The summary describes standard hemodynamic monitoring techniques (thermodilution, Pulse Power analysis, reflectance spectrum) and does not mention any AI/ML algorithms or capabilities.
No
The device is described as a "Hemodynamic Monitoring System" intended for diagnostic and prognostic evaluation by a clinician, measuring and calculating physiological parameters such as cardiac output and oxygen saturation. It monitors and calculates, but does not provide direct therapy.
Yes
The "Intended Use / Indications for Use" section states that the system is "intended for patients for whom the monitoring of continuous cardiac output and calculated hemodynamic parameters is indicated for diagnostic and prognostic evaluation by a clinician."
No
The device description explicitly states that the Cogent™ HMS consists of a base unit (patient interface module, PIM), a dedicated touch-screen display unit (user interface module, UIM), associated cables, and a physically separate optical module (OpMod). These are hardware components, not just software.
Based on the provided text, the Cogent™ Hemodynamic Monitoring System (HMS) is an In Vitro Diagnostic (IVD) device.
Here's why:
- Measures and calculates parameters from blood: The device is explicitly stated to "measure and calculate venous oxygen saturation in patients" and "monitors venous oxygen saturation by measuring the reflectance spectrum of the blood." It also measures cardiac output and other derived hemodynamic parameters, which are obtained through catheters inserted into the patient's circulatory system. While cardiac output isn't directly measured from a blood sample in the traditional sense of a lab test, the measurement of venous oxygen saturation directly involves analyzing properties of the blood itself.
- Used for diagnostic and prognostic evaluation: The intended use states it's for "diagnostic and prognostic evaluation by a clinician." This aligns with the purpose of IVD devices, which are used to provide information for diagnosis, monitoring, or prognosis of a disease or condition.
- Requires catheters and sensors: The device relies on catheters and sensors that interact with the patient's internal environment (blood vessels) to obtain the necessary data.
While the device is a monitoring system used in a clinical setting, the core function of measuring venous oxygen saturation from blood makes it fall under the definition of an In Vitro Diagnostic device.
