Application Notes
Data Backup Deletion and Restoration in EasyOne Air
ndd offers a file-based integration utilizing an SFTP or network-based location for file communication with an EHR vendor. HL7 is the standard data structure that ndd utilizes but can support other data formats as well. The use of other interface engines can be utilized to complete an integration project.
How long does the integration process typically take?
Duration depends on the IT team of the facility. The ndd side of the integration process can be completed within a few hours for standard integrations. EasyOne Connect software is simply configured to point to the SFTP or network-based location where files are being placed.
How does ndd ensure that data is securely transferred during integration?
EasyOne Connect software utilizes AES 256 encryption. SFTP has its own security protocols built into it. If a network-based location is utilized, it will follow the protocols of the facility.
Can patient data and test results be accessed across multiple laptops and desktops within a clinic?
Yes, EasyOne Connect offers an optional centralized patient database feature, enabling seamless access to patient orders and results across all instances of the software, irrespective of physical location. Customers can leverage their on-premise SQL servers or MS Azure environments to ensure data accessibility and consistency.
Does ndd offer user management within the software?
EasyOne Connect provides flexible options for managing users and their access. User accounts can be created and managed directly within EasyOne Connect for simple permission control. For more advanced management, the software supports integration with Active Directory for using your existing directory service accounts, groups, and permissions. EasyOne Connect also supports optional single sign-on (SSO) capability. If you would like to review the Active Directory Application Note, please contact [email protected].
Can ndd provide examples of successful integration with other clients?
ndd has integrated with all major vendors and can provide examples of successful integrations with various healthcare providers and organizations. You can contact our integration department via email at [email protected] for more information.
How does ndd handle updates and maintenance to the integration?
ndd does not handle the maintenance and upgrades as the software is installed locally on the client’s machine. We do, however, offer a silent installer package that our support team can assist you with. This silent installer can be executed via a script through active directory commands depending on your facility. It is the responsibility of the facility to implement any future updates. There is no licensing fee associated with the software and/or the updates.
Are there any additional costs associated with integration?
ndd does not charge for standard integration. In the event custom development is needed, ndd will provide a statement of work before a project begins. Almost all EHR vendors will charge a fee that the client is responsible for.
The result HL7 message will consist of a combination of discrete results and an embedded base64 PDF attachment for the PFT report. If you prefer, we also offer the option of including a reference link instead of the embedded PDF.
What kind of support does ndd offer during and after the integration process?
You can schedule a meeting with an integration engineer from 8 a.m. to 5 p.m. ET Monday through Friday. ndd can accommodate meetings outside of that timeframe if planned accordingly. The integration team can be reached via email at [email protected]. The support team can also be reached via email at [email protected] or by phone at (978) 470-0923.
You can find the product specification on the respective product pages. The specification contains a list of all supported normal values.
To get more detailed information about the supported parameters, age range, ethnicities and height range of each supported predicted set, please click here.
BTPS Correction is used to convert flow and volume measured at ambient conditions to the conditions within the lungs. Ambient conditions are called ATP (ambient temperature, pressure); the conditions within the lungs are called BTPS (body temperature, pressure, water vapor saturated).
All our products can be purchased through our authorized distribution partners. Please contact us to receive more information on finding your local dealer.
What are my options for printing results from the EasyOne Air?
A compatible printer can be connected directly to the cradle provided with the device. Please consult our Printer Compatibility List including thermal printer options.

How many tests can be saved in the device's memory?
The on-board memory for the EasyOne Air spirometer can store approximately 10,000 tests. For long-term storage the data can be synchronized to the EasyOne Connect PC software database.
The EasyOne Air spirometer uses a rechargeable lithium-ion battery. An empty battery can be fully charged in about 5 hours. A fully-charged battery can support the performance of approximately 100 spirometry test sessions. While the battery life is highly dependent on the intensity of use, ndd generally recommends that the battery be replaced every 3 years to ensure the best user experience.
Do I need to calibrate the EasyOne Air spirometer?
No. All EasyOne products are designed to not require calibration. ndd’s patented TrueFlow technology is the only technology proven to remain stable over its lifetime. A number of independent papers have been published that confirm this long-term stability.
For organizations like NIOSH/OSHA or Social Security/Disability, where calibration checks are required, ndd offers a 3-Liter calibration syringe. A calibration check (cal-check) is not to be confused with calibration. A cal-check simply validates that the device is within calibration limits. Unlike calibration, a cal-check does not adjust the calibration values.

Which print options do I have with the EasyOne Air device
You can also synchronize the test to your EasyOne Connect on the PC and print from there.
We will not discuss this option here, we will focus on the options when using the standalone device
The print options need to be selected in the EasyOne Air menu first. This is how to do it.
From the main menu, go to Tools > Settings > Print and select the Print format. In this view you can set up all printer related settings.
Let’s start with the most common option, which is external printing (Option 1). This involves a direct connection from the cradle to a printer.
Ensure to connect the micro USB end of cable to the correct port on the cradle and connect the USB type B end to the printer.
There is a large choice of printers on the market, each supporting different print formats or languages. In order to print successfully, the printer must support at least one of these formats. Direct PDF, HP PCL 3 Enhanced protocol, HP PCL3GUI
Another popular way to print results is via the integrated PDF printer (Option 2). This will create a PDF file in the EasyOne Air storage so that it can be moved to your PC and further utilized.
Whenever you print a test result, the file will be stored in the Exchange drive.
To access this file, connect the device to a PC via the USB cradle. Usually a pop up window opens displaying the Exchange drive. If no pop up window appears, try opening the Exchange drive manually. For example, navigate in the Windows Explorer to this PC, then select EasyOne Air, then Exchange and select the desired PDF print out.
The Exchange drive is the EasyOne Air internal storage and has only 15 MB of storage space. In there you find all PDF prints and also the log file.
The third method is to print the results via thermal printer (Option 3).
This method requires a special thermal printer that is compatible with the EasyOne Air.
Once the printer is connected, the results can be printed out immediately.
