Installing Batteries
Two 1.5-volt AAA-size batteries power the 9590 for about 6,000 spot checks or 36 hours of operation. Nonin recommends using alkaline batteries (included with each new device). When batteries are low, the numeric displays flash once per second. Remove batteries if the device will be stored for more than 30 days. Replace low batteries as soon as possible, using the instructions below.
WARNING: Before changing batteries, make sure the device is off and is not applied to a digit.
NOTE: Rechargeable batteries may be used; however, they require more frequent replacement.

1. Hold the 9590 as shown in Figure A. To release the device’s battery tray, press upward and then pull outward slightly with the thumb.
2. Remove the old batteries from the battery tray. Dispose of the batteries properly.
3. Insert two new 1.5-volt AAA-size batteries. Follow the polarity markings (+ and -) as illustrated in Figure B. Proper positioning of the batteries is essential for operation.
4. Carefully guide the battery tray back onto the device. Press downward and then push inward slightly to re-secure the battery tray (figure C). Do not force it into place; it fits only when properly positioned.
5. Insert your finger into the device to verify the operation. See the Activating the Onyx Vantage 9590 and Verifying Operation section for more information.

Activating the Onyx Vantage 9590 and Verifying Operation

The device contains numeric Light-Emitting Diodes (LEDs) that display oxygen saturation and pulse rate. A tricolour LED display (pulse quality indicator, shown at left) provides a visual indication of the pulse signal quality while blinking at the corresponding pulse rate. This display changes colours to alert you to changes in pulse quality that may affect the readings:

• Green indicates a good pulse signal.
• Yellow indicates a marginal pulse signal.
• Red indicates an inadequate pulse signal.

Activate the 9590 by inserting the patient’s finger into the device. The device detects the inserted finger and automatically illuminates the display. Correct positioning of the device on the finger is critical for accurate measurements.
NOTE: While on the finger, do not press the device against any surface and do not squeeze or hold it together. The internal spring provides the correct pressure; additional pressure may cause inaccurate readings.

1. Insert the patient’s finger, nail side up, into the 9590 until the fingertip touches the built-in stop guide.
2. Make sure the finger is lying flat (not on its side) and is centred within the device. For best results, keep the device at the patient’s heart or chest level.
3. If the device does not turn on, remove the finger and wait a few seconds before reinserting it. When a finger is inserted, the device performs a brief startup sequence. Verify that all LEDs illuminate during the startup sequence. If any LED is not lit, do not use the 9590; contact Nonin Technical Service for repair or replacement.
4. After the startup sequence, the device begins sensing the pulse (indicated by the blinking pulse quality indicator). Allow the device to stabilize and observe about 4 seconds of continuous green-coloured pulse quality before relying on the displayed values. Continually verify operation. It is common for the displayed values to fluctuate slightly over several seconds. If the pulse quality indicator blinks yellow or red, try another finger.
5. A minus sign (-) appears in the left-most digit of the %SpO2 display when the device senses the finger has been removed.
6. The last measured SpO2 and pulse rate values display for 10 seconds while the device automatically turns off.
7. The device will automatically shut off (to conserve battery life) approximately 10 seconds after the finger is removed or after 2 minutes of inadequate pulse signals.
8. If the 9590 does not turn on or if it shuts off unexpectedly:
   • Verify batteries are correctly inserted. Note: If batteries are installed backwards, the unit will not function.
   • The batteries are depleted. Replace batteries.
   • Continually verify operation. If the problem persists, remove the batteries and contact Nonin Technical Service.
   • The OxitestPlus7 by Datrend Systems, Inc. can be used to verify the operation of the pulse oximeter.

Using the Lanyard
WARNING: Certain activities may pose a risk of injury, including strangulation if the lanyard should become wrapped around your neck.
CAUTION : A flexible circuit connects the two halves. Do not twist or pull the flexible circuit or overextend the device’s spring. Do not hang the lanyard from the device’s flexible circuit. A lanyard is provided for convenience. The device will function with or without the lanyard. If lanyard use is desired, thread the lanyard as shown below.

Onyx Vantage 9590 Care, Maintenance, and Cleaning

The advanced digital circuitry within the device requires no calibration or periodic maintenance other than battery replacement. The device’s expected service life is 5 years. Field repair of the 9590 circuitry is not possible. Do not attempt to open the case or repair the electronics. Opening the case will damage the device and void the warranty. Do not open the 9590 more than 90°, and do not twist or pull on the device when cleaning.

Cleaning the Onyx Vantage 9590
CAUTIONS

• Clean the device before applying it to a patient.
• Do not sterilize, autoclave, or immerse this device in liquid. Do not pour or spray any liquids onto the device.
• Do not use caustic or abrasive cleaning agents, or any cleaning agent containing ammonium chloride or isopropyl alcohol.
• To clean, wipe the surfaces with a soft cloth dampened with a mild detergent or a 10% bleach solution or equivalent. (household bleach [5.25% sodium hypochlorite]).
• Do not use undiluted bleach or any cleaning solution other than those recommended here, as permanent damage could result.
• Dry with a soft cloth, or allow to air dry. Ensure that all surfaces are completely dry.

Equipment Response Time
If the signal from the sensor is inadequate, the last measured SpO2 and pulse rate values freeze for 10 seconds and are then replaced with dashes.

Example: SpO2 Exponential Averaging
SpO2 decreases 0.75% per second; pulse rate = 75 BPM
The response of the 4-beat average is 1.5 seconds.

Testing Summary
SpO2 accuracy and low perfusion testing were conducted by Nonin Medical, Inc. as described below.

SpO2 Accuracy Testing

At an independent research laboratory, SpO2 accuracy testing is conducted during induced hypoxia studies on healthy, male and female, non-smoking, light-to-dark-skinned subjects that are aged 18 years and older. The measured arterial hemoglobin saturation value (SpO2) of the device is compared to the arterial hemoglobin oxygen (SaO2) value, determined from blood samples with a laboratory co-oximeter. The accuracy of the device is in comparison to the co- oximeter samples measured over the SpO2 range of 70–100%. Accuracy data is calculated using the root-mean-squared (Arms value) for all subjects, per ISO 80601-2-61 and ISO 9919, Standard Specification for Pulse Oximeters for Accuracy.

Low Perfusion Testing
This test uses a SpO2 Simulator to provide a simulated pulse rate, with adjustable amplitude settings of various SpO2 levels. The device must maintain accuracy by ISO 80601-2-61 and ISO 9919 for pulse rate and SpO2 at the lowest obtainable pulse amplitude (0.3% modulation).

Performance in Motion
Motion artifact simulation introduced by a pulse oximeter tester determines whether the oximeter meets the criteria of ISO 80601-2-61 and ISO 9919 for pulse rate during simulated movement, tremor, and spike motions. Contact regulatory@nonin.com for more information regarding motion testing.

Principles of Operation
Pulse oximetry is a non-invasive method that passes red and infrared light through perfused tissue and detects the fluctuating signals caused by arterial pulses. Well-oxygenated blood is bright red, while poorly oxygenated blood is dark red. The pulse oximeter determines functional oxygen saturation of arterial hemoglobin (SpO2) from this colour difference by measuring the ratio of absorbed red and infrared light as volume fluctuates with each pulse.
