Intended Use

The Vios Monitoring System (VMS) is intended for use by medically qualified personnel for physiological vital signs monitoring of adult (18+) patients in healthcare facilities. It is indicated for use in monitoring of 7-Lead ECG, heart rate, respiratory rate, pulse rate, functional oxygen saturation of arterial hemoglobin, non-invasive blood pressure (NIBP) continuously, and patient posture and activity. VMS allows for the input of non-invasive blood pressure and body temperature and can display data from peripheral devices. VMS can generate alerts when rate-based cardiac arrhythmias are detected and when physiological vital signs fall outside of selected parameters. The non-invasive Blood Pressure Tracking feature is based on Pulse Arrival Time (PAT), which is obtained utilizing ECG and PPG signals following a calibration process using an FDA-cleared oscillometric blood pressure monitor. This feature is not intended for use in critical care environment. The Vios Central Station Monitor (CSM) and Central Server (CS) Software (SW) is indicated for use by healthcare professionals for the purpose of centralized monitoring of patient data within a healthcare facility. The Vios CSM SW and CS SW receives, stores, manages, and displays patient physiological and waveform data and alarms generated by Vios proprietary patient vitals monitoring software.

Device Story

Wireless mobile platform for healthcare facility patient monitoring; includes Chest Sensor, Finger Adapter, Central Server, and Central Station Monitor. Chest Sensor acquires 3-channel ECG, bioimpedance, 2-channel pulse oximetry, and tri-axial accelerometer data; transmits via Bluetooth to BSM software. NIBP tracking uses Pulse Arrival Time (PAT) derived from ECG and PPG signals; requires calibration via FDA-cleared oscillometric cuff. System generates alerts for arrhythmias and out-of-range vitals. Healthcare professionals use Central Station to view, manage, and store patient data. Enables continuous monitoring, facilitating clinical decision-making through real-time physiological data and alarm notifications.

Clinical Evidence

Clinical testing performed per ISO 81060-2, IEEE 1708, and ISO 81060-3 using radial artery invasive blood pressure as reference. Results met acceptance criteria and were similar to predicate. System validation testing and compliance testing per IEC 80601-2-30 conducted. Previous system performance verified via electrical safety (IEC 60601-1), EMC, biocompatibility (ISO 10993), and pulse oximetry/respiratory rate clinical testing.

| Device Description: | The Vios Monitoring System (VMS) Model 2050 is a wireless mobile medical device platform that allows caregivers in healthcare settings to monitor patient vitals.
The VMS includes a proprietary monitoring software, Chest Sensor, Finger Adapter and Central Server and Central Monitoring Station.
The VMS BSM SW Model B2050 is stand-alone software that can receive, analyze, and display physiological vitals data from one or more patient-worn sensors via standard communication protocols (Bluetooth™). It runs on a commercial IT platform and is intended to be used in conjunction with the Vios Chest Sensor and Vios Lead Adapters and can support peripheral, medical grade, Bluetooth™-enabled devices.
The VMS Chest Sensor Model CS2050 is a small, patient-worn, non-sterile multiple use, and rechargeable sensor that acquires 3-channel ECG, bioimpedance, 2-channel pulse oximetry, and tri-axial accelerometer data. The sensor contains signal acquisition firmware (embedded software) and wirelessly communicates acquired data via standard communication protocols (Bluetooth™) to the BSM SW for analysis and display. The Chest Sensor has a button that, when pressed, sends a patient call alert to the BSM SW.
VMS Chest Sensor Adapter Models L2050F (Pulse Ox Finger Adapter) are plastic, non-sterile, patient-worn, multiple use pulse oxygenation sensors that connect to the Vios Chest Sensor and are secured to the patient via medical grade ECG electrodes. |

| --- | --- |
| Summary of Substantial Equivalence | The subject device has been updated with software modifications (addition of algorithm for blood pressure tracking and supporting UI modifications) which has similar technological characteristics as that of primary predicate, K130709. The features other than blood pressure tracking and the physical components remain unchanged from the secondary predicates (K172586 and K173107).

Vios Central Station Monitor/Central Server essentially remains the same apart from UI modifications to support blood pressure tracking.

• Basic Principle: The subject device tracks blood pressure via PAT (Pulse Arrival Time) using the time delay between ECG measured from the chest and the pulsatile PPG waveform measured at the base of finger/thumb using the pulse oximeter of the subject device. The sensors unit for ECG and PPG remains the same as K172586 and for the blood pressure tracking, the same underlying principle is used by the primary predicate, Visi Mobile Monitoring System, K130709.

• Calibration (initialization): For tracking the blood pressure based on PAT, it requires coefficients from an input blood pressure for calibration. This characteristic is the same as the Visi Mobile Monitoring System (K130709). The predicate and the subject device are calibrated to a specific oscillometric cuff device. Both the subject and predicate devices can only be calibrated when the PAT is stable, and the calibration is achieved by pairing PAT during cuff inflation with the BP readings of the calibration device during the same cuff inflation period. Thus, the method of calibration remains the same between the subject device and the predicate.

• Device Performance: The clinical study was performed across a range of subjects, representative of the intended population, to validate this measured change. The results demonstrate the performance meeting the all consensus standards requirement and are substantially equivalent to the predicate device.

The subject device has been verified and clinically validated to meet the requirements of the recognized consensus standards. The results demonstrate that essential technological characteristics between the subject device and the predicate devices are the same, and do not raise new questions about safety or effectiveness, and testing establishes equivalent performance as compared to predicate devices. |

| Summary of Non-Clinical, Clinical, and Conformance Testing | The bench (non-clinical) testing for the addition of blood pressure tracking feature to the VMS Model 2050 is done using system validation testing and compliance testing for applicable clauses according to IEC 80601-2-30.

The clinical testing and analysis is performed according to applicable clauses from ISO 81060-2, IEEE 1708, and ISO 81060-3 for validation using reference invasive blood pressure measurement on the radial artery. The results were within the acceptance criteria, similar to the predicate device.

The other system performance remains unchanged from the predicate (K172586) and show conformance to:
- Electrical safety, EMC, and vitals sign monitoring standards (IEC 60601-1, IEC 60601-1-2, IEC 60601-1-8, IEC 60601-2-27, IEC 60601-2-49, EC53)
- Biocompatibility standards (ISO 10993)
- Transportation Simulation testing (ASTM D4169-16)
- Software development life cycle (EN 62304)
- Usability and human factors standards (EN 62366)
- Risk Management (ISO 14971)
- Pulse oximetry clinical testing (ISO 80601-2-61)
- Respiratory Rate clinical testing
- Standard for evaluation of Wireless Coexistence (ANSI C63.27) |
| --- | --- |
| Conclusions | Based on the results from the non-clinical and clinical tests, Murata Vios considers the Vios Monitoring System to be as safe, as effective and substantially equivalent to the legally marketed predicate devices. |
