Product Description, Indications for Use, Contraindications, and Features The following chapter contains the Radical-7 product description, key features and benefits, indications for use, contraindications, and safety information, including cautions, warnings, and notes.
Product Description The Radical-7 is a noninvasive monitor that measures arterial oxygen saturation (SpO2), pulse rate, and perfusion index (PI), along with optional measurements of hemoglobin (SpHb), carboxyhemoglobin (SpCO), methemoglobin (SpMet), total oxygen content (SpOC), Pleth Variability Index (PVI), and Acoustic Respiration Rate (RRa). The Radical-7 can be used as either a Handheld or a Standalone monitor. The Radical-7 features a touchscreen Liquid Crystal Display (LCD) that continuously displays numeric values for all parameters. The Radical-7 provides graphical displays for plethysmographic waveform, respiratory waveform, Signal Identification and Quality Indicator (Signal IQ). The Radical-7 can also be used to interface with a multi-parameter patient monitor to send Masimo SET pulse oximetry information to that monitor for display. The Radical-7 has an embedded 802.11 wireless radio that can be used for connectivity.
Key Features The following features are available for the Radical-7. Some features are optional:
Masimo SET is clinically proven to satisfy all sensitivity and specificity requirements for pulse oximeter technology.
Rainbow technology uses 7+ wavelengths of light to continuously and noninvasively measure carboxyhemoglobin (SpCO), methemoglobin (SpMet), and total hemoglobin (SpHb), as well as providing a more reliable probe-off detection.
Total oxygen content (SpOC) provides a calculated measurement of the amount of oxygen in arterial blood, which may provide useful information about oxygen both dissolved in plasma and combined with hemoglobin.
Perfusion Index (PI) with trending capability indicates arterial pulse signal strength and may be used as a diagnostic tool during low perfusion.
Pleth Variability Index (PVI) may show changes that reflect physiologic factors such as vascular tone, circulating blood volume, and intrathoracic pressure excursions. [The utility of PVI is unknown at this time and requires further clinical studies. Technical factors that may affect PVI include probe malposition and patient motion.]
Respiration rate can be determined by the acoustic (RRa) or plethysmographic waveform (RRp).

Radical-7
Safety Information, Warnings, and Cautions Warning The Radical-7 cannot measure elevated levels of COHb or MetHb. Warning Inaccurate SpO2 readings may be caused by:
Elevated levels of COHb and MetHb
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.
For increased MetHb: the SpO2 may be decreased by levels of MetHb of up to approximately 10% to 15%. At higher levels of MetHb, the SpO2 may tend to read in the low to mid 80s. When elevated levels of MetHb are suspected, laboratory analysis (CO-Oximetry) of a blood sample should be performed.
Intravascular dyes such as indocyanine green or methylene blue
Externally applied coloring and texture such as nail polish, acrylic nails, glitter, etc.
Elevated levels of bilirubin

Masimo
Radical-7
Safety Information, Warnings, and Cautions Warning Always remove the sensor from the patient and completely disconnect the patient from the Radical-7 before bathing the patient. Caution If using the Radical-7 during full body irradiation, keep the sensor out of the radiation field. If the sensor is exposed to the radiation, the reading might be inaccurate or the instrument might read zero for the duration of the active irradiation period.
Do not loop the sensor cable into a tight coil or wrap around the device, as this can damage the sensor cable. Patient Safety - If a sensor is damaged in any way, discontinue use immediately. Failure to apply the sensor properly may lead to incorrect measurements. Additional information specific to the Masimo sensors compatible with Radical-7, including information about parameter/measurement performance during motion and low perfusion, may be found in the sensor's directions for use (DFU). Do not expose the Masimo sensors used with Radical-7 to moisture, liquids or a humid environment, as this may make the sensor perform inaccurately or fail. High-intensity extreme lights (including pulsating strobe lights and direct sunlight) directed on the sensor, may not allow the Radical-7 to obtain readings. When using the Maximum Sensitivity setting, performance of the Sensor Off detection may be compromised. If the Radical-7 is in this setting and the sensor becomes dislodged from the patient, the potential for false readings may occur due to environmental "noise" such as light, vibration, and excessive air movement.

Chapter 1: Technology Overview The following chapter contains general descriptions about parameters, measurements, and the technology used by Masimo products.
Signal Extraction Technology (SET) Masimo Signal Extraction Technology's signal processing differs from that of 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®), in parallel with Fast Saturation Transform (FST®), 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.
