Overview

Make INVOS™ cerebral/somatic oximetry your new monitoring modality

With the new INVOS™ regional oximetry strategic partner solution, adding noninvasive brain oxygenation and tissue perfusion patient monitoring to your portfolio is easy and efficient.

The new INVOS™ regional oximetry strategic partner solution is the first external fully-featured NIRS-based cerebral/somatic oximetry available for OEM integration.

Clinicians are increasingly adopting regional saturation monitoring for the early detection of cerebral hypoxia([FOOTNOTE=Vretzakis G, Georgopoulou S, Stamoulis K, et al. Cerebral oximetry in cardiac anesthesia. J Thorac Dis. 2014;6 Suppl 1:S60-69.],[ANCHOR=],[LINK=]) and to monitor changes in perfusion in neonates and infants. By integrating INVOS™ technology you can offer your customers the unique benefits of market-leading INVOS™ technology.

  • Clinical standard in regional oximetry
  • Evidenced-based claims for improved patient outcomes
  • Unique sensor designs optimized for adults, pediatric and infant/neonatal patients
  • An integrated solution with rSO2 data transfer and electronic medical record (EMR) connectivity
  • Patient-specific rSO2 baseline measurements, including calculation of area under the curve (AUC) and trend line averaging
  • USB functionality for rSO2 data offload and analysis

Features

Developed as a complete packaged OEM system, the INVOS™ Regional Oximetry Strategic Partner Solution includes:

  • INVOS™ monitor interface cable
  • INVOS™ preamplifier (s) – channel 1/2 ; optional channel 3/4
  • INVOS™ reusable cable sensors (two per preamplifier)
  • INVOS™ USB drive

The external cable design offers a simple technical integration without the mechanical space constraints of standard PCBA platform designs. And, the INVOS™ regional oximetry strategic partner solution provides the same full complement of features and functionality as the INVOS™ 5100c monitor, including:

  • EMR-compatible, seamless transmission of rSO2 data through networked monitoring platforms
  • USB port and USB exported data formats for data offload and management needs in STS reporting, as well as rSO2 and case analytics
  • Full parameter set of INVOS™ rSO2 values and clinical data including:
    • Regional saturation (rSO2) – per channel
    • Baseline – per channel
    • Trend average (60 minute average rSO2)
    • % change from baseline (% rSO2)
    • Signal strength indicator (SSI)
    • Area under the curve
  • Compatibility with all INVOS™ sensors – adult, pediatric and neonatal
  • INVOS™ OEM evaluation and development kits for rapid and efficient platform integration, scoping and execution
  • Backed by a global team of Medtronic OEM technical, clinical and marketing experts

Data Exchange Summary

The INVOS™ regional oximetry strategic partner solution communicates with the host monitor through asynchronous serial communication (RS-232). The protocol is packet-oriented with binary data and ACK/NAK handshaking. Beyond the regular reporting to the host of the INVOS™ output parameters, in the data exchange the host can:

  • Retrieve hardware and software revision information for compatibility control
  • Configure INVOS™ device settings (baud rate, date format, etc.)
  • Configure INVOS™ case settings (alarm limits, case type, channel labels, etc.)
  • Report user-initiated clinical event markers for INVOS™ monitor interface cable recording, stored for reporting during USB data offload
  • Instruct the INVOS™ monitor interface cable to offload internally stored case data to a connected USB drive

Safety Specifications

The INVOS™ regional oximetry strategic partner solution, a component to be integrated into and be part of an OEM partner’s system, has been designed to comply with the electrical safety requirements of IEC 60601-1 (both second and third editions). Compliance of the component was tested and proven by a third-party accredited test facility while integrated into a Medtronic-designed representative system. The test report may be obtained from Medtronic upon partner request.

The preamplifier of the INVOS™ regional oximetry strategic partner solution provides the required degree of patient isolation for a type BF applied part.

Compliance of the OEM partner’s system, including the integrated INVOS™ regional oximetry strategic partner solution, is the responsibility of the system provider.
