No
The summary describes a device based on esophageal Doppler techniques and mentions an improved user interface and replaced components, but there is no mention of AI or ML.
No
The device provides real-time monitoring information about a patient's left ventricular blood flow and hemodynamic parameters, which is used by clinicians to evaluate and optimize performance, not to directly treat a condition.
Yes
The device "provides clinicians with real-time information about a patient's left ventricular blood flow and key hemodynamic parameters" and "can be used by the managing clinician to evaluate and optimize hemodynamic performance." This function of providing information and evaluating performanceเพื่อ inform clinical decisions falls under the definition of a diagnostic device.
No
The device description explicitly states that the system employs esophageal Doppler techniques using a 4 MHz continuous wave Doppler ultrasound, which is a hardware component. It also mentions replacing obsolete components, further indicating hardware is involved.
Based on the provided information, the CardioQ-EDM cardiac function and fluid status monitoring system is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- CardioQ-EDM's function: The CardioQ-EDM system uses esophageal Doppler techniques to monitor blood flow and hemodynamic parameters within the patient's body (specifically, the descending thoracic aorta). It does not analyze samples taken from the body.
Therefore, the CardioQ-EDM is a medical device used for in vivo monitoring, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The CardioQ-EDM cardiac function and fluid status monitoring system is designed to provide clinicians with real-time information about a patient's left ventricular blood flow and key hemodynamic parameters. The CardioQ-EDM's beat-to-beat data on cardiovascular status can be used by the managing clinician to evaluate and optimize hemodynamic performance in anesthetized, sedated or conscious sedated patients in the operating room, intensive care unit, emergency room or ward.

Device Description
The CardioQ-EDM system employs esophageal Doppler techniques using 4 MHz continuous thoracic aorta, displaying this data as a maximum velocity curve, a descriting there is derived measurements. Thus, real-time information about verouty opesant in particular left ventricular flow, is displayed continuously.
Deltex CardioQ-EDM System design: Esophageal probe transmits and receives 4 MHz Continuous Wave Doppler (CWD) ultrasound to measure blood flow velocities in the descending thoracic aorta. Signals are returned via the Patient Interface Cable (PIC) to CardioQ-EDM Monitor. CardioQ-EDM Monitor processes the signal and displays it as real-time spectrum, to show the distribution of red blood cell velocities over the entire cardiac cycle. Maximum velocity envelope is continuously delineated and used to calculate velocity-integral of the waveform during systole.

Dear Mr. Brookfield:
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 (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. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
