Radical-7 Signal Extraction Pulse CO-Oximeter Operator’s Manual 1-3

Overview

Product Description

The Radical-7 Pulse CO-Oximeter is a noninvasive, arterial oxygen saturation, total hemoglobin

concentration and pulse rate monitor. The Radical-7 Pulse CO-Oximeter can be used as either

a Handheld or a Standalone monitor. The Radical-7 Pulse CO-Oximeter features a backlit

Liquid Crystal Display (LCD) that continuously displays numeric values for SpO

, SpMet

SpCO

*, SpHb

, SpOC™*, pulse rate, Perfusion Index (PI) and Pleth Variability Index (PVI).

It also provides graphical displays for plethysmographic waveform, Signal Identiﬁ cation and

Quality Indicator (Signal IQ

). The Radical-7 Pulse CO-Oximeter can be used to interface with

a multiparameter patient monitor to provide Masimo SET SpO

and pulse rate

information to

that monitor for display.

FEATURES

These features are common to the Radical-7 family:

■ Masimo SET is clinically proven to be the highest sensitivity and speciﬁ city pulse

oximeter technology in the world.

■ 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 reﬂ ect physiologic factors such as

vascular tone, circulating blood volume, and intrathoracic pressure excursions.

■ Accurate on cyanotic infants with congenital heart disease when used with an LNOP

Blue Sensor.

■ Signal IQ

waveform for signal identiﬁ cation and quality indication during excessive

motion and low signal to noise situations.

■

FastSat

tracks rapid changes in arterial O

with high ﬁ delity unlike any other pulse oximeter.

■ Variable pitch provides tonal variance for every 1% change in saturation.

■

SatShare

interface allows transfer of SpO

and pulse rate to an existing multiparameter monitor

and allows for the reading of SpCO, SpMet, SpHb and SpOC

on the Radical-7 monitor.

■

Automatic screen rotation provides upright display for vertical or horizontal monitor positioning.

■ Remote alarming interface.

■ Trend Auto Scale feature.

■ Detachable portable handheld for patient transport.

■ *3D ALARM™

■ Desat Index Alarm™ enables clinicians to detect an increasing quantity of smaller

desaturations that may precede declining respiratory status.

■ PI Delta Alarm™ alerts clinicians to possible changes in perfusion, often a reliable

indicator of illness severity.

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.
