Overview
INDICATIONS FOR USE
The Radical-7R Pulse CO-Oximeter and accessories are indicated for the continuous
noninvasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2),
pulse rate, carboxyhemoglobin saturation (SpCO), methemoglobin saturation (SpMet), total
hemoglobin concentration (SpHb), and/or respiratory rate (RRa). The Radical-7R Pulse CO-
Oximeter and accessories are indicated for use with adult, pediatric, and neonatal patients
during both no motion and motion conditions, and for patients who are well or poorly perfused
in hospitals, hospital-type facilities, mobile, and home environments. In addition, the Radical-
7R Pulse CO-Oximeter and accessories are indicated to provide the continuous noninvasive
monitoring data obtained from the Radical-7R Pulse CO-Oximeter and accessories of
functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate to multi-parameter
devices for the display of those devices.

GENERAL DESCRIPTION
Pulse CO-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 fi ngertip for adults and the hand or foot for neonates. The sensor is connected to the Pulse
CO-Oximetry instrument with a patient cable. The sensor collects signal data from the patient
and sends it to the instrument. The instrument displays the calculated data in three ways:
1. As a percent value for arterial oxygen saturation (SpO
2
)
2. As a pulse rate (PR)
3. As a plethysmographic waveform

SpCO GENERAL DESCRIPTION
Pulse CO-Oximetry is a continuous and noninvasive method of measuring the levels of carbon
monoxide concentration (SpCO) in arterial blood. It relies on the same basic principles of pulse
oximetry (spectrophotometry) to make its SpCO measurement. The measurement is obtained
by placing a sensor on a patient, usually on the fi ngertip for adults and the hand or foot for
infants. The sensor connects either directly to the Pulse CO-Oximetry instrument or through a
patient cable. The sensor collects signal data from the patient and sends it to the instrument.
The instrument displays the calculated data as percentage value for the SpCO, which refl ect
blood levels of carbon monoxide bound to hemoglobin.
SpMet GENERAL DESCRIPTION
Pulse CO-Oximetry is a continuous and noninvasive method of measuring the levels of
methemoglobin concentration (SpMet) in arterial blood. It relies on the same basic principles
