No
The document describes a standard spirometer that measures airflow using an ultrasonic sensor and transmits data wirelessly. There is no mention of AI, ML, or any algorithms that would suggest learning or adaptive capabilities. The functions described are data acquisition, communication, and visualization.
No
The device is described as being intended "to conduct diagnostic spirometry testing," which means it is used to diagnose conditions, not to treat them.
Yes
The "Intended Use / Indications for Use" section explicitly states that "The EasyOne Sky spirometer is intended to conduct diagnostic spirometry testing".
No
The device description explicitly states it consists of hardware components (TrueFlow Sensor FT, EasyOne FlowTube) in addition to the software application.
Based on the provided information, the EasyOne Sky spirometer is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body. The EasyOne Sky spirometer measures airflow directly from the patient's breath. It does not analyze blood, urine, tissue, or any other bodily fluid or sample.
- The intended use and device description clearly indicate direct patient measurement. The device measures air flow during breathing maneuvers performed by the patient.
- The device description focuses on measuring physical parameters (airflow) rather than analyzing biological or chemical components of a sample.
Therefore, the EasyOne Sky spirometer falls under the category of a medical device used for diagnostic purposes, but not specifically an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The EasyOne Sky spirometer is intended to conduct diagnostic spirometry testing on adults and pediatric patients starting at age 4.
The EasyOne Sky spirometer is used by general practitioners, specialists and healthcare professionals.
The EasyOne Sky is used in hospitals, clinical settings, and in occupational medicine.

Device Description
The product EasyOne Sky (EOS) is a medical electrical equipment for spirometry testing. It consists of the hand-held TrueFlow Sensor FT (SeNe) comprising an ultrasonic flow sensor that conducts air flow measurements, the application EasyOne Mobile (EOMA), and the breathing mouthpiece EasyOne FlowTube (EOFT). The EOS can be used with the optional accessories EasyOne Filter FT and a nose clip.
Key functions:
- . The key function of the TrueFlow Sensor FT (SeNe) is to acquire patient flow data by measuring transit-times of ultrasonic pulses and to send data wireless (via Bluetooth Low Energy) to the host system. The measurements and data transmission are performed by the firmware of the SeNe defined as MDSW with clinical functions.
- . The key function of the application EasyOne Mobile (EOMA) is to trigger the start of the measurement with the TrueFlow Sensor FT, to communicate with it and to visualize the data received from it.
- . The EasyOne FlowTube (EOFT) is an individually packaged, single-patient-use breathing tube and is intended to canalize patient breath through the flow sensor tube. The EOFT is an essential accessory to EOS.
The host system, for example a smartphone, where EOMA runs on, is not part of the EOS medical electrical equipment.

Dear Andreas Senn:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

The subject device EasyOne Sky has similar intended use, target populations, technological characteristics, and materials as the predicate device EasyOne Air and reference device GoSpiro. The subject and the predicate device have the same fundamental design, use the same TrueFlow ultrasound measurement principle to and same EasyOne FlowTube breathing mouthpiece and optional EasyOne Filter FT accessories. The spirometer itself is reusable whereby accessories are single use devices and intended for single patient use only.
EasyOne Sky, EasyOne Air and GoSpiro spirometers all provide basic spirometry testing in accordance with ATS / ERS recommendations and guidelines.
The hand-held sensors TrueFlow Sensor FT and GoSpiro do not have a built-in display, they all require a separate device for displaying results. The EasyOne Sky and the GoSpiro are using an application for displaying data or graphics.
Any differences between EasyOne Sky and the predicate EasyOne Air do not raise questions concerning safety and effectiveness. Performance testing in accordance with applicable standards demonstrates that the EasyOne Sky is adequate for its intended use. The EasyOne Sky spirometer is therefore substantially equivalent to the predicate.

SUMMARY OF NON-CLINICAL TESTS
12
CONCLUSION
The subject device EasyOne Sky has similar indications, intended use, target populations, technological characteristics, and materials as the predicate devices. Non-clinical testing demonstrated that the proposed device is at least as safe and effective as the predicate. Therefore the subject device is substantially equivalent to the predicate device.
