What is the Nautilus Delta by Romedex?

Wireless ECG based Catheter Guiding System

The Nautilus DeltaTM system consists of the following elements:single use sterile ECG extension cable, non-sterile ECG cable, patient module (ECG data acquisition and processing plus integrated remote control), and  mobile medical application  running on any mobile platform which complies with the minimum requirements.

Nautilus DeltaTM provides real-time catheter tip location information by using the patient’s cardiac electrical activity (ECG). This information can be used to position any commercially available central venous catheter at or around the cavo-atrial junction (CAJ). Nautilus Delta supports navigation of central venous catheters from the vascular access point towards the CAJ by computing and displaying a navigation signal.

Nautilus Delta also displays on its graphical user interface the surface (skin) ECG signal, a marker identifying the R-peak, and the patient’s heart rate. In order to obtain intravascular ECG information at the tip (distal end) of a catheter, a stylet or a guidewire inserted in the catheter can be connected to Nautilus Delta patient module via the sterile Nautilus adaptor (the sterile ECG extension cable).

Benefits of the Nautilus Delta by Romedex

The Nautilus Delta is a new wireless system with many advantages of delivering IC-ECG optimal clinical performance compared to ECG monitors. First of all it is light and easy to carry making it flexible and easier for bedside insertion and patient accessibility.

The Nautilus Delta has a major advantage in that it can be utilized on a portable device with easy access to data storage and printing. Documentation and other practical uses are therefore maximized.

Features and Technical Details of the Nautilus Delta by Romedex

Introduction: The intracavitary ECG method (IC-ECG) is adopted in clinical practice for assessing the central location of the tip of venous access devices (VAD). We report our preliminary experience with a new wireless system specifically dedicated to the IC-ECG (Nautilus Delta (aka Handy), Romedex), which consists of a small box connected to the ECG cables, sending data to a smartphone or a tablet by bluetooth technology.
The phone/tablet is provided with a software application which allows to display both the surface and intracavitary ECG.

Method: The IC-ECG method is performed according to the standard procedure. The identification of the peak of the P wave (corresponding to the cavo-atrial junction) is made easy by the freeze function, which can be operated either from the box or from the phone/tablet.

Results: The new device was adopted for tip location in 207 central VADs (154 PICCs, 49 ports, 2 short term CVCs and 2 cuffed-tunneled catheters) placed after cannulation of different veins (96 basilic, 41 brachial, 57 axillary-subclavian, 6 internal jugular, 7 brachio-cephalic) . The P wave was evident on basal ECG in all patients. A peak of the P wave was easily detected in all patients. In 36 patients (28 PICCs and 8 ports), the procedure was simultaneously carried out both with a standard dedicated ECG device (Nautilus, Romedex) and with Handy: no differences were noted in terms of performance.

Discussion and conclusions: This new wireless system for IC-ECG had an optimal clinical performance in terms of applicability and feasibility. Transmission of the data to the moveable device by bluetooth simplified the wire connections. Some potential advantages over other ECG monitors are: the system is light and easy to carry – which makes it ideal for bedside insertion; it can be operated by the same professional inserting the VAD; it implies no risk of electrical hazard; it can be used on a personal portable device, allowing easy storage of data and easy printing for documentation.
