The SpiroUSB is a PC connected spirometer dedicated to work with
the comprehensive Spirometry PC Software (SPCS).
SPCS is a fully Windows™ compatible spirometry system that
interfaces seamlessly with the SpiroUSB providing many display
options and includes powerful reporting and database facilities.
SPCS has many advanced features including display of real time
respiratory traces, predicted values, patient database, and the
ability to carry out pre and post bronchodilator and post steroid
testing.
The SpiroUSB 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
Saturated water vapour) thus avoiding the inaccuracies of
temperature corrections. This transducer is insensitive to the effects
of condensation and temperature and avoids the need for individual
calibration prior to performing a test.

Installing SPCS
SPCS is supplied on CD ROM with your SpiroUSB. Install SPCS
according to the instructions in the SPCS quick start guide.
Installing SpiroUSB device driver
The driver enables CareFusion Ltd USB devices to work with USB
enabled PC software on Windows based machines.
Compatibility status
There are two versions of the USB driver. The driver used depends
on the Operating System you are using. There is a driver for
Windows 2000/XP Operating Systems.
The following operating systems are supported:
• Windows 2000 Professional service pack 4
• Windows XP Home Edition
• Windows XP Professional
• Windows Vista
The driver will not be supported under Windows 95, Windows 98
Gold (First Edition), Windows 98SE (Second edition), Windows ME
(Millennium edition) or Windows NT 4.0 Workstation, as USB is not
officially supported on these Operating Systems.
Driver installation – Windows 2000/XP/Vista
Windows 2000, Windows XP and Windows Vista support preinstallation of drivers.
If software is installed that provides support for USB, the drivers
may be pre-installed, allowing automatic installation of the drivers
when the device is connected to the USB port. If the device does
not install automatically, follow the steps to install the device
manually.

Operation
Simply connect the SpiroUSB to a spare USB port on your PC with
the supplied SPCS installed. SPCS will automatically detect that the
SpiroUSB has been connected to a USB port and will run, ready for
you to start your spirometry session. There is no need to remove
the SpiroUSB between sessions.
Please note that with certain PC configurations, even if a compatible
operating system is being used, SPCS may not be launched
automatically when the SpiroUSB is plugged in. In this case SPCS
may be run in the usual way using the Windows on-screen Start
button.
The SpiroUSB transducer is supplied with a two-meter cable. If this
length is insufficient then a remote USB hub should be used.
Remote USB hubs are readily available from computer accessory
suppliers. For some recent computers the USB signal will work over
a longer distance using an extension cable. An extension cable has
been supplied for your convenience, if required. If communication
problems are encountered using the extension cable then a remote
USB hub must be used.
Looking after your SpiroUSB Spirometer
Please observe the following precautions:
• Avoid exposing the SpiroUSB to direct sunlight during use.
• Avoid operating the spirometer in dusty conditions or near to
heating appliances or radiators.
• Do not keep the spirometer in a damp place or expose it to
extremes of temperature.
• Do not direct the transducer holder towards a strong light source
whilst operating the spirometer.

Cleaning the Transducer
The transducer requires no routine maintenance or servicing.
However, if you wish to sterilise 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.
2. Gently pull the transducer away from the housing.
3. The transducer may now be immersed in warm soapy water
for routine cleaning or immersed in a cold sterilising solution
e.g. Perasafe for a maximum of 10 minutes (Alcohol and
chloride solutions should be avoided). After
cleaning/sterilising, the transducer should be rinsed briefly in
distilled water and dried. Perasafe is available from CareFusion
in convenient 81g containers, Cat No. 36-ACC1013.
4. Re-assemble the mouthpiece holder.

Caution
• Pulmonary filters are single patient use. If used on more than one
patient there is a risk of cross-infection. Repeat use may increase
air resistance and lead to an incorrect measurement.”
• Mouthpieces are single patient use. If used on more than one
patient there is a risk of cross-infection. Repeat use may degrade
materials and lead to an incorrect measurement.”
