Operators Manual Multi-parameter Patient Monitor " LifeWindow Lite LW8 " 31 Digicare Biomedical Technology SECTION 6 – CO2 MONITORING A. OVERVIEW • The LifeWindow™ Lite LW8 Patient Monitor has a plug and play CO2 technology, with MicroFlow™ sidestream CO2, MainFlow™ mainstream CO2 and Dual Capnography, designed with sophisticated infrared absorption spectroscopy. • The Micro-Flow™ sidestream module can be assembled internally in the unit or it can be one small and lightweight external module. The sample lines used are the same for both internal and external Micro-Flow™ sidestream modules. • The MainFlow™ mainstream sensor is assembled in the air way adapter. The connection of the MainFlow™ mainstream sensor is the same as the external Micro-Flow™ sidestream CO2 module. • The Dual Capnography is enabled by the interchangeability of the Micro-Flow™ sidestream and MainFlow™ mainstream external sensors. The LifeWindow™ Lite LW8 automatically recognize what type of CO2 external sensor is connected and configures the CO2 function. • The LifeWindow™ Lite LW8 with internal Micro-Flow™ sidestream module does not have the connection for the external Micro-Flow™ sidestream and the MainFlow™ mainstream sensor. SECTION 6.1 – MAINSTREAM CO2 MONITORING A. Principle of Operation • The LifeWindow™ Lite LW8 MainFlow™ mainstream CO2 sensor is used for the continuous measurement of CO2 and respiratory rate. The sensor measures CO2 by using the infrared absorption technique. The principle is based on the fact that CO2 molecules absorb infrared (IR) light energy of specific wavelengths, with the amount of energy absorbed being directly related to the CO2 concentration. When an IR beam is passed through a gas sample containing CO2, the electronic signal from the photodetector (which measures the remaining light energy) is measured. This signal is then compared to the energy of the IR source and adjusted to accurately reflect CO2 concentration in the sample. The MainFlow™ mainstream CO2 sensor’s response to a known concentration of CO2 is stored at the factory in the sensor’s memory. A reference channel accounts for optical changes in the sensor, allowing the system to remain in calibration without user intervention. • The LifeWindow™ Lite LW8 MainFlow™ mainstream CO2 sensor is designed specifically for measurement of CO2 using sophisticated infrared absorption spectroscopy. With mainstream, measurements are taken at the patient’s airway at a sampling frequency of 100 Hz, so response is faster and there is less chance of erroneous, artifact data. The analyzer portion of the sensor cannot be contaminated with patient secretions, and there are no pumping or pneumatic components to replace. So, maintenance requirements and overall cost-of-ownership are minimized. The family of airway adapters are easy to use and durable enough even for long-term ventilator patients. B. Indications for Use • The MainFlow™ mainstream CO2 Sensor is to be used by a physician or licensed health care professional trained in the use of the equipment. Operators Manual Multi-parameter Patient Monitor " LifeWindow Lite LW8 " 32 Digicare Biomedical Technology • The use of the MainFlow™ mainstream CO2 Sensor is contraindicated in patients where the physician or licensed health care professional deems it invalidated by the nature of the patient, procedure or equipment. WARNINGS • Explosion Hazard: DO NOT use in the presence of flammable anesthetics. Use of the MainFlow™ mainstream CO2 Sensor in such environment may present an explosion hazard. • Electrical Shock Hazard: Always disconnect the MainFlow™ CO2 Sensor before cleaning. Do NOT use if it appears to have been damaged. Refer servicing to qualified service personnel. • Follow precautions for electrostatic discharge (ESD) and electromagnetic interference (EMI) to and from other equipment. • Failure of Operation: If the MainFlow™ mainstream CO2 Sensor fails to respond as described in this user guide; DO NOT use it until approved for use by qualified personnel. • DO NOT position the sensor cables or tubing in any manner that may cause entanglement or strangulation. Support the mainstream CO2 airway adapter to prevent stress on the ET tube. • Reuse, disassembly, cleaning, disinfecting or sterilizing the single patient use CO2 airway adapters may compromise functionality and system performance leading to a user or patient hazard. Performance is not guaranteed if an item labeled as single patient use is reused. • Inspect the CO2 airway adapters for damage prior to use. DO NOT use the CO2 airway adapters if they appear to be damaged or broken. • Replace the CO2 airway adapters if excessive secretions are observed. • If the CO2 waveform (Capnogram) appears abnormal, inspect the CO2 airway adapters and replace if needed. • Monitor the CO2 waveform (Capnogram) for elevated baseline. Elevated baseline can be caused by sensor or patient problems. • Periodically check the MainFlow™ CO2 sensor and tubing for excessive moisture or secretion buildup. • While using the MainFlow™ CO2 sensor, a system leak, such as that caused by an uncuffed Endotracheal tube or a damaged MainFlow™ CO2 sensor may significantly effect flow-related readings.

Operators Manual Multi-parameter Patient Monitor " LifeWindow Lite LW8 " 44 Digicare Biomedical Technology SECTION 7 - NIBP MONITORING A. CUFF SELECTION AND PLACEMENT The use of properly designed and sized cuffs is essential for the accurate non-invasive measurement of blood pressure. The widest cuff that can be placed around the limb should be used. A cuff that is too small for the limb will not supply sufficient occlusion pressure to the artery. This can cause an erroneously high blood pressure reading. Ideally, cuff width should be 40% of the limb circumference. Substitution of a cuff different from that supplied might result in a measurement error. NOTE: Overlapping the cuff will not affect the measurement results. • For best results, a cuff should be wrapped for a snug fit and be positioned reasonably close to heart level. Measurements made above the level of the heart will give reduced blood pressure readings. Measurements made below the heart level will give increased readings. NOTE: Avoid compression or restriction of the NIBP Inflation Hose. The hose must not be kinked or pinched. WARNING: The cuff should not be applied on a limb being used for an intravenous infusion. Do not place the cuff on any extremity being used for SpO2 monitoring. CUFF SIZE SELECTION • The widest cuff that can be placed on the patient, without extending beyond the joint, should be selected. Appropriate sized cuffs may be selected based on published guidelines that cuff width should be 40 – 60% of limb circumference. The cuff should be wrapped for a snug fit. • Overlapping the cuff will not affect measurement results. Make sure the hook and loop sections of the cuff are fully engaged when it is wrapped around the limb. If not fully engaged, the cuff will detach during bladder inflation. If that happens, select the next size bigger cuff. • The correct selection of cuff size have a significant influence measurement accuracy. A cuff that is too narrow will produce artificially elevated readings, while a cuff that is too wide wi ll produce spuriously low values. • The monitor comes standard with six different sizes of cuffs. They are marked to aid in proper cuff selection. When a cuff is wrapped around a site, its index edge should be in the range indicated on the cuff. The cuff is too small or too large if the index edge is outside the range. Arm Locate the cuff as you would to do an auscultatory blood pressure. Place the cuff around the patient’s upper arm with the bottom edge of the cuff at least one inch above the inner aspect of the arm. As the cuff is wrapped around the arm, be sure it fits snugly and evenly, and the bladder of the cuff is over the brachial artery. Thigh Place the cuff around the patient’s thigh with the bottom edge of the cuff at least one inch above the inner aspect of the knee. Be sure the cuff fits snugly and evenly, and the bladder of the cuff is over the popliteal artery.

PRINCIPLE OF OPERATION • The LifeWindow™ Lite LW8 provides fast and accurate oxygen monitoring. It is designed to monitor up to 100% oxygen concentration in medical gas mixtures. It is capable of rapidly measuring the oxygen content of an atmosphere or environment. • The LifeWindow™ Lite LW8 is intended to continuously measure and display the Concentration of oxygen in a gas mixtures used in medical applications such as Anesthesia and Respiratory therapy in veterinary patients. B. PATIENT CONNECTIONS • The LifeWindow™ Lite LW8 uses one polarographyc oxygen sensor. Attached to the sensor is a removable plastic diverter. This diverter is used to facilitate the transport of gas mixtures Operators Manual Multi-parameter Patient Monitor " LifeWindow Lite LW8 " 54 Digicare Biomedical Technology through the sensor. The diverter, packaged separately when shipped, is necessary when the tee adapter is used to sample gas flowing through a tube. The diverter is not necessary and should not be used when the sensor is placed directly in a chamber, or when the sensor is used in confined volume monitoring, such as incubators and inhalation tents. 1 - SENSOR INSTALLATION OR REPLACEMENT • Remove the new sensor from its protective bag. Inspect the sensor for damage or electrolyte leakage. If the sensor is damaged, obtain a replacement. Do not use the defective sensor as it may damage the unit. • WARNING: The sensor electrolyte is caustic. Do not let it come in contact with skin. If it does, flush affected area with water. Do not attempt to open or repair the sensor. • WARNING: The sensor also contains lead. Leaking or exhausted sensors should be handled and disposed of in accordance with local regulations. • Connect one end of the FIO2 patient cable into the jack receptacle on the back end of sensor. • Connect the other end of the cable into the receptacle (15) located on the patient connections panel of the unit.

CALIBRATION • The LifeWindow™ Lite LW8 should be calibrated before each use and every 8 hours to maintain maximum accuracy. 1 – ONE POINT CALIBRATION • As with most oxygen analyzer(s) the highest level of accuracy is achieved when calibration is conducted using 100% oxygen. • One Point Calibration procedure is used as a option when a 100% oxygen is not available. • After installing the flow diverter keep the oxygen sensor exposed to fresh air. • The actual FIO2 reading will be displayed and it should be close to the local atmospheric oxygen content ( ex. 21% ). • Touch the FIO2 menu and select CAL 1 Point. The message: “Are you sure you want to make a 1 point calibration on FIO2?” is displayed. Press Yes. • In the Low Point FIO2 Calibration screen, select the O2 concentration (default 21%). Make sure the oxygen sensor is exposed to the selected O2 concentration and press enter to start calibration. The FIO2 reading will change to the Value selected. 2 – TWO POINT CALIBRATION • As with most oxygen analyzer(s) the highest level of accuracy is achieved when calibration is conducted using Two Point Calibration with 100% oxygen. • After installing the flow diverter keep the oxygen sensor exposed to fresh air. • The actual FIO2 reading will be displayed and it should be close to the local atmospheric oxygen content ( ex. 21% ). • Touch the FIO2 menu and select CAL 2 Point. The message: “Are you sure you want to make a 2 point calibration on FIO2?” is displayed. Press Yes. • In the Low Point FIO2 Calibration screen, select the O2 concentration (default 21%). Make sure the oxygen sensor is exposed to the selected O2 concentration. • Select in the High Point FIO2 Calibration screen the second calibration point (100% default). • Expose the oxygen sensor to the selected O2 concentration (default 100%) supply of pure dry oxygen flowing at 1 – 2 liters per minute. Wait about 20 seconds to insure the sample line is completely purged with the calibration gas and press Enter to calibrate. • Remove the sensor from the oxygen supply and confirm the FIO2 indicator reads less than 22% in room air. • It is important to perform the calibration carefully and thoroughly, using calibration gases that are free from contaminates. Wait for a stable reading before locking in calibration point. 3 – DEFAULT CALIBRATION • The Default Calibration procedure returns the FIO2 function calibration to factory default calibration. • To return the FIO2 function to the factory default calibration touch the FIO2 menu and touch the Cal Default button. D. FIO2 MONITORING • The LifeWindow™ Lite LW8 can be used to measure a gas mixture for oxygen in two basic modes: • In the inhalation side of breathing circuit ahead of humidifiers and medicating devices or other instances where gases are flowing to a patient in breathing circuits. When monitoring oxygen in breathing circuits, the flow diverter must be used. • In confined volumes such as tents and hoods. In these applications the flow diverter must be removed from the sensor so that it does not interfere with the rapid exchange of gases to and from the sensing surface of the sensor. Operators Manual Multi-parameter Patient Monitor " LifeWindow Lite LW8 " 56 Digicare Biomedical Technology • CAUTION: Check the breathing circuit for leaks. Be certain that the circuit downstream of the sensor does not produce any backpressure or restriction to flow. Errors in readings will result if this is not followed. • Never install the sensor in a location that will expose the sensor to patients exhaled breath or secretrions unless you intend to dispose of the sensor and flow adapter after use. 1 - GAS SAMPLING 1.1 - HUMIDITY • Humidity does not directly affect the accuracy of the sensor's measurement. However, when a nebulizer or other device is used to increase moisture levels in gas mixtures, the moisture actually dilutes the mixture. This dilution effect decreases the oxygen concentration. The LifeWindow™ Lite LW8 oxygen monitor accurately measures decreases in the oxygen concentration due to the dilution effects of moisture added to gas mixtures. • As with all oxygen sensors, excessive condensation on the sensing surface will block the diffusion of oxygen to the sensor, rendering it inoperative. We recommend installing the sensor on the dry side of the breathing circuit at all times. 1.2 - TEMPERATURE • The oxygen sensor adjusts for ambient temperature changes in the range of 0–40°C (32– 106°F). Since the thermistor that compensates for these changes is located in the rear of the sensor assembly, it is important that gas mixtures, flowing over the front of the sensor, be at room temperature. Reading errors may occur if hot gases from a heated humidifier are directed past a sensor teed into a breathing circuit. 1.3 - PRESSURE • Virtually all gas sensors and monitors measure the partial pressure, not the percentage, of the gas that they sense. The only time that these instruments can accurately read percentages is when the total pressure does not vary over time between calibrations and use. For this reason it is important to calibrate the LifeWindow™ Lite LW8 oxygen sensor at regular intervals. It is recommended that the unit be calibrated prior to each use or every 8 hours. • When the sensor is connected to a ventilator circuit, the alternating “breathing” pressure cycles generated by the ventilator will be sensed as an increase in the oxygen percentage. In reality, the percentage of oxygen is not changing; it is the total pressure that is increasing producing a corresponding increase in the partial pressure of oxygen. A hundred centimeter of water pressure pulse will produce a 0.11 atmosphere, or an 11% increase in the total and therefore partial pressure of oxygen. The reading will rise proportionally less for smaller pressures. 1.4 - ANESTHETIC GASES • When using the LifeWindow™ Lite LW8 oxygen sensor in the presence of anesthetic gases such as Isoflurane, the oxygen reading may fall (see Table below). The magnitude of this error will depend upon the level of oxygen and the duration of exposure. Halothane 4% < 1.5% O2 Enflurane 5% < 1.5% O2 Isoflurane 5% < 1.5% O2 Sevoflurane 5% < 1.5% O2 Desflurane 15% < 1.5% O2 Note: Errors are approximate and may vary based on exposure times and concentrations. These performances meet or exceed the requirements of ISO 7767: 1997 (E). Caution: The LifeWindow™ Lite LW8 should not be used in the presence of flammable anesthetics such as diethyl ether or cyclopropane.
