6.5 Reports and Printing The Vitalograph micro can print pdf reports by connecting it to a PC running the Vitalograph Reports application. The micro has to be in the home screen to connect. 1. To produce PDF reports from the micro, ensure that the software is installed on the PC you wish to report to by running the Vitalograph Reports CD supplied with the micro and following the on­screen instructions. 2. The micro can be connected to the PC either using the USB cable supplied with the device, or for the Bluetooth version a Bluetooth dongle may be used. 3. Ensure that Vitalograph reports is open and the micro is switched on and in the home screen. 4. Additional guidance on using Vitalograph Reports can be found in the Vitalograph Reports help menu or in the 07339 User Training Manual on the supplied CD. Note: When the micro is connected to Vitalograph Reports it will move, not copy, the stored sessions with the exception of the latest FVC Pre­session. Note: Different tests conducted during the same session i.e VC, FVC, Post will be treated as a single session and will be printed as one report. If more than one test is required for the same subject the device should be switched off and on again between tests so that they are registered as separate sessions and separate reports can be generated.

6.6 Storing Results The Vitalograph micro has the capacity to store 750 subject entries with the corresponding session data. It is possible to perform up to 20 blows per session, however only a maximum of the best 3 blows will be stored with each session. The session information will also include the subject details and the best pre­test if it is a Post test session. The Vitalograph micro is intended to be used as a temporary storage device. The Vitalograph micro can be connected to Vitalograph Reports to produce pdf reports of the session data, this will move all subject/sessions to Vitalograph Reports and flag them as deleted on the device with the exception of the last FVC Pre­test done. This is outlined in more detail in section 6.5. If more than 750 subject/session entries are stored on the device the existing subject/sessions entries will be deleted on a First In First Out (FIFO) basis i.e the first session entered will be the first to be deleted. Any subjects/sessions previously flagged as deleted by Vitalograph Reports will be counted in the total storage available.

6.7 Accuracy/Calibration The Vitalograph micro should never be outside accuracy limits unless damaged or in a fault condition. In this event, see the fault­finding guide. In normal use, calibration traceability certification is recommended as a part of the routine annual service. It is recommended that you perform an accuracy check on the device and check the temperature daily. ISO26782 recommendations require that the difference between the volume measured by the spirometer and the volume pumped into the spirometer from a syringe is within 3%. Follow these steps to check the accuracy of the unit. 1. Select the Configuration button on the top right corner of the main menu screen. 2. Select the Accuracy/Calibration icon. 3. Enter the Syringe volume and reference using the touch panel keypad. 4. Enter the ambient temperature using the touch panel keypad. 5. Pump air through the flowhead to bring it to ambient temperature. If the flowhead has very recently been used for testing or has come from a cold environment, its temperature should be equilibrated with ambient by pumping air through it from the syringe several times. 6. Press the ‘Enter’ key to bring you into the Accuracy Check screen and follow the on­screen

instructions.

7. The Accuracy Check result is shown in % in the top right corner of the screen. If it is reproducible and within 3% a green tick pass icon will be shown and pressing the Enter key will return you to the main Configuration menu and the Accuracy pass is recorded. 8. In the unlikely event the Accuracy Check result is outside 3% the error icon will be shown and pressing the enter key proceeds to the Calibration Update routine to update the Calibration. 9. The Calibration Update screen will show the volume (L) on the top left corner of the screen, next to the number of strokes. 10. The procedure is the same as for the Accuracy Check. If two of the stokes are within 3% of the reference volume pressing the Enter key will return you to the Configuration menu and the Calibration factor is not updated and a pass is recorded. If outside 3% the error icon is shown and pressing the Enter key will return you to the Configuration menu, the Calibration factor is updated and the Calibration update is recorded. Note: To exit the Accuracy Check screen without performing a check, press the Enter key again to return to the Configuration Menu screen. The accuracy check will not be logged to the Vitalograph micro memory in this case. When to check accuracy ­ 1. In accordance with your own established procedures 2. After annual maintenance checks 3. After cleaning or disassembling spirometer for any reason 4. After adjusting calibration 5. If the flowhead or device has been dropped

7. Cleaning Instructions 7.1. Cleaning and Disinfecting the Vitalograph micro A new mouthpiece (either SafeTway or BVF) should be used for each subject. A delay of at least 5 minutes should be allowed between subjects to allow settling of previously aerosolized particles in the measuring device. It is recommended that the flowhead be regularly cleaned according to the guidelines of the user's facility. In the event of visible contamination of the flowhead it should be cleaned or disinfected as described in the accompanying table. The frequency of cleaning and disinfecting is dependent on the Facility's Risk Assessment, usage, and test environment, but it should be at least monthly or every 100 subjects (500 blows). It is recommended that the flowhead be replaced annually. If a remote flowhead adaptor kit is used, it is recommended that the connection tube be replaced annually.

Disinfect by immersion in sodium dichloroisocyanurate solution at 1000 ppm concentration of free chlorine for 15 minutes.

Note: Always follow the safety guidelines given by the manufacturer of cleaning and disinfectant chemicals. All external parts of the Vitalograph micro require cleaning, i.e. the removal of visible particulate contamination. The parts of the Vitalograph micro that make up the flowhead, which comes into contact with subjects being tested, also require disinfecting. A spirometer is not designed as a ‘sterile' device. Definitions of cleaning and disinfection are as defined in "Sterilization, Disinfection and Cleaning of Medical Equipment: Guidance on Decontamination from the Microbiology Committee to Department of Health Medical Devices Directorate, 1996". Recommendations for chemical disinfectants are derived from the PHLS publication "Chemical Disinfection In Hospitals 1993".

7.2. Disassembling the Fleisch Flowhead 1. Hold the device body firmly in your left hand. 2. Hold the flowhead with your right hand, at the same time press and hold the button firmly on the front of the fleisch flowhead. 3. Slide the flowhead away from the device from left to right. 4. Remove the flowhead cone from the flowhead, by twisting and pulling it away from the flowhead. 5. Clean the flowhead by washing in a mild detergent and removing particulate contamination. To clean the fleisch element, swill vigorously in water with mild detergent or use an ultrasonic bath. Do not attempt to “rubâ€​ or “scrubâ€​ at capillaries. 6. Rinse all parts in clean water. 7. Disinfect by immersion in sodium dichloroisocyanurate (NaDCC) solution at 1,000 ppm concentration of free chlorine for 15 minutes. Prepare disinfectant solution as directed in the manufacturer’s guidelines. file:///H:/Current%20List%20March%202015/Vitalograph/micro%20Model%206300%20User%20Training%20Manual.html

8. Leave to dry completely before reassembling. Drying the fleisch element components may require placing them in a warm place overnight. A drying cabinet is ideal. Note: Always follow the safety guidelines given by the manufacturer of cleaning and disinfectant chemicals.

7.3. Reassembling the Fleisch Flowhead 1. Examine the fleisch element to ensure that no liquid or particles remain in the holes, grooves or pressure tappings. 2. Examine the rubber grommets at the top of the device to ensure no liquids or particles remain in the holes. Also ensure the grommets are not damaged. 3. Fit a new flowhead cone to the flowhead. 4. Slide the flowhead into the grooves in the top cover. The Vitalograph logo and button on the flowhead should be on the same face as the LCD when assembled. 5. It is recommended that an accuracy check is carried out following reassembly to verify correct operation and accuracy. Note: If replacement parts are required, a list of spares, consumables and accessories may be found in section 10 and ordered using the contact details on page 2 of this User Training Manual.
