Safety Information, Warnings, and Cautions
CAUTION: The device must be configured to match your local power line frequency to allow for the cancelation of noise introduced by fluorescent lights and other sources. CAUTION: If the Low SIQ Indicator illuminates frequently, find a better perfused monitoring site. In the interim, assess the patient and, if indicated, verify oxygenation status through other means. CAUTION: If using pulse oximetry 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 device might read zero for the duration of the active irradiation period. CAUTION: When patients are undergoing photodynamic therapy they may be sensitive to light sources. Pulse oximetry may be used only under careful clinical supervision for short time periods to minimize interference with photodynamic therapy. CAUTION: If SpO2 values indicate hypoxemia, a laboratory blood sample should be taken to confirm the patient’s condition. Note: A functional tester cannot be used to assess the accuracy of the Pronto. Note: It is recommended that Pronto battery is fully charged prior to use. Note: All batteries lose capacity with age, thus the amount of run time at Low Battery will vary depending upon the age of the battery. Note: Do not loop the patient cabling into a tight coil or wrap around the device, as this can damage the patient cabling. Note: Additional information specific to the Masimo sensors compatible with Pronto, including information about parameter/measurement performance during motion and low perfusion, may be found in the sensor's directions for use (DFU).

Chapter 1: Technology Overview The following chapter contains general descriptions for the parameters, measurements, and technology used within Masimo products.
Masimo Signal Extraction Technology (Masimo SET®) The signal processing in Masimo Signal Extraction Technology (Masimo SET®) 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 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.

Masimo SET® DST This figure is for conceptual purposes only.
General Description for Oxygen Saturation (SpO2) Pulse oximetry is governed by the following principles: 1. 2.
Oxyhemoglobin (oxygenated blood) and deoxyhemoglobin (non-oxygenated blood) differ in their absorption of red and infrared light (spectrophotometry). The amount of arterial blood in tissue changes with your pulse (photoplethysmography). Therefore, the amount of light absorbed by the varying quantities of arterial blood changes as well.
Functional Oxygen Saturation (SpO2) The Pronto 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. Note: Dyshemoglobins are not capable of transporting oxygen, but are recognized as oxygenated hemoglobins by conventional pulse oximetry.
General Description for Pulse Rate (PR) Pulse rate (PR), measured in beats per minute (bpm), is based on the optical detection of peripheral flow pulse.
General Description for 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.

rainbow Pulse CO-Oximetry Technology rainbow Pulse CO-Oximetry technology is governed by the following principles: 1.
2.
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). The amount of arterial blood in tissue changes with pulse (photoplethysmography). Therefore, the amount of light absorbed by the varying quantities of arterial blood changes as well.
Pronto uses a multi-wavelength sensor to distinguish between oxygenated blood, deoxygenated blood, blood with carbon monoxide, oxidized blood, and blood plasma. Pronto utilizes a sensor with various light-emitting diodes (LEDs) that pass light through the site to a diode (detector). Signal data is obtained by passing various visible and infrared lights (LEDs, 500 to 1400nm) through a capillary bed (for example, a fingertip, a hand, a foot) 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 ≤ 25 mW. The detector receives the light, converts it into an electronic signal, and sends it to Pronto for calculation. 1. 2.
Light Emitting Diodes (LEDs) (7 + wavelengths) Detector
Once the Pronto 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 (PR). The SpHb measurement relies on a multi-wavelength calibration equation to quantify the percentage of carbon monoxide and methemoglobin and the concentration of total hemoglobin in arterial blood. Maximum skin-sensor interface temperature was tested to be less than 41º C (106º F) in a minimum ambient temperature of 35º C (95º F). The tests were conducted with sensors operating at reasonable worst case power. www.masimo.com

Chapter 1: Technology Overview
Pulse CO-Oximetry vs. Drawn Whole Blood Measurements When SpO2 and SpHb measurements obtained from Pronto (noninvasive) are compared to drawn whole blood (invasive) measurements by blood gas and/or laboratory CO-Oximetry methods, caution should be taken when evaluating and interpreting the results. The blood gas and/or laboratory CO-Oximetry measurements may differ from the SpO2 and SpHb measurements of Pronto. Any comparisons should be simultaneous, meaning the measurement on the device should be noted at the exact time that blood is drawn. 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. In the case of SpHb, variation in hemoglobin measurements may be profound and may be affected by sampling technique as well as the patient's physiological conditions. Any results exhibiting inconsistency with the patient's clinical status should be repeated and/or supplemented with additional test data. As with most hemoglobin tests, a laboratory blood sample should be analyzed prior to clinical decision making. 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 methemoglobin 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 CO-Oximetry 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. Measurements with Low Signal IQ should not be compared to laboratory measurements.
General Description for 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 adults 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 device. The device displays the calculated data as measurement of total hemoglobin concentration.
Successful Monitoring for SpHb A stable SpHb reading is associated with correct sensor placement, small physiological changes during the measurement and acceptable levels of arterial perfusion at the measurement site. Physiological changes at the measurement site are mainly caused by fluctuations in the oxygen saturation, blood concentration, and perfusion. See Safety Information, Warnings, and Cautions on page 9.

Chapter 1: Technology Overview
SpO2 and SpHb Measurements During Patient Motion Pronto displays measurements of SpO2 and may display SpHb during patient motion. However, because of the changes in the physiological parameters such as blood volume, arterial-venous coupling, etc. that occur during patient motion, the accuracy of such measurements may not be reliable during excessive motion. In this case, the Low SIQ indicator illuminates to alert the clinician that the device does not have confidence in the value displayed due to poor signal strength caused by excessive motion or other signal interference.
