.
• Before using any sensor, carefully read the Directions for Use.
• Do not, under any circumstances, perform any testing or maintenance on the WristOx
while it is being used to monitor a patient.
• Verify that all visible indicators appear during the start-up (initialization) sequence. If any
indicator does not appear, do not use the WristOx. Contact Respironics Customer Service
for assistance.
• This equipment complies with International Standard EN 60601-1-2:2001 for electromagnetic compatibility for medical electrical equipment and/or systems. This standard is
designed to provide reasonable protection against harmful interference in a typical medical
installation. However, because of the proliferation of radio-frequency transmitting equipment and other sources of electrical noise in healthcare and other environments (for example, cellular phones, mobile two-way radios, electrical appliances), it is possible that high
9
levels of such interference due to close proximity or strength of a source might disrupt the
performance of this device.
• If the WristOx fails to respond as described, refer to “Troubleshooting” or discontinue use
until the situation has been corrected by qualified personnel.
• Do not remove any covers other than the battery cover when replacing batteries. There are
no user-serviceable parts inside.
• Batteries might leak or explode if used or disposed of improperly.
• Follow local governing ordinances and recycling instructions regarding disposal or recycling of the device and device components, including batteries.
• Do not immerse the WristOx or sensors in water or any other liquids.
• Do not place or pour liquids on top of the WristOx.
• The WristOx is a precision electronic instrument. It must be repaired by trained
Respironics personnel only.
10
• The WristOx is designed to determine the percentage of arterial oxygen saturation of functional hemoglobin. Significant levels of dysfunctional hemoglobin may affect the accuracy
of the measurement.
• The WristOx might misinterpret motion as good pulse quality. Minimize patient motion as
much as possible, or change the type of sensor being used.
• Check the pulse oximeter sensor application site frequently 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.
• Cardiogreen and other intravascular dyes, depending upon their concentrations, might
affect the accuracy of the SpO
measurement.
2
• Some nail polish colors or artificial nails can reduce light transmission and affect SpO2
accuracy.

Using the WristOx
Indications for Use
The Respironics® WristOx™ pulse oximeter is a small, wrist-worn device indicated for use in
measuring, displaying, and storing functional oxygen saturation of arterial hemoglobin (SpO
and pulse rate. It may be used for spot-checking and/or data collection and recording of adult
and pediatric patients in hospitals, medical facilities, ambulatory, subacute, and sleep study
environments.
WARNING! Do not use the WristOx when alarms are required!
The WristOx comes packaged in Spot Check mode. In Spot Check mode, inserting a finger in
the sensor turns on the WristOx automatically, and removing a finger turns off the WristOx
automatically. Advanced memory and programming features are only available with
nVISION
