Pronto-7
Section 1 - Overview
Pulse CO-Oximeter The following chapter contains general descriptions about parameters, measurements, and the technology used by Masimo products.
General Description for Oxygen Saturation (SpO2) Pulse oximetry is a noninvasive method of measuring the level of functional arterial oxygen saturation in blood. The measurement is taken by placing a sensor (2) on a patient, usually on the finger for adults and pediatric patients. The sensor connects to the pulse oximetry device (1). The sensor collects signal data from the patient and sends it to the device. The device displays the calculated data as a percent value for functional arterial oxygen saturation (SpO2).
Functional Oxygen Saturation The Pronto-7 is calibrated to measure and display functional arterial 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.
General Description for Total Hemoglobin (SpHb) Pulse CO-Oximetry devices offer a noninvasive method of measuring the levels of total hemoglobin in blood (SpHb). It relies on pulse oximetry principles to make SpHb measurements. The device displays the data as grams/deciliter (g/dL) for SpHb (with different units of measure available in the display menu).
Pulse Rate (PR) Pulse rate (PR), measured in beats per minute (bpm) is based on the optical detection of peripheral flow pulse.

Section 1 - Overview
Perfusion Index 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 noninvasively obtained from a pulse oximeter.
Principles of Operation 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
Section 1 - Overview
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. 1. 2.
Light Emitting Diodes (LEDs) (7 + wavelengths) Detector
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 arterial oxygen saturation (%SpO2), total hemoglobin concentration (SpHb [g/dL]) and pulse rate (bpm). The SpHb measurement relies on a multi-wavelength calibration equation to estimate the total hemoglobin concentration in the blood. The maximum skin surface temperature is measured to be less than 106º F (41º C) in a minimum 95º F (35º C) ambient. This is verified by Masimo sensor skin temperature test procedures.

Section 1 - Overview
Pronto-7 vs. Drawn Whole Blood Measurements It is important to recognize all measuring devices and processes have an inherent level of variability. SpO2 and SpHb measurements obtained from the device (noninvasive) when compared to drawn whole blood measurements (invasive) by blood gas and/or automated laboratory hematology analyzer may differ. There are a variety of factors that may significantly impact the difference. For noninvasive SpO2 and SpHb measurements, the factors are described as part of the Safety Information, Warnings and Cautions. For invasive blood test, error and/or variability may occur at three separate phases1-4: •
Pre-analytical - patient preparation, sample collection, transportation, storage, and processing before analysis.
•
Analytical - sample analysis.
•
Post-analytical - report generation, delivery and interpretation.
Each phase is susceptible to some level of error and/or variability that can impact the accuracy and precision of the measurement. Some of the most common sources of variability in invasive measurements are: •
Sample Integrity - sample type (arterial, venous, or capillary), collection technique, timing between measurements, tourniquet release time.
•
Physiological - body position, homeostasis, hydration, blood source, and site of blood draw.
•
Biological – gender, age, ethnicity, and rhythms (circadian).
