Carefusion SpiroUSB Spirometer device set-up, software installation and troubleshooting guide

Carefusion SpiroUSB Device Setup

The Carefusion SpiroUSB comes with two boxes.

The first of which contains the physical product and accompanying accessories. These include an e-manual on the orange USB, 6 single-use cardboard mouthpieces, USB cable and various instruction manuals and validation certificates. 

The second box will contain the software required for the device to communicate with a Windows PC. It comes with a Vyaire CD Software suite and a smaller box which contains a Software License Key on a USB.

DO NOT LOSE THIS. Your software will not function otherwise.
Do not try to copy-paste any data off of the USB, it is not designed for storage. 

There isn't a Mac version available, although you can use Boot Camp, VMware or Parallels for example as a work around with Mac Computers. 

First thing you may ask is what is this thing? I did too. It serves simply as a stand on which you can place the SpiroUSB.

The other (working) portion of the SpiroUSB has a cable attached to it with a USB connection. Plug this into your USB socket in order to power on the SpiroUSB. No batteries are required! 

If your device is working correctly, you should see a blue light appear above the mouthpiece insertion which is characterised by the honeycomb grill. 

Do not breathe directly into this mouthpiece. Use the Microgard IIb filters or one-way mouth-pieces that can be purchased here.

Carefusion SpiroUSB Software Setup

On this disc, you can find the Carefusion SpiroUSB Software for PC. Yes, I know - it's almost 2020 and we're using CDs. We recommend copy and pasting the files from the CD onto a USB in order to future proof your clinic for backward and forward device compatibility. If you really don't have a device with a disc reader or you're not too sure how to move the software off the disc, we've done it for you here. 

Click this link to download the Carefusion SpiroUSB Software  (105mb).

On the back of the case, you will find a 9 digit serial number needed to install the SpiroUSB software. Probably a good idea to take a photo of this and store it somewhere safe. See the right-most photo for an idea of where you will find your code. 

Now to the nitty-gritty.

I will be using a Windows Surface book, running Windows 10.

Step 1.

Run the "Spirometry PC Software - InstallShield Wizard".

Step 2.

Accept the terms & conditions to proceed with the installation.

Step 3.

Once you reach this serial page, you'll need to find that 9 digit number I mentioned earlier. (on the back of the Vyaire software case). Fill in the details for User Name, Company Name and the Serial number. You can choose who has access to this software from the two options at the bottom of the window. 

Step 4.

If you've made it this far, your installation is probably complete. The only road bump you might have had thus far would involve the 9-digit serial key or computer storage space. If it wasn't the former, delete some stuff off your computer and try again. 

You can start up your program now. The icon is a Monitor and the SpiroUSB. 

Carefusion PC Software Homepage • Sentinel Hardware Key 

After starting the software you should find yourself on this homepage.

If you haven't inserted your Sentinel USB Hardware Key into your computer - the Carefusion page will immediately display this warning. (Status code 226 or 206).

Plug-In the Sentinel USB key and the warning should go away. The USB key will have a green light displaying if the device is working correctly. 

But wait! My USB light isn't on? My warning also didn't go away? 

If this is the case, then we're going to need to install a driver for the Sentinel key.

Download Sentinel Key Driver (405mb filesize).

Click on the link above to download the Sentinel Key Driver for PC. The file contains several other programs for the sentinel key, however, we only require one program - feel free to delete the file after installation.

The file will contain StartHere.exe • "Windows" Folder • StartHere.exe.manifest • autorun.inf 

Use these next images to guide you through the installation pathway. 

Carefusion Software Usage

Once the Sentinel Key Driver has been installed, restart your computer in order to ensure the computer successfully implements the installation. 

After the PC has restarted, plug in your Sentinel Key and start the Carefusion Program again. You will notice the Status 226 / 206 notice has disappeared. 

If your Carefusion software is out of date, there will be a notice on the upper right corner of the screen prompting you to update. This is recommended for proper device function.

Clicking the installation prompts and following its instructions will bring up the installation wizard once more. 

Once updating is complete. Your Carefusion software is finally ready to go. The next few images will show you various software options and capabilities. I suggest having a play around with the software and using the e-manual (orange usb).
