Pulse oximetry and pulse rate
Portrait TM Wearable Pulse Oximetry Sensor
(Portrait SpO2 P-W01, Portrait SpO2 P-SE01)
intended use
The Portrait TM Wearable Pulse Oximetry Sensor (Portrait SpO2 P-SE01, Portrait SpO2
P-W01) is intended for use with adult and pediatric patients (3 years of age and older,
and weighing more than 10 kg) for continuous physiologic monitoring of oxygen
saturation (SpO
2
) and pulse rate (PR) parameters. The Wearable Pulse Oximetry Sensor
acquires parameter data from the patient and transmit it to the sensor battery for
communication to a host device through the Medical Body Area Network (MBAN)
connection.
The Portrait TM Wearable Pulse Oximetry Sensor is intended for use under the direct
supervision of a licensed practitioner, or by personnel trained in proper use of the
equipment in a professional healthcare facility.
The Portrait TM Wearable Pulse Oximetry Sensor is not intended for use in a controlled
Magnetic Resonance (MR) environment.
SpO
2
and pulse rate measurement limitations
●
Pulse oximetry and pulse rate measurements are intended for patients over three
years old and weighing ≥10 kg (22 lb).
●
Poor perfusion may affect the accuracy of the measurement.
●
Movement artifact may affect the accuracy of the measurement.
●
Ambient light conditions (such as surgical lights, especially xenon light sources;
fluorescent lights; direct sunlight; dimmable LED lights; patient’s mobile device in
the same hand) may interfere with the measurement accuracy.
●
To avoid erroneous measurement data, do not use a blood pressure cuff on the
same arm as the SpO
2
sensor.
●
The Hub must be kept in the proximity of the Wearable SpO
2
Parameter to enable
reliable MBAN connection.
●
The pulse oximeter may not reflect true arterial blood oxygen saturation when
dyshemoglobin levels are elevated.
●
You can only use one SpO
2
measurement on a patient at a time (one Wearable
SpO
2
Parameter with one Hub).
SpO
2
measurement description
Pulse oximetry (SpO
2
) is a non-invasive method used for monitoring tissue oxygenation.
The measurement method is based on the absorption of red and infrared light in
pulsating arterial blood. The ratio of oxygen carrying hemoglobin (HbO
2
) to the total
amount of hemoglobin capable of transporting oxygen (HbO
2
+ Hb) is called functional
oxygen saturation of arterial blood (SaO
2
). GE pulse oximetry is calibrated to display
functional oxygen saturation.
The actual measurement of arterial oxygen saturation is done by spectrophotometry,
a technique that quantifies the amount of transmitted light. A beam of light is
passed through a monitored site of pulsating arterial blood. A pulse oximeter emits
red and infrared light through its LEDs and measures the relative absorbtion of red
and infrared light. Because HbO
2
and Hb absorb different amounts of light at each
