Section 1
Introduction
This manual describes the use and operation of the OXYPLETH Pulse Oximeter Monitor, Model 520A, from Novametrix Medical Systems Inc. OXYPLETH is a lightweight, easy to use, pulse oximeter designed to be used in a variety of clinical settings. It provides reliable measurement, display and alerts for, functional pulsatile oxygen saturation (SpO2) and pulse rate. The monitor can be powered from the AC Mains (line voltage) or from its rechargeable internal battery. Numerical and waveform information is presented on a bright Cold Cathode Display (CCD) with user adjustable contrast to optimize viewing angles. A simple menu system allows user selection of measurement and display options. Alerts are menu programmable or automatic. Numerical and plethysmogram displays are continually updated. Presence of a pulse is indicated audibly by a user selectable “beep”. Separate 24 hour trends for SpO2 and pulse rate are updated every 8 seconds. In addition, trend “events” and audible alarm status (Audio Off) are also stored in trend memory. The monitor is equipped with an RS232 serial output port for easy interfacing to external equipment. An optional Analog Output module provides analog outputs.
SpO2 Principles of Operation OXYPLETH measures oxygen saturation and pulse rate with sensors that contain red and infrared light sources, called LEDs. Since oxygen saturated blood absorbs different amounts of light at each wavelength (red and infrared) as compared to unsaturated blood, the amount of light absorbed by the blood in each pulse can be used to calculate oxygen saturation. The light energy from red (660 nm) and infrared (940 nm) LEDs is beamed through a sample cell-a pulsating vascular bed, the patient’s finger or toe for example. The remaining light energy not absorbed by the sample cell reaches a light receptor, called a photodiode, on the opposing side of the sensor. The data received at the photodiode is sent back to the monitor where it is split into its red and infrared components, digitized, processed by a microprocessor chip, and finally displayed as a numerical value for oxygen saturation and a plethysmogram. OXYPLETH is calibrated to display “functional” saturation. This differs from the “fractional” saturation value displayed by most co-oximeters Equation 1. Functional Saturation Calculation

Section 1
Indications and Usage
Functional saturation represents the amount of oxyhemoglobin as a percentage of the hemoglobin that can be oxygenated. Dysfunctional hemoglobins (COHb and METHb) are not included in the measurement of functional saturation. Pulse Rate is calculated by measuring the time interval between the peaks of the infrared light waveform. The inverse of this measurement is displayed as pulse rate. OXYPLETH must be used in conjunction with SuperBright™ saturation sensors. An INCOMPATIBLE PROBE display message indicates a non-SuperBright™ Sensor is in use.
Indications and Usage The OXYPLETH Pulse Oximeter Monitor, Model 520A, is intended to be used for monitoring oxygen saturation and pulse rate in all critical monitoring environments including ventilatory support and anesthesia. OXYPLETH is designed to monitor all patient areas including adult, pediatric and neonatal.

Patient Safety
The OXYPLETH Pulse Oximeter Monitor, Model 520A, SpO2 Input is electrically isolated. Patient leakage current flowing from the instrument to ground is limited to less than 10 PA at 120 VAC, 60 Hz. Patient isolation is greater than 10 M:, 2500 VAC rms at 60 Hz. For maximum patient and operator safety, the following are recommended: • • • • •
• •
Failure of Operation: If the monitor fails to respond as described, do not use it until the situation has been corrected by qualified personnel. Keep OXYPLETH and its accessories clean. Do not operate OXYPLETH when it is wet due to spills or condensation. Do not operate OXYPLETH if it appears to have been dropped or damaged. Connect the line cord only to a grounded hospital-grade outlet. OXYPLETH should be connected to the same electrical circuit as other equipment in use on the patient. Outlets on the same circuit can be identified by the hospital’s engineering department. Care should be exercised to assure continued peripheral perfusion distal to the SpO2 sensor site after application. Components of this product and its associated accessories which may have patient contact are free of latex.

Section 2
Cautions
•
Data Validity: Inaccurate SpO2 and/or Pulse Rate measurements can be caused by any of the following: • Incorrect application or use of a sensor • Significant levels of dysfunctional hemoglobin such as carboxyhemoglobin or methemoglobin • Significant levels of indocyanine green, methylene blue, or other intravascular dyes • Exposure to excessive illumination such as surgical lamps-especially ones with a xenon light source, or direct sunlight • Excessive patient movement, venous pulsations, electrosurgical interference
•
•
•
Data Validity: The Pulse Oximeter should not be used as a substitute for an ECG monitor. The oximeter’s Pulse Rate display reflects the pulsatile flow found at the patient extremity connected to the sensor. This rate can be affected by many factors and may occasionally be “frozen.” Do NOT attach an SpO2 sensor distal to a blood pressure cuff. Valid data CANNOT be processed when the cuff is inflated. Attach the sensor to the limb opposite to the site used for the blood pressure cuff. Do NOT apply Y-Sensor tapes or wraps so tightly that the circulation is restricted. Inspect site often for adequate circulation - at least once every four hours. When applying sensors take note of the patient’s physiological condition. For example, burn patients may exhibit more sensitivity to heat and pressure and therefore additional consideration such as more frequent site checks may be appropriate.
Cautions CAUTION Indicates a condition that may lead to equipment damage or malfunction. • • • • • •

Do not operate OXYPLETH when it is wet due to spills or condensation. Do not operate OXYPLETH if it appears to have been dropped or damaged. Never sterilize or immerse the monitor in liquids. Do not sterilize or immerse sensors except as directed in this manual. Tension should not be applied to the sensor cable. Overstretching the pulse oximeter finger sensor can damage the sensor and potentially affect pulse oximeter readings. Do not stretch the finger sensor open beyond the limit for which it was designed. Overstretching can be prevented: avoid opening the sensor by any means other than squeezing the grips; Do NOT force the sensor onto large objects such as the bed rail. Do not store the monitor or sensors at temperatures less than 14q F (-10q C) or greater than 131q F (55q C). Do not operate the monitor or sensors at temperatures less than 50q F (10q C) or greater than 104q F (40q C). Federal (U.S.A.) law restricts this device to sale, distribution, or use by or on the order of a licensed medical practitioner.

Monitor Basics
AC Mains (Line Cord) and Battery Power OXYPLETH can operate from AC Mains (line cord) power or from its internal battery.
AC Operation The rear panel power input module must be set to the proper voltage setting and the proper fuses must be installed for safe AC Mains (line cord) operation. The module should indicate the proper voltage setting (115 VAC for use in the U.S.A.) Refer to the OXYPLETH Service Manual if this setting needs to be changed. To operate from AC Mains (line cord) power, plug the line cord into the rear panel power input connector and set the rear panel POWER switch to “|”. Connect the other end of the line cord to a properly grounded three-wire outlet.
Battery Operation OXYPLETH can operate for up to three hours while powered from its internal battery (excessive alerting reduces battery life). The monitor is powered from its internal battery whenever the line cord is disconnected or the rear panel POWER switch is set to the “0” (off) position. While on battery power, OXYPLETH displays a battery icon to the left of the Signal Bar. indicates a fully charged battery, a half charge, and indicates less than 30 minutes of battery life remain. Note: The battery icon appears fully charged for the first minute after switching to battery power; after that it will reflect the true battery charge. When approximately 15 minutes of battery life remain, the front panel LOW BAT indicator illuminates. Reconnect the monitor to the AC Mains to recharge the battery. The monitor can be operated from the AC Mains while the battery is being recharged. The battery will be fully recharged in 12-15 hours. If the monitor continues operating on battery power while in the low battery state ( illuminated), the battery becomes exhausted and the monitor stops operating. The message BATTERY VERY LOW PLUG IN AC POWER is displayed and a continuous audible tone will sound. The audible tone cannot be silenced, the monitor must be connected to AC Mains for continued operation and to recharge the battery. If the monitor is allowed to continue operation while in the battery exhausted state, the monitor will automatically shut itself off to avoid excessive discharge and damage to the battery.
