SAFETY INFORMATION, WARNINGS, CAUTIONS AND NOTES
The Rad-87 Pulse CO-Oximeter is designed to minimize the possibility of hazards from errors in the software program by following sound engineering design processes, Risk Analysis and Software Validation. ■ Explosion hazard. Do not use the Rad-87 in the presence of flammable anesthetics or other flammable substance in combination with air, oxygen-enriched environments, or nitrous oxide. ■ ■ ■ ■ ■ ■ ■ ■ ■ ■
■ ■ ■ ii
High intensity extreme lights (including pulsating strobe lights) directed on the sensor, may not allow the Pulse CO-Oximeter to obtain readings. The Rad-87 is NOT intended for use as an apnea monitor. The Pulse CO-Oximeter should be considered an early warning device. As a trend towards patient hypoxemia is indicated, blood samples should be analyzed by laboratory instruments to completely understand the patient’s condition. Pulse rate measurement is based on the optical detection of a peripheral flow pulse and therefore may not detect certain arrhythmias. The pulse oximeter should not be used as a replacement or substitute for ECG based arrhythmia analysis. The Rad-87 is to be operated by qualified personnel only. This manual, accessory directions for use, all precautionary information, and specifications should be read before use. Electric shock hazard. Do not open the Rad-87 device. Only a qualified operator may perform maintenance procedures specifically described in this manual. Refer servicing to Masimo for repair of this equipment. As with all medical equipment, carefully route patient cabling to reduce the possibility of patient entanglement or strangulation. Do not place the Rad-87 or accessories in any position that might cause it to fall on the patient. Do not lift the Rad-87 by the power cord or any other cable. Interfering Substances: Dyes, or any substance containing dyes, that change usual blood pigmentation may cause erroneous readings. SpO2 is empirically calibrated to functional arterial oxygen saturation in healthy adult volunteers with normal levels of carboxyhemoglobin (COHb) and methemoglobin (MetHb). A pulse oximeter can not measure elevated levels of COHb or MetHb. Increases in either COHb or MetHb will affect the accuracy of the SpO2 measurement. ■ For increased COHb: COHb levels above normal tend to increase the level of SpO2. The level of increase is approximately equal to the amount of COHb that is present. NOTE: High levels of COHb may occur with a seemingly normal SpO2. When elevated levels of COHb are suspected, laboratory analysis (CO-Oximetry) of a blood sample should be performed. ■ For increased MetHb: the SpO2 may be decreased by levels of MetHb of up to approximately 10% to 15%. At higher levels of MetHb, the SpO2 may tend to read in the low to mid 80s. When elevated levels of MetHb are suspected, laboratory analysis (CO-Oximetry) of a blood sample should be performed. Elevated levels of Methemoglobin (MetHb) will lead to inaccurate SpO2 and SpCO measurements. Elevated levels of Carboxyhemoglobin (COHb) will lead to inaccurate SpO2 measurements. Elevated levels of Total Bilirubin may lead to inaccurate SpO2, SpMet and SpCO measurements. Rad-87 Pulse CO-Oximeter Operator’s Manual

Motion artifact may lead to inaccurate SpMet and SpCO measurements. Very low arterial Oxygen Saturation (SpO2) levels may cause inaccurate SpCO and SpMet measurements. Severe anemia may cause erroneous SpO2 readings. Do not use the Rad-87 or sensors during magnetic resonance imaging (MRI) scanning. Induced current could potentially cause burns. The Rad-87 may affect the MRI image and the MRI device may affect the accuracy of the Pulse CO-Oximetry parameters and measurements. If using Rad-87 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 radiation period. For home use, ensure that the Rad-87’s alarm can be heard from other rooms in the house especially when noisy appliances such as vacuum cleaners, dishwashers, clothes dryers, televisions, or radios are operating. Always remove the sensor from the patient and completely disconnect the patient from the Rad-87 before bathing the patient. Additional information specific to Masimo sensors including information about parameter/measurement performance during motion and low perfusion, may be found in the sensor's Directions For Use (DFU). Do not place the Rad-87 where the controls can be changed by the patient. Do not place the Rad-87's face against a surface. This will cause the alarm to be muffled. Do not place the Rad-87 on electrical equipment that may affect the Pulse CO-Oximeter, preventing it from working properly. Do not expose the Rad-87 to excessive moisture such as direct exposure to rain. Excessive moisture can cause the device to perform inaccurately or fail. Do not place containers with liquids on or near the Rad-87. Liquids spilled on the device may cause it to perform inaccurately or fail. Failure of Operation - If the Rad-87 fails any part of the setup procedures or leakage tests, remove the device from operation until qualified service personnel have corrected the situation. Patient Safety - If a sensor is damaged in any way, discontinue use immediately. Disposal of product - Comply with local laws in the disposal of the device and/or its accessories. The Rad-87 can be used during defibrillation, but the readings may be inaccurate for up to 20 seconds. This equipment has been tested and found to comply with the limits for medical devices to the EN 60601-1-2: 2002, Medical Device Directive 93/42/EEC and Class B digital device, Part 15, FCC Rules/USA.

INDICATIONS FOR USE The Rad-87 Pulse CO-Oximeter and accessories are indicated for the continuous, noninvasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2), carboxyhemoglobin and methemoglobin concentration expressed in percentage (SpCO and SpMet) and pulse rate (measured by an SpO2 sensor). The Rad-87 Pulse CO-Oximeter and accessories are indicated for use with adult, pediatric and neonatal patients during both motion and no motion conditions, who are well or poorly perfused patients in hospitals, hospital-type facilities, mobile and home environments.
Pulse CO-Oximetry SpO2 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 fingertip 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 following figure shows the general monitoring setup.

SpCO GENERAL DESCRIPTION Pulse CO-Oximetry is a continuous and noninvasive method of measuring the levels of carboxyhemoglobin (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 fingertip for adults and the hand or foot for infants. The sensor connects either directly to the Pulse CO-Oximetry instrument or through an instrument 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 reflect 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 of pulse oximetry (spectrophotometry) to make its SpMet measurement. The measurement is obtained by placing a sensor on a patient, usually on the fingertip for adults and the hand or foot for infants. The sensor connects either directly to the Pulse COOximetry instrument or through an instrument 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 SpMet.

PRINCIPLE 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).

Wavelength (nm)
2. The amount of arterial blood in tissue changes with your pulse (photoplethysography). Therefore, the amount of light absorbed by the varying quantities of arterial blood changes as well. The Rad-87 Pulse CO-Oximeter uses a multi-wavelength sensor to distinguish between oxygenated blood, deoxygenated blood, blood with carbon monoxide, oxidized blood and blood plasma. The Rad-87 utilizes a sensor with various light-emitting diodes (LEDs) that pass light through the site to a photodiode (detector). See figure below. Signal data is obtained by passing various visible and infrared lights (LED’s, 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 ≤ 25mW. The detector receives the light, converts it into an electronic signal and sends it to the Rad-87 for calculation.

PRINCIPLE OF OPERATION - (CONTINUED) Once the Rad-87 receives the signal from the sensor, it utilizes Masimo Rainbow SET signal extraction technology to calculate the patient’s functional arterial oxygen saturation, blood levels of carboxyhemoglobin (SpCO), methemoglobin (SpMet) and pulse rate. The SpCO and SpMet measurements rely on a multiwavelength calibration equation to quantify the percentage of carbon monoxide and methemoglobin in arterial blood. In an ambient temperature of 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 SATURATION The Rad-87 is calibrated to measure and display functional saturation (SpO2): the amount of oxyhemoglobin expressed as a percentage of the hemoglobin that is available to transport oxygen. Note that carboxyhemoglobin and methemoglobin are not capable of transporting oxygen, but is recognized as oxygenated hemoglobin by conventional pulse oximetry. RAD-87 vs. DRAWN WHOLE BLOOD MEASUREMENTS When SpO2, SpCO and SpMet measurements obtained from the Rad-87 (noninvasive) are compared to drawn whole blood (invasive) measurements by blood gas and/or laboratory COOximetry 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, SpCO, and SpMet measurements of the Rad-87 Pulse CO-Oximeter. 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 SpCO, different results are also expected if concentration of methemoglobin in the blood gas sample is abnormal (greater than 2% for methemoglobin concentration). High levels of bilirubin may cause erroneous SpO2, SpMet, and SpCO 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, SpCO and SpMet 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. MASIMO SIGNAL EXTRACTION TECHNOLOGY (SET) FOR SpO2 MEASUREMENTS 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 non-arterial 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®) 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. 1-6

SpMet AND SpCO MEASUREMENTS DURING PATIENT MOTION The Rad-87 displays measurements of SpCO and SpMet 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. When the Rad-87 does not have confidence in the value of a parameter due to poor signal quality caused by excessive motion or other signal interference, the measurement for the parameter will alternate with "---". FASTSAT FastSat enables rapid tracking of arterial oxygen saturation changes. Arterial oxygen saturation data is averaged using pulse oximeter averaging algorithms to smooth the trend. When the Rad-87 is set to FastSat “On”, the averaging algorithm evaluates all the saturation values providing an averaged saturation value that is a better representation of the patient’s current oxygenation status. With FastSat, the averaging time is dependent on the input signal.
