Pulse
Quality
Indicator
The device contains numeric Light-Emitting Diodes (LEDs) that display oxygen
saturation and pulse rate. A tricolor 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 colors 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 9550 by inserting the patient’s finger into the device. The device detects
the inserted finger and automatically illuminates the displays. 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 9550 until the fingertip touches the
built-in stop guide.
2. Make sure the finger is lying flat (not on its side) and is centered within the device. For
best results, keep the 9550 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 9550;
contact Nonin Customer Support for repair or replacement. 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-colored
pulse quality before relying on the displayed values. It is common for the displayed
values to fluctuate slightly over a period of several seconds. If the pulse quality
indicator blinks yellow or red, try another finger.
A minus sign (-) appears in the left-most digit of the %SpO2 display when the device
senses the finger has been removed. The last measured SpO2 and pulse rate values
display for 10 seconds while the device automatically turns off. The device will
automatically shut off (to conserve battery life) approximately 10 seconds after the
finger is removed, or after a 2-minute period of inadequate pulse signals.

Testing Summary
Refer to the following tables for specific information regarding this device’s compliance to IEC 60601-1-2.
SpO2 accuracy and low perfusion testing was conducted by Nonin Medical, Incorporated as described
below.
Table 1: Electromagnetic Emissions
Emissions Test
SpO2 Accuracy Testing
SpO2 accuracy testing is conducted during induced hypoxia studies on healthy, non-smoking, light-to-darkskinned subjects in an independent research laboratory. The measured arterial hemoglobin saturation value
(SpO2) of the device is compared to 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-meansquared (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 an SpO2 Simulator to provide a simulated pulse rate, with adjustable amplitude settings of
various SpO2 levels. The device must maintain accuracy in accordance with ISO 80601-2-61 and ISO 9919
for pulse rate and SpO2 at the lowest obtainable pulse amplitude (0.3% modulation).
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 color difference by measuring the ratio of absorbed red and infrared light as
volume fluctuates with each pulse.
