Intended Use
The CORTEX METALYZER pulmonary function stationary test system is a device which monitors the cardio-respiratory functions during stress testing, rehabilitation, sports medicine and other related activities. The METALYZER system provides predictive nulmonary function values using the monitored and derived parameters. This device is for use in a laboratory or facility setting and may be used with adults and children over the age of 14 years.
Device Description
The CORTEX METALYZER metabolic test system is a stationary device, which can monitor parameters during laboratory testing or simulated conditions. The device is comparable to the Jaeger Oxycon Alpha system. The device is software driven. Adequate software testing with respect to the new IEC 601-1-4 has been conducted on the device. The device is electrically operated.
More Information

No
The document does not mention AI, ML, or related terms, and the description focuses on standard physiological monitoring and predictive values based on monitored parameters, not on learning algorithms.

No
The device monitors cardio-respiratory functions and provides predictive pulmonary function values, but it does not treat or alleviate any condition.

Yes

The device monitors cardio-respiratory functions and provides predictive pulmonary function values, which are used to assess the current health status of a patient and indicates that it is a diagnostic device used to provide health information.

No

The device description explicitly states it is a "stationary device" and "electrically operated," implying the presence of hardware beyond just software. While it is "software driven," this does not mean it is exclusively software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use describes monitoring cardio-respiratory functions during stress testing, rehabilitation, sports medicine, and related activities. This involves measuring physiological parameters directly from the patient's body (e.g., breathing, heart rate) rather than analyzing samples in vitro (outside the body).
  • Device Description: The description mentions a "metabolic test system" that monitors parameters during testing. This aligns with in-vivo measurements rather than in-vitro analysis of samples.
  • Lack of IVD Indicators: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or performing tests on these samples outside the body, which are hallmarks of IVD devices.

Therefore, the CORTEX METALYZER is a physiological monitoring device, not an In Vitro Diagnostic device.

510(K) Summary Differences and Similarities

As reviewed in Section 10 the Metalyzer pulmonary system is fundamentally similar to the predicate device. This summary reviews the:

Intended Use Applications Usage Location Technological characteristics

Intended Use:

Both the Metalyzer and predicate device have the same intended use.

Applications:

Both products are used in applications such as stress testing, rehabilitation, sports research and medicine and occupational medicine.

Usage Location:

The Metalyzer and predicate device are designed for use within a laboratory or facility setting.

Technological Characteristics:

These products have very similar technology in their components.

Similarities:

Volume Transducer - Both use digital rotameter. Carbon Dioxide Sensor - Non-dispersive infrared in both systems. Heart Rate Sensor - Polar Belt used in both units. Data Collection - A choice of mask or mouthpiece for collecting data offered in both. Predictive Value Calculations - Both systems measure the same values and then oalulate values for pulmonary function.

Differences:

Oxygen Sensor – The Metalyzer uses a Galvanic Fuel Cell while the predicate device a Paramagnetic Cell. Both types are considered standard technology & or oxygen measurement.
