  • Page 7: Precautions For Use

    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...
  • Page 8 • 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.
  • Page 9 • 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.
  • Page 10 • If the WristOx fails to respond as described, refer to “Troubleshooting” or discontinue use until the situation has been corrected by qualified personnel.
  • Page 11 • The WristOx is designed to determine the percentage of arterial oxygen saturation of func- tional 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.
  • Page 12 Unpacking and Inspecting the WristOx Contact the carrier immediately if the shipping carton for the WristOx is damaged. Confirm that the items listed below are packed with the WristOx: • WristOx™ Wrist Oximeter • Two 1.5V Alkaline N-cell Batteries • WristOx Operator’s Manual •...

  • Page 13: Indications For Use

    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.

  • Page 14: Installing The Batteries

    Installing the Batteries Use your thumb to loosen the lower front cover of the WristOx, and carefully remove the battery door by sliding it downward.
  • Page 15 Carefully re-position the battery door. Do not force the door into place; it fits only when positioned properly. If the WristOx does not turn on when a sensor is plugged into the unit, reinsert the batteries or refer to “Troubleshooting.”...

  • Page 16: Important Notes About Battery Use

    Important Notes About Battery Use The Battery Indicator will begin to flash approximately 30 minutes before entering critical battery mode. In critical battery mode, the WristOx no longer monitors or records patient data. Replace low batteries as soon as possible.
  • Page 17 The WristOx performs an automatic startup (initialization) sequence and self-test when a sensor is plugged in. Verify that all indicators display during the first phase of the startup sequence. If any indicator is not displayed, do not use the WristOx. Contact Respironics Customer Service for assistance.

  • Page 18: Attaching The Sensor

    Place the patient’s finger inside the sensor. Refer to the respective sensor instructions for specific information about placement and patient safety. Plug the sensor into the connector at the top of the WristOx, ensuring that all indicators appear during the first phase of the startup sequence.

    (indicated by the %SpO icon). Pulse Rate Display The pulse rate display is the lower numeric display on the left side of the WristOx (identified by the symbol). This 3-digit indicator display shows the pulse rate in beats per...

  • Page 21: Pulse Quality Indicator

    Pulse Oximeter Sensor Indicator The Pulse Oximeter Sensor Indicator indicates when a sensor has become disconnected, has failed, or has not been applied correctly. Pulse Strength Bargraph Indicator This 10-segment bargraph indicates pulse strength as determined by the oximeter. The height of the Pulse Strength Bargraph is proportional to the pulse amplitude.

  • Page 22: Battery Indicator

    Battery Indicator Any time the WristOx batteries are low or critical, this Indicator blinks, providing early warning to replace the batteries. After critical battery capacity is met, the display turns off and monitoring is stopped. Numeric Indicators Numeric Indicators appear after an %SpO or pulse rate reading is complete, providing results of the measurement.

    Respironics pulse oximeter models. NOTE: Data is stored in the WristOx regardless of which mode the device is in.
  • Page 24 In addition, information about device model number, revision, and parameters can be retrieved; patient data can be downloaded and stored; WristOx memory can be cleared; and the WristOx date and time can be synchronized to the date and time of the computer.
  • Page 25 %SpO and pulse rate data might add to patient anxiety in longer-term studies. In Partial Display mode, %SpO and pulse rate data are not displayed on the WristOx, but the Pulse Strength Bargraph is still visible.

  • Page 26: Activation Options

    Spot Check mode is the WristOx default activation setting. In Spot Check mode, inserting a finger in the sensor turns ON the WristOx automatically, and removing a finger turns OFF the WristOx automatically. In this mode, the sensor can be left attached (plugged in) to the WristOx.

  • Page 27: Sensor Activation Mode

    Sensor Activation mode can be selected with nVISION software (version 5.0 or greater). In this mode, connecting and disconnecting the sensor from the WristOx functions like an ON/ OFF switch (whether or not a finger is in the sensor). In Sensor Activation mode, the WristOx shuts off automatically after 30 minutes of no use or invalid pulse detection.
  • Page 28 Use the instructions below to connect the WristOx to a computer: Connect the cable to the appropriate COM port on the computer. Plug the cable to the top of the WristOx. Wait until CP appears in the WristOx display. The WristOx is now ready for use with nVISION software.

  • Page 29: Memory Features

    Only recording sessions longer than one minute are stored. Each time the WristOx is turned on, the current oximeter time and date (if the clock is set properly) are stored in memory to allow quick differentiation of recording sessions. Patient and pulse rate are stored every four seconds (default), or every one or two seconds if programmed using nVISION software (version 5.0 or greater).
  • Page 30 NOTE: Storage rates do not affect battery life; however, data storage capacity is reduced when using a 1- or 2-second storage rate. Using a 2-second storage rate, data storage capacity is reduced to approximately 16 hours. Using a 1-second storage rate, data storage capacity is reduced to approximately 8 hours. The stored pulse rate ranges from 18 to 300 pulses per minute.
  • Page 31 Clean the WristOx with a soft cloth dampened with isopropyl alcohol. Do not pour or spray any liquids onto the WristOx, and do not allow any liquid to enter any openings in the device. Allow the WristOx to dry thoroughly before reusing.
