The description details standard spirometry measurements, data digitization, and software for data management and reporting. There is no mention of AI or ML algorithms for analysis, interpretation, or prediction.
No
The device is described as a "diagnostic tool to measure" lung function, not to provide therapy or treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the CardioTech Spirometry System is a "diagnostic tool."
No
The device description explicitly states that the system consists of a spirometer and a flow sensor, which are hardware components. The software is used to process and manage the data from these hardware components.
Based on the provided information, the CardioTech Spirometry System, Model GT-105, is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the human body (like blood, urine, tissue) in vitro (outside the body). The CardioTech Spirometry System measures the flow and volume of air moved in and out of the patient's lungs in vivo (within the body).
- The device description focuses on measuring physiological parameters related to lung function through breathing maneuvers. This is a direct measurement of a physiological process, not an analysis of a biological sample.
Therefore, the CardioTech Spirometry System is a diagnostic device, but it falls under the category of in vivo diagnostic devices rather than in vitro diagnostic devices.

Intended Use / Indications for Use
The CardioTech Spirometry System, Model GT-105, is a diagnostic tool to measure the maximal volume and flow of air that can be moved in and out of a patient's lungs. The system is intended for use with pediatric (4 to 17 years) and adult (18 to 99 years) patients in hospitals, physician's offices, laboratories, and occupational health environments.

Device Description
The CardioTech GT-105 Spirometry System measures a wide range of physiological parameters such as SVC, FVC, MVV, and MV and consists of a spirometer and a flow sensor.
The flow sensor head, which includes a flow air resistance element, is mounted on the flow sensor body. Via a disposable mouthpiece and filter, the patient breathes as instructed through the flow sensor head. The pressure transducer in the spirometer then measures the differential pressure in the flow sensor head which is digitized into 12 bit data by an A/D converter.
The data can be transferred via RS-232C/USB interfaces to a PC in which Spirobank software is installed. Since the software includes a number of screens and 'buttons' that help to logically perform the function, the medical practitioner (e.g., technician) can print (reports), save and recall the data/results.
