SECTION 1: INTRODUCTION1.11.21.31.1Manual OverviewWarnings, Cautions, and NotesProduct DescriptionMANUAL OVERVIEWThis manual contains information for servicing the handheld capnograph/pulse oximeter (the monitor). Only authorized service personnel shouldservice this product. The Handheld Capnograph/Pulse OximeterOperator’s Manual (the operator’s manual) is an integral part of theservice procedures. Before servicing the monitor, read the operator’smanual carefully for a thorough understanding of how to operate the unit.Only use the tools and test equipment as specified in this manual. Onlyuse original spare parts available from your local distributor.Warning: Incorrect procedures may harm the patient, ordamage the monitor.1.21.2.1WARNINGS, CAUTIONS, AND NOTESWarningA warning precedes an action that may result in injury or death to thepatient or user. Warnings are boxed and highlighted in boldface type.1.2.2CautionA caution precedes an action that may result in damage to, or malfunctionof, the monitor. Cautions are highlighted in boldface type.1.2.3NoteA note gives information that requires special attention.1-1
Section 1: Introduction1.3PRODUCT DESCRIPTIONThe handheld capnograph/pulse oximeter is used to continuously monitorend-tidal carbon dioxide (EtCO2), respiratory rate, oxygen saturation(SpO2), and pulse rate. The monitor is for attended monitoring only andmust be used in the continuous presence of a qualified healthcareprovider. The monitor can be used on adult, pediatric, and infant/neonatalpatients. It is intended for use where continuous, noninvasive monitoringof these parameters is desired, including hospital and mobile use (whenprotected from excessive moisture such as direct rainfall). The monitoroperates on AC power or a rechargeable Nickel Metal Hydride batterypack.Figure 1-1: Handheld Capnograph/Pulse OximeterThe monitor is operated using a four-key keypad. Measurements aredisplayed on the front panel on the 7-segment LED digital displays (LED)and on the LCD graphic display (LCD) as shown in Figure 1-2. Refer to theoperator’s manual for complete operating instructions.Figure 1-2: LCD Graphic Display and 7-Segment Digital Displays1-2
SECTION 2: REQUIRED EQUIPMENT2.12.1Required EquipmentREQUIRED EQUIPMENTYou will need the following equipment to disassemble, replace parts,check, adjust, or calibrate the monitor.For disassembly and replacement: Phillips-head screwdriver (medium) Flat-head screwdriver (small) IC Extractor for PLCC socket Threadlocker glue e.g. Loctite 222 super screw lockFor checks, adjustments and calibration: Calibration Gas (5% CO2 in air) FilterLine or FilterLine H and a connecting means DS-100A - OXIMAX Durasensor , Nellcor Leak Test Jig Vacuum manometer with a range of 0-500 mBare.g. MPL-3200-DM, Digital Manometer MicroPneumatic Logic, Inc. Communication Adapter Kit (only necessary to verify print functions) Seiko DPU-414 printer (only necessary to verify print functions) External power supply Handheld Capnograph/Pulse Oximeter Operator’s Manual Flow Meter (range 0-50 ml/min) e.g. Top Track Mass Flow Meter,model: 822-13-OV1-PV1-V1, Sierra Instruments, Inc.Warning: Observe ESD (electrostatic discharge) precautionswhen handling, adjusting or performing any procedure withthe monitor’s internal components.2-1
SECTION 3: CLEANING3.13.1CleaningCLEANINGAlways clean the outer surface of the monitor before servicing.Warning: Always wear latex or surgical gloves when cleaningor servicing the monitor after hospital use.Warning: Do not allow liquids to drip inside the housing.Warning: Do not clean internal components.Warning: Do not use preparations based on: phenols, halogenproducing compounds, strong organic acids, or oxygenproducing compounds.3.1.1Procedure1.Unplug the unit from AC power.2.With a damp cloth, gently wipe the outer case of the monitor with adisinfectant based on aldehyde, alcohol or quaternary ammoniumproducing compounds.3-1
SECTION 4: SERVICE MODE4.14.24.34.1IntroductionService Level 1Service Level 2INTRODUCTIONThe monitor supports a service mode built into the instrument’s firmware.To access the service mode, refer to Table 4-1: "Accessing Service Modeand Changing Parameter Settings".The architecture of the monitor’s service mode divides the service modeinto two levels as described in the sections below. Service Level 1 Service Level 24.2SERVICE LEVEL 1The Service Level 1 provides information and tools on three servicescreens to test and calibrate specific functions without disassembling themonitor. Information Screen Event Messages Screen Interface Test ScreenFrom these display screens the service technician can check the operatinghours counter and event messages, test the Human Interface functions(HMI), set the light detection threshold, adjust the LCD contrast middlepoint and do a calibration check and a calibration process, if necessary.Refer to Table 4-1: "Accessing Service Mode and Changing ParameterSettings".4.2.1Information ScreenThe information screen displays the monitor’s main board serial number,the number of operating hours, and the SpO2 and C O2 boards’ softwareversions.4.2.2Event Messages ScreenThe monitor automatically performs a series of built-in tests (BITs) atstart-up and during operation to check sub-systems and modules forerrors. The event messages screen lists the last five event messages, thetime each occurred relative to the unit’s operating hours, and arecommended service action. There are three event messages and eachhas a specific response as follows:Event Message:Action:CO2 boardSpO2 boardFlowReplace CO2 boardReplace SpO2 boardReplace CO2 board4-1
Section 4: Service ModeNote:4.2.3To exit the service mode and save event messages, turn off themonitor. Event messages will be erased when exiting the servicemode by a long press of.Interface Test ScreenThe interface test screen shows four parameters (listed below) thatprovide tools for the user to test, adjust, and calibrate the unit’sinterfacing systems. HMI Test Light Detector Contrast Cal. (Calibration) CO2 Calib. (Calibration)4.2.3.1 HMI TestWhen the HMI Test is turned on, the monitor performs a self-test of thefollowing sub-systems: Buzzer (sounds for one second) LCD graphic display (screen shows a checkerboard pattern) 7-segment digital display (8s scroll left to right) Alarm bar (lights red, yellow, off) Backlight (turns on and off) Alarm silence indicator (light turns on and off)When the HMI test is completed the status field returns automatically toOFF.4.2.3.2 Light DetectorThe Light Detector parameter allows the service technician to set thethreshold value of the phototransistor. The default value is 1 and therange is from 1 to 5 with 1 as the most sensitive (backlight on at all times)and 5 as the least sensitive (backlight off). The threshold value should beset according to the lighting conditions of the working environment. Ahigher threshold value saves on battery power consumption.4.2.3.3 Contrast Cal. (calibration)The Contrast Cal. gives the service technician the option to change themiddle point default value of the contrast intensity of the LCD. Refer toTable 4-1: "Accessing Service Mode and Changing Parameter Settings".4.2.3.4 CO2 Calib. (calibration)The CO2 Calib. allows the service technician to perform a calibrationcheck and calibration process to ensure the accuracy of the monitor.Section 10: Performance Verification describes the calibration checkprocedure.4-2
Section 4: Service Mode4.2.4Accessing Service Mode and Service Level 1.Table 4-1: "Accessing Service Mode and Changing Parameter Settings"describes the process to access the service mode, change parametersettings and how to change Contrast Cal. settings.Table 4-1: Accessing Service Mode andChanging Parameter SettingsObjectiveActionResponseTo access Service Mode During self-test,long presssimultaneouslySelf-test occurs and theInformation Screenappears:andTo access EventMessages screenlong pressTo access InterfaceTest screenlong pressTo change theparameter setting orvalueshort pressTo move to the nextparametershort press4-3
