FAQ

ndd can integrate with any EHR vendor that can support a bi-directional HL7 orders/results lab interface.

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.

The first step for an integration project is to complete the EMR integration request form here: https://nddmed.com/f/emr. An integration specialist will then reach out to you with the next steps.

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.

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.

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.

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].

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.

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.

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.

HL7 specifications can be found here.

1. Local SQLite file-based database.
2. On-premise Microsoft SQL Server database.
3. Azure cloud-hosted Microsoft SQL Server database.

Please see the application note for additional information.

The facility is responsible for setting up and hosting either option. ndd requires a username and password if using an SFTP environment.

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.

No, a server is not required.

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.

The EasyOne Pro LAB is exactly the same as the EasyOne Pro, except that it has the capability to perform the multi-breath washout (MBW) test. This test requires additional sensors and the use of 100% Oxygen.

The Spirette mouthpieces are single-use only and disposable.

To avoid cross contamination the Spirette mouthpiece is recommended to be used only once. Washing / disinfection of the Spirette mouthpiece might damage sensitive parts, which may compromise the test results and the safe avoidance of cross contamination.

As a crucial component of the TrueFlow technology, the measurement accuracy is also ensured by the ndd Spirettes/EasyOne FlowTubes, which are precision-manufactured and undergo stringent quality inspections. Therefore we highly recommend using the original ndd Spirette/EasyOne FlowTube to fully benefit from the TrueFlow technology.

To add a filter (2) to the EasyOne Pro, insert the (1) Spirette FA Pro/LAB into the EasyOne Pro handle. Then attach the filter to the Spirette FA Pro/LAB, as shown in the diagram below. If you have questions about how to connect or use ndd filters, please contact ndd customer support in North America at [email protected] and internationally at [email protected].

This error is usually a communication error shown while printing. It means something wasn’t quite ready. Typically, it is best to clear the error by hitting 1 then 3 then 5 on the keypad and to try again. Most Self-Test errors can be cleared and investigated with the code 1-3-5.

All EasyOne products are designed to require no calibration and minimal maintenance. The device is designed to remain in calibration throughout its lifetime. No calibration procedures are required prior to testing. Our TrueFlow ultrasonic technology assures accurate volume and flow measurements every time. And our unique automated TrueCheck process assures that all gas measurements are accurate for each test. You may choose to use the optional 3-liter calibration syringe to verify volume and flow accuracy, as recommended by ATS/ERS.

A PFT session including spirometry and DLCO generally takes less than 20 minutes.

The EasyOne Pro/LAB is compatible with virtually all PC-style USB printers, without the need for external driver installation. The printer can be connected directly to a USB port on the rear of the device. We can sell you a printer with the device, or you can supply your own.

You can also connect the device to your network where it will automatically find any connected, compatible printers avoiding the need for a dedicated printer for your PFTs.

Spirette: Each test performed requires the use of a spirette. This is a single-patient-use mouthpiece which ensures that no contamination can reach the internal flow path of the device. This means that no cleaning is required between patients, and no calibration, ever. Simply toss the spirette after each test session.

Barriette: For a DLCO test, in addition to the spirette, you will need to use a barriette. This protects the valve and hose system from contamination, eliminating the need for cleaning between patients.

FRC barriette: This is similar to the DLCO barriette, but used only when performing a multi-breath washout test.

Gasses: The DLCO test requires a standard medical grade DLCO gas mixture consisting of 0.3% Carbon Monoxide, 10% Helium, 21% Oxygen, remainder Nitrogen. The multi-breath washout test requires 100% Oxygen. These gasses are readily available from your local medical gas supplier in various tank sizes. We will assist you in selecting the appropriate tank regulators required for connection to the device.

The device itself is self-contained and measures only 270 x 335 x 270 mm (10.6 x 13.2 x 10.6 inches) (h x w x d). No additional PC, monitor, keyboard or control unit is required. This allows it to easily fit on a counter. You will also need to allow for storage of the gas tank(s) which come in a variety of sizes, and can usually fit comfortably in a corner, or under the counter.

The EasyOne Pro/LAB is designed to require minimal maintenance. The annual replacement of four external components is ALL that is required to keep the system running smoothly. These components are available as a convenient kit. Installation is done in minutes and requires no special tools.

If you are missing parameter data or a report seems incomplete, it might be due to your printer’s ink supplies. Try setting the spirometer to HP BW in the Configuration and Report Settings. If the color ink was causing the problem, this should solve it. If it was the black ink, you will get a completely blank page.

The EasyOne only works with a limited set of printers because it uses specific, aging Print Command Languages. Please check to see if your printer is on the Printer Compatibility List. If your printer is listed but the spirometer still won’t work, verify that the printer is not in error mode and check all points of connection with the EasyOne.

There are a few points that can be checked and improved. The EasyOne uses two AA batteries and, when these get low, communication may falter. Fresh batteries are best. Also, the 9-pin contacts on the bottom of the EasyOne and Cradle may oxidize. Polish these with an alcohol swab to clean them. Finally, the USB ports may be damaged. Check the cradle and printer or computer for signs of wear and try a new USB cord. The EasyOne uses a common type A/B USB cord.

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.

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.

The typical spirometry exam is a three-phased process – each with their own coaching techniques to help patients produce an effective test.

1. Phase 1
   In the first phase, the goal is to instruct the patient on the proper techniques to apply their mouth to the spirometry mouthpiece. Best results are achieved when the patient takes a deep, deep breath, placing the mouthpiece between their teeth, and sealing the mouthpiece with their lips.
2. Phase 2
   The second phase is the BLAST. This is when the patient will blow out as hard and as fast as possible. Coaching a patient in this phase is best achieved by developing a rapport with them prior to the exam, as the tester will learn which level of coaching is best for that individual patient.
3. Phase 3
   The final phase is the remaining 5 to 6 seconds of exhalation. In this phase, you’ll quietly encourage the patient to “keep blowing” to complete the exhalation.

Each time a test is started, the baseline is set. The software will prompt you to block the Spirette for this step so there is no airflow. Passing the baseline setting is required before the test can start. If the baseline fails, there may be an error stating:

“baseline setting failed” “Check Spirette insertion” “Device initialization failed”

Here are a few steps to try when the baseline setting error occurs.

• First, ensure the Spirette is blocked and fully inserted.
• Open the Spirette wrapper halfway from the bottom, leaving the top part wrapped.
• Insert the Spirette fully align the arrows.
• Push the Spirette in until there are no gaps.
• Avoid any airflow, including vents, fans, or windows.
• The end of the Spirette can also be blocked by a hand.
• If the error still occurs, try changing the Spirette out with a new one.

If the error still occurs after changing the Spirette, try to reset the amplitude.

Resetting the amplitude on the device may resolve the baseline setting errors.

To reset the amplitude, follow these steps:

• Start a test and attempt to set the baseline.
• When the baseline setting fail error appears, remove the Spirette and reinsert it at a 90° rotation. Intentionally incorrect.
• Click Retry. There will be another error.
• Insert the Spirette correctly again and restart the test to check if that resolved the error.

These steps may need to be attempted a few times.

There are multiple patient-symptoms or medical conditions that justify the use of spirometry. A few of the most common indicators include:

• To manage asthma and COPD patients
• Evaluate shortness of breath
• Perform surveillance for occupational-related lung disease
• Evaluate former or current smokers over the age of 45 for COPD
• Classification of COPD. (COPD is an umbrella term that covers multiple respiratory diseases including chronic bronchitis, emphysema, and idiopathic pulmonary fibrosis (IPF))
• Monitor disease progression
• Measure response and progress due to treatment, medication, and respiratory therapy
• Smoking cessation

A complete pulmonary function test is a comprehensive assessment of lung function that includes three key components: spirometry (possibly pre/post bronchodilator), lung volume measurements, and diffusing capacity for carbon monoxide (DLCO).

Together, these tests provide a full picture of how well the lungs are ventilating (moving air), how much air they can hold, and how efficiently they transfer gases like oxygen into the bloodstream.

Explore how ndd’s EasyOne solutions bring accuracy and ease to every step of pulmonary function testing.

A pulmonary function test (PFTs)are a group of noninvasive tests that monitor the performance of the lungs. They measure lung volume, capacity, rates of flow, and gas exchange.

Adding the following: PFTs typically include several different types of tests:

• Spirometry, which measures how much air you can breathe in and out and how quickly you can exhale.
• Lung volume measurement, which determines the total amount of air the lungs can hold.
• Diffusion capacity test (DLCO), which evaluates how efficiently gases like oxygen move from the lungs into the blood.

Together, these tests provide a comprehensive picture of lung function and can be used to monitor lung performance over time or assess the impact of environmental or occupational exposures.

Diffusion capacity (DLCO) is a clinically useful test that provides a quantitative measure of gas transfer from the lungs to the blood. It complements spirometry in evaluating and managing patients with cardiac and/or respiratory disease.

Why DLCO is important in lung disease diagnosis and management:

• Helps differentiate between obstructive and restrictive lung patterns.
• Detects early changes in gas exchange, even when spirometry appears normal.
• Assists in evaluating interstitial lung diseases, such as pulmonary fibrosis.
• Useful for monitoring disease progression or response to treatment.

FEV stands for Forced Expiratory Volume. The FEV1 parameter equates to the volume that is exhaled after one second. It is intended to measure the severity of an obstruction – with average FEV1 results measuring two to four liters. A lower FEV1 result equates to higher obstruction.

FVC stands for Forced Vital Capacity. FVC determines the total exhaled volume of air. FVC tells the spirometry tester how much air volume the patient can exhale. The FVC will fall when the patient can’t inhale deeply or can’t exhale completely. The average FVC result for an elderly man is about four liters (one gallon) of air. The intent of this parameter is to detect restriction.

Spirometry is used to diagnose and monitor lung diseases, assess pulmonary function, and support occupational health screenings. Spirometry helps healthcare providers to:

• Diagnose respiratory conditions like COPD and asthma
• Monitor disease progression and treatment effectiveness in patients with chronic lung conditions
• Evaluate lung function in workplace health programs, particularly for individuals exposed to dust, chemicals, or other respiratory hazards

By using a diagnostic spirometer, medical professionals can detect lung diseases early, track changes over time, and ensure workplace safety.

Spirometry is the primary method of assessing overall lung function. It works by measuring the volume of air that a patient can forcefully expel from the lungs after inhaling as much as possible. This non-invasive test is completed by medical professionals and is essential for diagnosing and monitoring respiratory conditions like COPD, asthma, and other lung diseases.

Using a diagnostic spirometer, a trained healthcare professional can assess lung health, detect early signs of disease, and guide treatment decisions.

A spirometry test is a specific type of pulmonary function test. Spirometry measures the lungs volume (or how much) and flow (how quickly) the patient can move air into and out of their lungs. Spirometry will tell the tester if the patient has an obstruction, restriction, a mixed defect, or has normal lung flow.

Spirometry does NOT look at gas exchange and does not provide absolute lung volumes (RV, FRC, and TLC).

Diffusion capacity or transfer factor of the lung for carbon monoxide (CO) is known as a DLCO test. This measures the gas exchange and is used in conjunction with spirometry to provide a differential diagnosis. DLCO is also used to assess disease severity and is one of the best correlates of emphysema in COPD.

The final component that completes the full PFT exam is measuring absolute lung volume (RV, FRC, and TLC). This is completed by measuring body plethysmography, gas dilution, or nitrogen washout. Lung volumes are commonly used for the diagnosis of restriction. In obstructive lung disease, they are used to assess for hyperinflation. The changes in lung volumes can also be seen in a number of other clinical conditions.

The FEV1/FVC ratio is typically expressed as a percentage (such as 75%). Nearly three-fourths of lung volume can normally be exhaled during the first second of the spirometry test. As such, the normal ratio falls between 65 to 85 percent. The range of normal FEV1/FVC ratio is determined by the patient’s age.

A simple guide to reading spirometry test results.

Lung volumes are used to diagnose restrictive lung disease and to assess for hyperinflation in obstructive lung disease. With restrictive lung disease, TLC, VC, and RV may be decreased due to the inability of the lungs to expand properly.

The lungs are restricted from fully expanding and filling with air. In an obstructive disease such as COPD, patients may develop hyperinflation, which will result in a higher than normal TLC and RV. Conversely, IC will be decreased due to air trapping in the lungs.

Lung volume testing with the EasyOne Pro LAB provides fast, accurate, and fully automated measurements without the need for a body box. Its compact design and TrueFlow and TrueCheck technologies ensure reliable results for comprehensive lung assessment in most clinical settings.

Diffusion capacity testing (DLCO) is best used to pinpoint the type of respiratory disease. It is completed after spirometry when an obstruction or lung volume issues are predetermined.

• Differentiating emphysema from obstructive bronchitis and chronic asthma
• Assessment of COPD
• Detection of pulmonary vascular disease
• Assessment of shortness of breath (SOB)
• Disability/Impairment evaluations for ILD or COPD

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
• A compatible printer list can be found on the ndd website.

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.
