Safety Information, Warnings, and
Cautions
The following section lists warnings, cautions, notes, and safety information
for Pronto-7.
Pronto-7 is to be operated by qualified personnel only. The manual,
accessories, directions for use, all precautionary information, and
specifications should be read before use.
Pronto-7 Safety Information, Warnings, and Cautions
www.masimo.com 10 Masimo
Safety Information, Warnings, and Cautions
Always use the Pronto-7 precisely in accordance with the directions in
this manual, including finger selection, finger alignment in the sensor,
and subject behavior during testing. Failure to follow all of the
directions in this manual could lead to inaccurate measurements.
The Pronto-7 should be considered an early warning device. Blood
samples should be analyzed by laboratory instruments prior to clinical
decision making to completely understand the patient’s condition.
Variation in hemoglobin measurements may be profound and may be
affected by sample type, body positioning, as well as other
physiological conditions. As with most hemoglobin tests, Pronto-7 test
results should be scrutinized in light of a specific patient’s condition.
Any results exhibiting inconsistency with the patient’s clinical status
should be repeated and/or supplemented with additional test data.
Pulse rate measurement is based on the optical detection of a peripheral flow
pulse and therefore may not detect certain arrhythmias. The Pronto-7 should
not be used as a replacement or substitute for ECG based arrhythmia
analysis.
If SpO2 values indicate hypoxemia, a laboratory blood sample should be taken
to confirm the patient’s condition.
SpO2 is empirically calibrated in healthy adult volunteers with normal levels of
carboxyhemoglobin (COHb) and methemoglobin (MetHb).
Inaccurate SpO2 readings may be caused by:
• Elevated levels of COHb or MetHb: High levels of COHb or MetHb
may occur with a seemingly normal SpO2. When elevated levels of
COHb or 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
• Severe anemia
• Low arterial perfusion
• Motion artifact
Inaccurate SpHb readings may be caused by:
• Improper sensor application
• Intravascular dyes such as indocyanine green or methylene blue

Chapter 1: Technology Overview
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.
rainbow Pulse CO-Oximetry Technology
Pulse CO-Oximetry is governed by the following principles:
1. Oxyhemoglobin (oxygenated blood), deoxyhemoglobin
(non-oxygenated blood), carboxyhemoglobin (blood with carbon
monoxide content), methemoglobin (blood with oxidized
hemoglobin) and blood plasma constituents differ in their absorption
of visible and infrared light (using spectrophotometry, see figure
below).
Pronto-7 Chapter 1: Technology Overview
www.masimo.com 16 Masimo
2. The amount of arterial blood in tissue changes with a person’s pulse
(photoplethysmography). Therefore, the amount of light absorbed by
the varying quantities of blood changes as well.
The Pronto-7 uses a multi-wavelength sensor to distinguish between
oxygenated blood, deoxygenated blood and blood plasma. The Pronto-7
utilizes a sensor with various light-emitting diodes (LEDs) that pass light
through the site to multiple photodiodes (detectors). See the figure below.
Light-
Emitting Diodes (LEDs)
(7+ Wavelengths)
Detectors
Signal data is obtained by passing various visible and infrared lights (ranging
from 500nm up to 1300nm) through a capillary bed (for example, a fingertip)
and measuring changes in light absorption during the blood pulsatile cycle.
This information may be useful to clinicians. The maximum radiant power of
the strongest light is rated at ≤ 25mW. The detectors receive the light, convert
it into an electronic signal and send it to the Pronto-7 for calculation.
Once the Pronto-7 receives the signal from the sensor, it utilizes proprietary
algorithms to calculate the patient's functional oxygen saturation (%SpO2),
total hemoglobin concentration (SpHb [g/dL]) and pulse rate (BPM). The
SpHb measurement relies on a multiwavelength calibration equation to
estimate the percentage of total hemoglobin in blood. In an ambient
temperature of 95º F (35º C) the maximum skin surface temperature has been
measured at less than 106º F (41º C), verified by Masimo sensor skin
temperature test procedure.
Functional Oxygen Saturation
The Pronto-7 is calibrated to measure and display functional oxygen
saturation (SpO2): the amount of oxyhemoglobin expressed as a percentage
of the hemoglobin that is available to transport oxygen. Refer to the Safety
information, Warnings and Cautions section in front of this manual for details.
Pronto-7 vs. Drawn Whole Blood Measurements
When SpO2 and SpHb measurements obtained from the instrument
(noninvasive) are compared to drawn whole blood measurements (invasive)
Pronto-7 Chapter 1: Technology Overview
www.masimo.com 17 Masimo
by blood gas and/or laboratory hematology, caution should be taken when
evaluating and interpreting the results. The blood gas and/or laboratory
hematology measurements may differ from the SpO2 and SpHb
measurements of the Pronto-7.
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.
High levels of bilirubin may cause erroneous SpO2 and SpHb readings. 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, carboxyhemoglobin and mehemoglobin concentration of
the patient are stable and not changing over the period of time that the blood
gas sample is taken. Subsequently, blood gas and laboratory hematology
measurements of SpO2 and SpHb may 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.

Parameter and Measurement Descriptions
Total Hemoglobin (SpHb)
Pulse CO-Oximetry is a continuous and noninvasive method of measuring the
levels of total hemoglobin (SpHb) in arterial blood. It relies on the same
principles of pulse oximetry to make its SpHb measurement. The
measurement is taken by a sensor capable of measuring SpHb, usually on the
fingertip for adult and pediatric patients.
The sensor connects directly to the Pulse CO-Oximeter or with a patient
cable. The sensor collects signal data from the patient and sends it to the
instrument. The instrument displays the calculated data as measurement of
total hemoglobin concentration.
Pronto-7 Chapter 2: Product Description
www.masimo.com 24 Masimo
Arterial Oxygen Saturation (SpO2)
Pulse oximetry is a noninvasive method of measuring the level of functional
arterial oxygen saturation in blood. The instrument displays the calculated
data as a percent value for functional arterial oxygen saturation (SpO2).
A SpO2 reading is associated with correct sensor placement, small
physiological changes during the measurement and acceptable levels of
arterial perfusion at the measurement site.
Pulse Rate (PR)
Pulse rate (PR), measured in beats per minute (BPM) is based on the optical
detection of peripheral flow pulse.
Perfusion Index (PI)
The Perfusion Index (PI) is the ratio of the pulsatile blood flow to the
non-pulsatile or static blood in peripheral tissue. PI thus represents a
noninvasive measure of peripheral perfusion that can be continuously and
noninvasively obtained from a pulse oximeter.
Hematocrit (SpHct)
Hematocrit (SpHct) is the fraction of whole blood volume that consists of red
blood cells. In normal conditions, there is a linear relationship between
hematocrit and the concentration of hemoglobin. An estimated hematocrit as
a percentage may be derived by multiplying the hemoglobin concentration in
g/ dL times three and dropping the units 1,2. The hematocrit measurement is
determined mathematically in the instrument as*:
%SpHct = 3.0422 x SpHb – 0.8059
The measurement is taken by a sensor capable of measuring SpHct, usually
on the fingertip for adults or pediatric patients. The sensor collects signal data
from the patient and sends it to the instrument. The instrument displays the
calculated data as measurement of SpHct. The hematocrit estimation is NOT
reliable in cases of abnormal blood composition and is not indicative of
disease states. Abnormal values of hematocrit that are displayed should
warrant repeat testing by conventional laboratory methods.
*Note: This is the relationship found between tHb and SpHb for 3,226 blood
samples measured on a Coulter LH 500 Hematology Analyzer.
