Hello, hope you are well - is this a free enquiry service? I made a mistake and didn't put a factor 90% for an Asian candidate using this spirometer, but did put his ethnicity. Please do you know if I can still interpret the spirometry test by altering the factor post testing, having a result that is not accurate because I have not properly added the right factor? I have either way told the candidate to return in 1-2 weeks. thank you for your advice. I am washing the transducer with soap and water x1 per week is sufficient, even if restrictive disorders might be due to active TB for example. I work in West London. Many thanks, I am hoping that I can continue as I am doing so I do not have to use the plastic filtered mouthpieces or other disinfectant agent thanks again.

    MicroLab Operating manual Introduction , English The MicroLab is mains/battery operated portable spirometer with the unique combination of ease of use and sophistication. Ease of use is assured through the use of context sensitive help screens, accessed at a touch of a button, that explain every MicroLab feature. The MicroLab uses the CareFusion Digital Volume Transducer, an extremely stable form of volume transducer, which measures expired air directly at B.T.P.S (Body Temperature and Pressure with...
  • Page 4 When the unit is turned on for the first time the system customise menu is displayed. Touch the name of the required region with the stylus stored on the left hand side of the unit and then touch ‘Finish’. This will set the regional defaults including language, if available.
  • Page 5: Overview

    Overview The MicroLab uses a touch screen with icons representing each function available. A stylus, housed in the left hand side of the unit, is provided for icon screen activation and an optional mouse is available. Touch the displayed time to adjust time and date.
  • Page 6: Getting Started

    Getting Started When performing a spirometry test the recommended workflow is to enter the patient’s details, or retrieve them from memory, perform the required test and then print and save the results. Please ensure that the turbine transducer is plugged in to either of the first two sockets on the right hand side of the instrument.
  • Page 7 Touch the ‘Patients’ icon to enter the patient database. The required patient may be selected from the stored patient list. If the patient details have not been previously stored then touch Add to enter the new patient’s details. The patient details may also be downloaded from the optional SPCS software.

  • Page 13: Customisation

    Customisation The ‘Customise’ option from the main menu may be used to configure many of the features of your MicroLab and are divided into system and spirometry options. System options allow you to configure the following: Language. Height and weight units. Date format.
  • Page 14: Administration Mode

    Administration Mode Administration mode allows administrator to restrict the availability of functions to the user by disabling icons on the main menu. For example, after the unit has been configured to administrator’s requirements, disabling of the ‘Customise’ icon will prevent any further adjustment by the user.
  • Page 15: Paper Loading

    Paper Loading To load a new roll of thermal paper lift the paper cover using the side levers, place the paper into the compartment as shown and close the cover firmly. It is recommended that only CareFusion thermal printer paper (Cat No. 36;PSA1600) is used with the MicroLab to avoid damage to the thermal printer head.
  • Page 16: External Printing

    External Printing When printing, the MicroLab will default to an external USB printer, if connected. Using the USB cable provided connect the mini A/B socket on the right hand side of the MicroLab to the input socket on the printer. For a list of compatible printers refer to the web site www.carefusion.com/micromedical or contact your local dealer.

The results and graphs produced are displayed directly on the PC screen.
  • Page 18: Cleaning The Transducer

    Cleaning the Transducer The transducer requires no routine maintenance or servicing. However, if you wish to disinfect or clean the transducer it may be removed by means of the following procedure: 1. Rotating the turbine transducer anti;clockwise until the locating pip lines up with the small rectangular cut;out in the housing as shown below.
  • Page 19: Servicing

    Servicing There is no routine maintenance required for the MicroLab and there are no user serviceable parts in this instrument. Please return the unit to CareFusion or an authorised agent if servicing is required. Troubleshooting In the unlikely event that the display ‘freezes’ and the unit does not respond to any key presses, hold the on/off button down for 10 seconds until the unit switches off and then turn on again.
