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 con-
junction 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).

• 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 manufac-
tured 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 electromag-
netic 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 equip-
ment and other sources of electrical noise in healthcare and other environments (for exam-
ple, cellular phones, mobile two-way radios, electrical appliances), it is possible that high

10
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 recy-
cling 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.
