No
The document describes a simple electrode and its function in transmitting electrical signals for bioimpedance measurements. There is no mention of AI or ML in the device description, intended use, or performance studies.
No.
The device is described as monitoring hemodynamic parameters and ventilatory parameters, and it functions as an electrode to transmit electrical signals for sensing, not for delivering therapeutic treatment.
Yes
The device monitors "hemodynamic parameters including stroke volume, stroke index. heart rate, cardiac index, cardiac output, and total peripheral resistance; and the ventilatory parameter, respiratory rate," which are all physiological parameters used to assess and understand a patient's health status, making it a diagnostic device.
No
The device description explicitly details physical electrodes that are applied to the patient's skin and transmit electrical signals. This indicates a hardware component, not a software-only device.
Based on the provided text, this device 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.
- Device Function: The description clearly states that the NICaS™ electrode is used to "transmit electrical signals to and from the skin and the NICaS™ 2001 cardiorespiratory system." It measures physiological parameters like stroke volume, heart rate, and cardiac output by conducting a current through the skin and using bioimpedance.
- No Sample Analysis: There is no mention of analyzing any biological samples from the patient. The device interacts directly with the patient's body to gather electrical signals.
Therefore, the NICaS™ electrode, as described, is a medical device used for in vivo monitoring of physiological parameters, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The NICas™ electrode is used only in conjunction with the NICaS™ 2001 and all other NICaS™ devices.
The function of the NICas™ electrode is unchanged from that of the Nicolet Biomedical Instruments Velcro ground strap in the original NICas™ 2001 cardio-respiratory system,(510(k)K942227) submission, namely, to transmit electrical signals to and from the skin and the NICaS™ 2001 cardiorespiratory system.
The indications for use of the NICas™ 2001 cardio-respiratory system remain unchanged from those included in the original NICaS™ 2001 cardio-respiratory system, (510(k) K942227), namely, monitoring hemodynamic parameters including stroke volume, stroke index. heart rate, cardiac index, cardiac output, and total peripheral resistance; and the ventilatory parameter, respiratory rate. The device is intended for use in male and female patients with cardiovascular disorders including:
- . patients undergoing cardiac catheterization
- . cardiac surgery patients
- . patients in intensive and cardiac care units
- . patients in rehabilitation centers

Device Description
The NICaS™ Electrodes are fixed to intact skin of the arms and legs of a patient that is to be monitored for cardiac output. The electrodes employ a biocompatable conductive adhesive to maintain their position for up to 24 hours of continuous monitoring. As stated in the original submission, the electrodes conduct a 1.4 mA, 32.5 KHz current to the skin from the NICaS™ 2001 Noninvasive Cardio-Respiratory System (K942227) which uses the principle of bioimpedance to determine various cardiac parameters including cardiac output. The change from the strap type electrodes included in the original submission will permit longer term patient monitoring. The change in electrodes does not require any changes to the NICAS™ 2001 Noninvasive Cardio-Respiratory System itself. The electrodes continue to be attached to the two identified input connectors of the patient module. The patient module also connects with the computer.
The electrode design is similar to the Katecho, Inc. K-Defib/Pace Pediatric Electrode (K954505). The materials and manufacturing methods are the same, therefore no new biocompatability issues are raised. The only change is that the size and shape of the electrode has been modified for ease of use in the clinical setting.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The performance characteristics of the NICaS™ Electrode have been measured over the full 24 hour recommended period of use in a study employing volunteers. This study was performed by N.I. Medical. It demonstrated that cardiac output data gathered at several points during the 24 hour period are stable throughout the observation period. A second study performed by N.I. Medical on normal volunteers confirmed that cardiac output data gathered using the new electrodes closely correlated with data obtained using the Nicolet Biomedical electrodes.
