The summary describes a standard spirometer device and software for measuring lung function. There is no mention of AI, ML, or related concepts in the device description, intended use, or performance studies. The software performs calculations based on chosen reference values, which is a standard function and does not indicate AI/ML.
No
The device measures lung function for diagnosis and screening, it does not provide treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device "measures lung air volume and airflow rate for pulmonary disease diagnosis and screening." and provides "information about a patient's pulmonary function which may be compared with normal values or the patient's previous values."
No
The device description explicitly states that the system includes a "Medikro@ spirometer unit" which is a hardware component connected to the PC via USB, and a "SpiroSafe disposable flow transducer" which is also a hardware component. While software is used for processing, the system relies on dedicated hardware for data acquisition.
Based on the provided information, the Medikro® Spirometer is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Medikro® Spirometer Function: The Medikro® Spirometer directly measures physiological parameters (lung air volume and airflow rate) from the patient's body through breathing maneuvers. It does not analyze specimens taken from the body.
- Intended Use: The intended use clearly states it measures lung air volume and airflow rate for pulmonary disease diagnosis and screening. This is a direct physiological measurement, not an analysis of a biological sample.
Therefore, the Medikro® Spirometer falls under the category of a medical device that performs physiological measurements, but it is not an IVD.

Device Description
Medikro® spirometer runs on a personal computer with Microsoft Windows operating systems.
Medikro@ spirometer unit is connected to PC via USB port (USB model). SpiroSafe disposable flow transducer is connected to the spirometer unit via pressure tube. Nose clip is used to prevent air flow from nose during measurements. Optional calibration syringe is used for recommended daily volume calibrations.
Medikro® spirometers are used to measure lung air volume and airflow rate. Medikro® Spirometry Software is used to perform the measurement and calculate the measurement volume based on chosen reference value. The reference value is based on patient's gender, race and age. User can analyze the results in different presentations and create a final report based on the results and patient information. For details about tested reference values see: Tab Software Verification and Validation.
The spirometers take all the power that it needs from the USB port, so no other external or internal power supply is needed.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Nonclinical tests were performed:
- AAMI / ANSI ES 60601-1:2005/(R)2012 and A1:2012, C1:2009/(R)2012 and . A2:2010/(R)2012 (Consolidated Text) Medical electrical equipment - Part 1: General requirements for basic safety and essential performance (IEC 60601-1:2005, MOD).
- IEC 60601-1-2 Edition 3:2007-03, Medical electrical equipment Part 1-2: General requirements for basic safety and essential performance - Collateral standard: Electromagnetic compatibility - Requirements and tests.
Conclusion for Nonclinical tests:
Medikro spirometers M913 Medikro® Nano, M914 Medikro@ Primo and M915 Medikro® Pro are all tested according AAMI / ANSI ES 60601-1:2005 standard. Testing was performed at CSA group CB testing laboratory. Based on test results Medikro spirometers M913 Medikro® Nano, M914 Medikro® Primo and M915 Medikro® Pro were found to comply with AAMI / ANSI ES 60601-1:2005 standard.
IEC 60601-1-2 EMC testing was made to M915 Medikro® Pro, M913 Medikro® Nano and M911 Medikro® Ambi. EMC testing was made according to IEC 60601-1-2 requirements and includes both emissions and immunity testing. Testing was performed at Savonia Polytechnic EMC laboratory by the laboratory test engineer. Full test reports were made for M915 Medikro® Pro, M913 Medikro® Nano and M911 Medikro® Ambi. Difference between M915 Medikro@ Pro and M914 Medikro@ Primo is the external casing and that Primo does not measure ambient conditions (same circuit board, but these components are left out).
American Thoracic Society (ATS) 24 standard waveforms test was made for all spirometer units (M915 Medikro® Pro, M914 Medikro® Primo and M913 Medikro® Nano) and all units meet the recommendations for:
- . Measuring FVC
- Measuring FEVI .
- . Measuring FEF25-75%
- Measuring PEF .
- . Measuring MVV
- Resistance to flow .
Testing was done for the Medikro Oy measurement devices against recommendations published by the American Thoracic Society. The essential performance criteria's for spirometers is well defined by the ATS. Spirometers meeting ATS criteria for essential performance are substantially equal. The predicate devices are also designed to meet these ATS criteria.
ISO 26782 test was made for all spirometer units (M915 Medikro® Pro, M914 Medikro® Primo and M913 Medikro® Nano) and all units meet the ISO 26782 requirements for: - Measuring FVC accuracy and repeatability .
- Measuring FEV 1 accuracy and repeatability .
- Measuring FEV6 accuracy and repeatability
- Linearity .
- lmpedance .
Testing was done for the Medikro Oy measuring devices Medikro Spirometer models Nano, Primo and Pro against recommendations published in the ISO 26782 standard.
Based on these results Medikro spirometers M913 Medikro® Nano, M914 Medikro® Primo and M915 Medikro® Pro are substantially equivalent to the predicate devices. Any differences between the subject and predicate devices do not raise any new questions of safety and effectiveness.
