SAFETY INFORMATION, WARNINGS, CAUTIONS AND NOTES
The Rad-8 Pulse Oximeter is designed to minimize the possibility of hazards from errors in the software
program by following sound engineering design processes, Risk Analysis and Software Validation.
■Explosion hazard. Do not use the Rad-8 in the presence of flammable anesthetics or other flammable
substance in combination with air, oxygen-enriched environments, or nitrous oxide.
■High intensity extreme lights (including pulsating strobe lights) directed on the sensor, may not allow
the Pulse Oximeter to obtain readings.
■The Rad-8 is NOT intended for use as an apnea monitor.
■The Pulse Oximeter should be considered an early warning device. As a trend towards patient
hypoxemia is indicated, blood samples should be analyzed by laboratory instruments to completely
understand the patient’s condition.
■Pulse rate measurement is based on the optical detection of a peripheral flow pulse and therefore
may not detect certain arrhythmias. The pulse oximeter should not be used as a replacement or
substitute for ECG based arrhythmia analysis.
■The Rad-8 is to be operated by qualified personnel only. This manual, accessory directions for use, all
precautionary information, and specifications should be read before use.
■Electric shock hazard. Do not open the Rad-8 device. Only a qualified operator may perform
maintenance procedures specifically described in this manual. Refer servicing to Masimo for repair of
this equipment.
■As with all medical equipment, carefully route patient cabling to reduce the possibility of patient
entanglement or strangulation.
■Do not place the Rad-8 or accessories in any position that might cause it to fall on the patient. Do not
lift the Rad-8 by the power cord or any other cable.
■Interfering Substances: Dyes, or any substance containing dyes, that change usual blood pigmentation
may cause erroneous readings.
■SpO2is empirically calibrated to functional arterial oxygen saturation in healthy adult volunteers with
normal levels of carboxyhemoglobin (COHb) and methemoglobin (MetHb). A pulse oximeter can
not measure elevated levels of COHb or MetHb. Increases in either COHb or MetHb will affect the
accuracy of the SpO2measurement.
■For increased COHb: COHb levels above normal tend to increase the level of SpO2. The level of
increase is approximately equal to the amount of COHb that is present.
NOTE: High levels of COHb may occur with a seemingly normal SpO2.When elevated levels of COHb
are suspected, laboratory analysis (co-oximetry) of a blood sample should be performed.
■Elevated levels of Methemoglobin (MetHb) will lead to inaccurate SpO2measurements. When
elevated levels of MetHb are suspected, laboratory analysis (co-oximetry) of a blood sample should
be performed.
■Elevated levels of Carboxyhemoglobin (COHb) will lead to inaccurate SpO2measurements. When elevated
levels of COHb are suspected, laboratory analysis (co-oximetry) of a blood sample should be
performed.
■Elevated levels of Total Bilirubin may lead to inaccurate SpO2measurements.
■Severe anemia may cause erroneous SpO2readings.
■Do not use the Rad-8 or sensors during magnetic resonance imaging (MRI) scanning. Induced current
could potentially cause burns.The Rad-8 may affect the MRI image and the MRI device may affect the
accuracy of the Pulse Oximetry parameters and measurements.

SAFETY INFORMATION, WARNINGS, CAUTIONS AND NOTES
■If using Rad-8 during full body radiation, keep the sensor out of the radiation field. If the sensor is
exposed to the radiation, the reading might be inaccurate or the device might read zero for the duration
of the active irradiation period.
■For home use, ensure that the Rad-8 alarm can be heard from other rooms in the house especially
when noisy appliances such as vacuum cleaners, dishwashers, clothes dryers, televisions, or radios
are operating.
■Always remove the sensor from the patient and completely disconnect the patient from the Rad-8
before bathing the patient.
■Additional information specific to Masimo sensors including information about parameter/measurement
performance during motion and low perfusion, may be found in the sensor's Directions For Use (DFU).
■Do not place the Rad-8 where the controls can be changed by the patient.
■Do not place the Rad-8 face against a surface. This will cause the alarm to be muffled.
■Do not place the Rad-8 on electrical equipment that may affect the Pulse Oximeter, preventing it from
working properly.
■Do not expose the Rad-8 to excessive moisture such as direct exposure to rain. Excessive moisture
can cause the device to perform inaccurately or fail.
■Do not place containers with liquids on or near the Rad-8. Liquids spilled on the device may cause it
to perform inaccurately or fail.
■If the Rad-8 fails any part of the setup procedures or leakage tests, remove the device from operation
until qualified service personnel have corrected the situation.
■If a sensor is damaged in any way, discontinue use immediately.
■Disposal of product - Comply with local laws in the disposal of the device and/or its accessories.
■The Rad-8 can be used during defibrillation, but the readings may be inaccurate for up to 20
seconds.

Pulse Oximetry
SpO2GENERAL DESCRIPTION
Pulse Oximetry is a continuous and noninvasive method of measuring the level of
arterial oxygen saturation in blood. The measurement is taken by placing a sensor on a
patient, usually on the fingertip for adults and the hand or foot for neonates. The sensor
is connected to the Pulse Oximetry instrument with a patient cable. The sensor collects
signal data from the patient and sends it to the instrument. The following figure shows
the general monitoring setup.

3. Sensor
PRINCIPLE OF OPERATION
Pulse Oximetry is governed by the following principles:
1. Oxyhemoglobin (oxygenated blood) and deoxyhemoglobin (non-oxygenated
blood) constituents differ in their absorption of visible and infrared light (using
spectrophotometry, see figure below).

2. The amount of arterial blood in tissue changes with your pulse (photoplethysmography).
Therefore, the amount of light absorbed by the varying quantities of arterial blood
changes as well.

Rad-8 Signal Extraction Pulse Oximeter Operator’s Manual 1-5

overview
PRINCIPLE OF OPERATION (CONTINUED)
The Rad-8 Pulse Oximeter uses a two-wavelength pulsatile system to distinguish between
oxygenated and deoxygenated blood. Signal data is obtained by passing red (rd) (660 nm
wavelength) and infrared (ir) (905 nm wavelength) light through a capillary bed (for example
a fingertip, a hand or a foot) and measuring changes in light absorption during the pulsatile
cycle. This information may be useful to clinicians. The radiant power of the light is rated at
0.79mW (max.). See figure below. The Rad-8 utilizes a sensor with red and infrared light-
emitting diodes (LEDs) that pass light through the site to a photodiode (photodetector).
The photodetector receives the light, converts it into an electronic signal and sends it to
the Rad-8 for calculation.
Once the device receives the signal from the sensor, it utilizes Masimo SET signal
extraction technology for calculation of the patient’s functional oxygen saturation
and pulse rate. The maximum of the skin surface temperature is measured at an
ambient temperature of less than 106º F (41º C). This is verified by Masimo sensor
skin temperature test procedures.
FUNCTIONAL SATURATION
The Rad-8 is calibrated to measure and display functional saturation (SpO2): the amount
of oxyhemoglobin expressed as a percentage of the hemoglobin that is available to
transport oxygen.
RAD-8 VS. DRAWN WHOLE BLOOD MEASUREMENTS
When SpO2measurements obtained from the Rad-8 (noninvasive) are compared to drawn
whole blood (invasive) measurements by blood gas and/or laboratory oximetry methods, caution
should be taken when evaluating and interpreting the results. The blood gas and/or laboratory-
oximetry measurements may differ from the SpO2measurements of the Rad-8 Pulse Oximeter.
In the case of SpO2, different results are usually obtained from the arterial blood gas sample
if the calculated measurement is not appropriately corrected for the effects of variables that
shift the relationship between the partial pressure of oxygen (PO2) and saturation, such as: pH,
temperature, the partial pressure of carbon dioxide (PCO2), 2,3-DPG, and fetal hemoglobin. As
blood samples are usually taken over a period of 20 seconds (the time it takes to draw the blood)
a meaningful comparison can only be achieved if the oxygen saturation of the patient is stable
and not changing over the period of time that the blood gas sample is taken. Subsequently, blood
gas and laboratory oximetry measurements of SpO2may vary with the rapid administration of
fluids and in procedures such as dialysis. Additionally, drawn, whole-blood testing can be affected
by sample handling methods and time elapsed between blood draw and sample testing.

SIGNAL EXTRACTION TECHNOLOGY (SET) FOR SpO2MEASUREMENTS
Masimo Signal Extraction Technology’s signal processing differs from conventional pulse
oximeters. Conventional pulse oximeters assume that arterial blood is the only blood moving
(pulsating) in the measurement site. During patient motion, however, the venous blood also
moves, causing conventional pulse oximeters to read low values, because they cannot distinguish
between the arterial and venous blood movement (sometimes referred to as noise). Masimo SET
pulse oximetry utilizes parallel engines and adaptive digital filtering. Adaptive filters are powerful
because they are able to adapt to the varying physiologic signals and/or noise and separate them
by looking at the whole signal and breaking it down to its fundamental components.The Masimo
SET signal processing algorithm, Discrete Saturation Transform®(DST®) reliably identifies the
noise, isolates it and, using adaptive filters, cancels it. It then reports the true arterial oxygen
saturation for display on the monitor.
FASTSAT
FastSat enables rapid tracking of arterial oxygen saturation changes. Arterial oxygen
saturation data is averaged using pulse oximeter averaging algorithms to smooth the trend.
When the Rad-8 is set to FastSat “On”, the averaging algorithm evaluates all the saturation
values providing an averaged saturation value that is a better representation of the patient’s
current oxygenation status. With FastSat, the averaging time is dependent on the input
signal.
