Intended Use

The Navigator™ is indicated for the acquisition, processing, and display of hemodynamic parameters, in order to assist the clinician in achieving and maintaining a prescribed target hemodynamic stability. Mean Systemic Filling Pressure (Pms) and Heart Efficiency (En) parameters are calculated by the Navigator from Cardiac Output (CO), Mean Arterial Pressure (MAP) and Right Atrial Pressure (RAP) data, obtained directly from patient monitoring equipment, and other data obtained by manual clinician entry. The Navigator system provides a visual indication of the patient's circulatory status in relation to predetermined goals.

Device Story

Navigator is a diagnostic computer system for hemodynamic management in critically ill patients. It ingests real-time Cardiac Output (CO), Mean Arterial Pressure (MAP), and Right Atrial Pressure (RAP) data from bedside monitors, supplemented by manual clinician entries. The system processes these inputs to calculate Mean Systemic Filling Pressure (Pms) and Heart Efficiency (En). It provides a graphical display of the patient's circulatory status relative to predetermined clinical goals. Used in ICUs, ORs, and emergency departments by clinicians to assist in resuscitation and stabilization. The visual output serves as a decision-support aid, helping providers monitor circulatory state and optimize hemodynamic therapy. By providing integrated hemodynamic parameters, the device aims to assist clinicians in achieving target stability, potentially improving patient outcomes in complex critical care scenarios.

Clinical Evidence

Multi-center, open, randomized, controlled trial (n=105 MITT population). Compared Navigator-guided care vs. conventional care. Primary endpoint: mean standardized distance to the central point of the cardiovascular zone. Results demonstrated non-inferiority to conventional care (no statistically significant difference). Safety evaluation included 112 patients; adverse events were comparable between groups, with no events considered related to the device.

Technological Characteristics

Pre-programmed diagnostic computer. Inputs: CO, MAP, RAP from bedside monitors and manual entry. Outputs: Pms, En, and graphical circulatory status. Connectivity: interfaces with peripheral monitoring equipment. Software: verified and validated per ISO 14971:2007. Electrical safety: IEC 60601-1; EMC: BS EN 60601-1-2.

Indications for Use

Indicated for critically ill patients (ages 15-90, weights 40-150 kg) requiring circulatory support in ICU, OR, anesthesia, step-down, emergency, or coronary care units. Includes patients with unstable circulations, pre/post-open heart or major surgery, septic, cardiogenic, or hypovolemic shock, drug overdose, renal failure, or major trauma.

Regulatory Classification

Identification

A single-function, preprogrammed diagnostic computer is a hard-wired computer that calculates a specific physiological or blood-flow parameter based on information obtained from one or more electrodes, transducers, or measuring devices.
