Device Story

Pulmonary function testing system (EasyOne Pro/LAB) performs spirometry, single-breath CO diffusion (DLCO), and nitrogen multiple-breath washout (MBW). Inputs: patient-exhaled air flow via ultrasonic flow sensor; gas concentrations via molar mass sensor (He/N2) and infrared CO/CO2 sensors; environmental data via temperature/humidity sensors. System uses single-patient use accessories (Spirette, Barriettes) to prevent cross-contamination. Operated by physicians, respiratory therapists, or nurses in clinical/hospital settings. Device processes sensor data to calculate lung function parameters (e.g., FVC, FEV1, DLCO, FRC, LCI). Output displayed on capacitive touch screen for clinician review to support diagnosis and management of respiratory conditions. System supports standalone or networked operation.

Clinical Evidence

Bench testing and human testing confirmed compliance with American Thoracic Society (ATS) recommendations for accuracy and precision for spirometry, DLCO, and MBW tests. Biocompatibility evaluated per ISO 10993-1. Electrical safety and EMC testing performed per IEC 60601-1 and IEC 60601-1-2.

## Predicate Device

Primary Predicate: EasyOne Pro Respiratory Analysis System, model EasyOne Pro K091428 Secondary Predicate:

EasyOne Pro Respiratory Analysis System, model EasyOne Pro LAB K120635

## Device Description

The EasyOne Pro Respiratory Analysis System consists of two different device models: EasyOne Pro and EasyOne Pro LAB.

The EasyOne Pro Respiratory Analysis System devices are pulmonary function testing devices. Both EasyOne Pro Respiratory Analysis System device models provide Spirometry and Single Breath CO Diffusion (DLCO) tests including Lung Volume Parameters. The device model EasyOne Pro LAB additionally provides the Nitrogen Multiple Breath Washout (MBW) method. The

{4}------------------------------------------------

EasyOne Pro Respiratory Analysis System devices meet the ATS recommendations for accuracy and precision for Spirometry, DLCO and MBW tests.

The EasyOne Pro Respiratory Analysis System devices can be used as a stand-alone system and can be connected to a network.

The EasyOne Pro Respiratory Analysis System devices use the following sensors: An ultrasonic flow sensor to measure flow velocity, volume and molar mass of the gases that the patient inhales and exhales; a molar mass sensor which determines the helium content of the respired air for the DLCO test and the nitrogen concentration for the multiple-breath washout (MBW) test; a CO sensor (EasyOne Pro) or a combined CO/CO₂ sensor (EasyOne Pro LAB) to determine CO and CO2 content in breathing gas; a temperature and humidity sensor to collect environmental data.

The EasyOne Pro Respiratory Analysis System devices are used in combination with test gases (DLCO gas for DLCO tests and O2 for MBW tests).

The EasyOne Pro Respiratory Analysis System devices are used in combination with the singlepatient use breathing tube ndd Spirette. For DLCO and MBW tests, the additional single-patient use accessories, the ndd DLCO or FRC Barriettes, are used.

The single-patient use accessories prevent cross-contamination between patients. The Spirette prevents the passage of microorganisms into the inside of the flow sensor; the Barriettes prevent the passage of microorganisms into gas supply tubing.

## Intended Use:

EasyOne Pro/LAB is designed for conducting lung function measurements in general or specialist practices or in hospitals.

EasyOne Pro/LAB can also be used in clinical settings in occupational medicine for performing lung function screenings or measurements.

EasyOne Pro/LAB is used to conduct lung function measurements on adults and children starting at age 4, except measurements of diffusing capacity of the lung based on CO (DLCO), which can be performed on adults and children starting at age 6.

## Comparison of Technological Characteristics:

The modified device models of the EasyOne Pro Respiratory Analysis System have the same technological characteristics with regards to Spirometry, DLCO and MBW testing as the predicate devices.

Side-by-side comparison of technological characteristics

{5}------------------------------------------------

{6}------------------------------------------------

{7}------------------------------------------------

{8}------------------------------------------------

The same single-patient use accessories – Spirette, DLCO Barriette and FRC Barriette – are used with the modified devices than with the predicate devices. The same materials in the patient gas path are used with the modified devices and the predicate devices.

Differences between the modified and the predicate EasyOne Pro Respiratory Analysis System devices:

- • The modified devices differ in appearance from the predicate devices in that they have a different color scheme of the device housing, a different on/off button and a different design of the software user interface.
- A capacitive touch screen is used for the modified devices in comparison to the resistive touch screen used for the predicate devices.
- A different PC-board but providing the same functionalities is used for the modified devices.
- In the modified devices, a metal box around the CO or CO/CO₂ sensor provides improved EMC protection.
- . A power supply of higher efficiency but identical environmental specifications is used for the modified devices.
- An internal USB stick instead of a CF card for internal back-up data storage is used for the modified devices.
- . DISS gas hose connectors are used in the modified devices instead of the Quick Connectors used in the predicate devices.
- • The board used for data acquisition is modified compared to the predicate device, but keeping the same functions.
- • The outer geometry of the MMss sensor is modified compared to the predicate devices, but without modifying the operating principle and functionality of the sensor.
- . For the modified EasyOne Pro LAB device model, a modified combined CO/CO2 sensor is used; the modified combined CO/CO₂ sensor contains an additional reference path but has the same performance specifications as the combined CO/CO2 sensor used in the predicate device.
- The modified devices use Windows 8 instead of Windows XP embedded operating system and SQLite/Microsoft SQL server as database technology instead of Microsoft Access.
- . For the modified devices, some of the labelled specifications were updated to reflect the technical capabilities. No changes were made to the components the specifications relate to.

Design verification and validation demonstrated that the performance of the modified EasyOne Pro Respiratory Analysis System is the same as for the predicate EasyOne Pro Respiratory Analysis System. The modified as well as the predicate EasyOne Pro Respiratory Analysis System meet the ATS recommendations for accuracy and precision for spirometry, DLCO and MBW tests. The modified EasyOne Pro Respiratory Analysis System is therefore substantially equivalent to the predicate EasyOne Pro Respiratory Analysis System.

## Summary of Testing:

Simulated Spirometry, DLCO and MBW testing, as well as testing with humans, confirmed that the modified EasyOne Pro Respiratory Analysis System devices meet the recommendations for accuracy and precision for Spirometry, DLCO and MBW tests of the American Thoracic Society (ATS).

The modified devices were tested to demonstrate conformance with the requirements for medical electrical equipment basic safety and essential performance of standards IEC 60601-1 and IEC 60601-1-2.

{9}------------------------------------------------

Software verification and validation in accordance with IEC 62304 confirmed that the modified EasyOne Pro Respiratory Analysis System meets the specified criteria.

Biocompatibility was evaluated in accordance with ISO 10993-1: Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing within a Risk Management Process.

#### Conclusion:

Based on the above, ndd Medical Technologies concluded that the modified EasyOne Pro Respiratory Analysis System is substantially equivalent to the legally marketed predicate devices and is as safe and as effective for their intended use.
