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.

Rad-8 Signal Extraction Pulse Oximeter Operator’s Manual

Once the Rad-8 receives the signal from the sensor, it utilizes Masimo SET signal extraction technology for calculation of the patient’s functional oxygen saturation and pulse rate. The maximum of the skin surface temperature is measured at an ambient temperature of less than 106º F (41º C).This is verified by Masimo sensor skin temperature test procedures.

The Rad-8 pulse oximeter uses a two-wavelength pulsatile system to distinguish between oxygenated and deoxygenated blood. Signal data is obtained by passing red (rd) (660 nm wavelength) and infrared (ir) (905 nm wavelength) light through a capillary bed (for example a fingertip, a hand or a foot) and measuring changes in light absorption during the pulsatile cycle. This information may be useful to clinicians. The radiant power of the light is rated at 0.79mW (max.). See figure below. The Rad-8 utilizes a sensor with red and infrared light-emitting diodes (LEDs) that pass light through the site to a photodiode (photodetector). The photodetector receives the light, converts it into an electronic signal and sends it to the Rad-8 for calculation.

Oxyhemoglobin (oxygenated blood) and deoxyhemoglobin (non-oxygenated blood) differ in their absorption of red and infrared light (spectrophotometry).

Pulse Oximetry GENERAL DESCRIPTION Pulse oximetry is a continuous and non-invasive 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 connects to the pulse oximetry instrument directly 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 in two ways:

Rad-8 Signal Extraction Pulse Oximeter Operator’s Manual

MASIMO SET SIGNAL EXTRACTION TECHNOLOGY Masimo Signal Extraction Technology’s signal processing differs from 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.

MEASURED VS. CALCULATED SATURATION Oxygen saturation measurements obtained from a pulse oximeter are commonly compared to saturations calculated from the partial pressure of oxygen (PO2) obtained from an arterial blood gas sample. When comparing the two measurements and interpreting values, caution should be used, as the calculated value obtained from the blood gas sample may differ from the SpO2 measurement of the pulse oximeter. Different results are usually obtained from the blood gas sample if the calculated saturation is not appropriately corrected for the effects of variables that shift the relationship between PO2 and saturation, such as: pH, temperature, the partial pressure of carbon dioxide (PCO2), 2,3-DPG, and fetal hemoglobin. Also, as blood gas samples are usually taken over a period of 20 seconds (the time it takes to draw blood) a meaningful comparison can only be achieved if the core oxygen saturation of the patient is stable and not changing over the period of time that the blood gas sample is taken.

Functional saturation =

FUNCTIONAL VS. FRACTIONAL SATURATION The Rad-8 is calibrated to measure and display functional saturation which is the amount of oxygenated hemoglobin expressed as a percentage of the hemoglobin that can transport oxygen. The Rad-8 does not measure fractional saturation which is oxygenated hemoglobin expressed as a percentage of all measured hemoglobin. This includes measured dysfunctional hemoglobin such as carboxyhemoglobin or methemoglobin. To convert fractional saturation to functional saturation, the fractional saturation measurements must be converted according to:

DO NOT IMMERSE THE SENSOR IN WATER, SOLVENTS, OR CLEANING SOLUTIONS (THE SENSORS AND CONNEC TORS ARE NOT WATERPROOF). DO NOT STERILIZE BY IRRADIATION, STEAM, AUTOCLAVE OR ETHYLENE OXIDE (UNLESS OTHERWISE INDICATED ON THE SENSOR DIRECTIONS FOR USE). SEE THE CLEANING INSTRUCTIONS IN THE DIRECTIONS FOR USE FOR REUSABLE MASIMO SENSORS.

■

CAUTIONS

Tissue damage can be caused by incorrect application or use of an LNOP, LNOPv or LNCS sensor, for example by wrapping the sensor too tightly. Inspect the sensor site as directed in the sensor Directions for Use to ensure skin integrity and correct positioning and adhesion of the sensor.

Use only Masimo oximetry sensors for SpO2 measurements.

MASIMO SENSORS Before use, carefully read the LNOP, LNOPv and LNCS sensor Directions for Use.

NUMERIC DISPLAY - SpO2 Stability of the SpO2 readings may be a good indicator of signal validity. Although stability is a relative term, experience will provide a good feeling for changes that are artifactual or physiological and the speed, timing, and behavior of each. The stability of the readings over time is affected by the averaging mode being used. The longer the averaging time, the more stable the readings tend to become. This is due to a dampened response as the signal is averaged over a longer period of time than during shorter averaging times. However, longer averaging times delay the response of the oximeter and reduce the measured variations of SpO2 and PR.

Place the sensor on a site that is not too thick, has sufficient perfusion and provides proper alignment of the LED’s and photodetector.

■

The following general points will aid in ensuring oximetry monitoring success.

Successful SpO2 monitoring

operation

Rad-8 Signal Extraction Pulse Oximeter Operator’s Manual

NUMERIC DISPLAY - PULSE RATE The Pulse Rate displayed on the Rad-8 may differ slightly from the heart rate displayed on ECG monitors due to differences in averaging times. There may also be a discrepancy between cardiac electrical activity and peripheral arterial pulsation. Significant differences may indicate a problem with the signal quality due to physiological changes in the patient or one of the instruments or application of the sensor or patient cable. The pulsations from intra-aortic balloon support can be additive to the pulse rate displayed on the pulse oximeter.

operation

4-5

4-6

Check the sensor and ensure proper sensor application. The sensor must be well secured to the site for the Rad-8 to maintain accurate readings. Also, misalignment of the sensor’s emitter and detector can result in smaller signals.

Determine if an extreme change in the patient’s physiology and blood flow at the monitoring site occurred, (e.g. an inflated blood pressure cuff, a squeezing motion, sampling of an arterial blood specimen from the hand containing the pulse oximetry sensor, severe hypotension, peripheral vasoconstriction in response to hypothermia, medications, or a spell of Raynaud’s syndrome.)

With neonates or infants, check that the peripheral blood flow to the sensor site is not interrupted. Interruption, for example, as may occur while lifting or crossing their legs, during a diaper change.

■

Rad-8 Signal Extraction Pulse Oximeter Operator’s Manual

After performing the above, if the “Low Signal IQ” indication occurs frequently or continuously, obtaining an arterial blood specimen for CO-Oximetry analysis may be considered to verify the oxygen saturation value.

Assess the patient.

■

The height of the Signal IQ bar indicates the quality of the measured signal. A high vertical bar indicates that the SpO2 measurement is based on a good quality signal. A small vertical bar indicates that the SpO2 measurement is based on data with low signal quality. When the signal quality is very low the accuracy of the SpO2 measurement may be compromised. A “Low Signal IQ” is indicated by a bar height of two bars or less and the bars turn red. When this occurs, proceed with caution and do the following:

The Signal IQ is shown as a “bouncing bar” indicator, where the peak of the bar coincides with the peak of an arterial pulsation. Even with a plethysmographic waveform obscured by artifact, the Rad-8 locates the arterial pulsation. The pulse tone (when enabled) coincides with the peak of the Signal IQ bar. As saturation increases or decreases, the pulse tone will ascend or descend accordingly, for each 1% change in saturation.

SIGNAL IQ AND PULSE BAR The Rad-8 display provides a visual indicator of the plethysmogram signal quality and an alert when the displayed SpO2 values are not based on adequate signal quality. The signal quality indicator displayed on the Rad-8 is called the Signal IQ. The Signal IQ can be used to identify the occurrence of a patient’s pulse and the associated signal quality of the measurement.

operation

Rad-8 Signal Extraction Pulse Oximeter Operator’s Manual

CAUTION: IF ANY MEASUREMENT SEEMS QUESTIONABLE, FIRST CHECK THE PATIENT’S VITAL SIGNS BY ALTERNATE MEANS AND THEN CHECK THE PULSE OXIMETER FOR PROPER FUNCTIONING.

If possible, ensure that the sensor is placed in a location with low ambient light. Although the Rad-8 pulse oximeter integrated with Masimo SET technology has significant immunity to ambient light, excessive ambient light may cause readings to be incorrect.

If possible, remove electrical noise sources such as electrosurgical units or other electrical/electronic equipment.

■

Wipe the sensor site with a 70% isopropyl alcohol pad or rubefacient cream (1030% methyl salicylate and 2-10% menthol) for 20-30 seconds. Strong vasodilator creams, such as nitroglycerin paste, are not recommended.

■

If artificial nails or excessive fingernail polish are present, select another site or remove the polish/artificial nails.

Select a site where the distance between the emitter and photodetector is minimized.

■

Make sure the emitter and photodetector are aligned directly opposite each other.

■

ACTIONS TO BE TAKEN If the SpO2 readings show significant differences, do the following:

Vasoconstriction. Anesthesiology 1990; 73:532-537

CAUTION: IF THE LOW PERFUSION INDICATION IS FREQUENTLY DISPLAYED, FIND A BETTER-PERFUSED MONITORING SITE. IN THE INTERIM, ASSESS THE PATIENT AND, IF INDICATED, VERIFY OXYGENATION STATUS THROUGH OTHER MEANS.

It has been suggested that at extremely low perfusion levels, pulse oximeters can measure peripheral saturation, which may differ from central arterial saturation1. This “localized hypoxemia” may result from the metabolic demands of other tissues extracting oxygen proximal to the monitoring site under conditions of sustained peripheral hypoperfusion. (This may occur even with a pulse rate that correlates with the ECG heart rate.)

LOW PERFUSION The Rad-8 indicates perfusion on a 10-bar LED indicator. The lower two segments of the bar will turn red when the amplitude of the arterial pulsations is very low (low perfusion).
