Tissue Oximetry System

The Small Sensor to Make a Big Difference

OxyPrem's non adhesive sensor is a solution that is specifically designed for the smallest patients with the clinical need in mind: simple to use, reusable, and affordable to hospitals worldwide. 

Sensor designed specifically for your smallest patients 

Using 10+ wavelengths of light and a dynamic calibration approach, our advanced technology maximises robust signal processing while minimising surface signal contamination to ensure reliable and accurate continuous monitoring. 

Advanced algorithms

NOAH uses liquid phantom validation, a progressive benchmark approach which was recently included within the international safety and performance standards for cerebral oximetry monitors.

This approach enables reproducible validation over a broad range of oxygenation and haemodynamic states of neonatal physiology. 

Gold Standard validation 

NOAH provides a high quality, accessible and cost-effective solution to support routine standard monitoring in critical care worldwide. 

Cost effective, accessible continuous monitoring 


Quantifying the effect of adipose tissue in muscle

We measured StO2 of a liquid phantom by 3 continuous wave (CW) oximeters (Sensmart Model X-100 Universal Oximetry System, INVOS 5100C, and OxyPrem v1.3), as well as a frequency-domain oximeter, OxiplexTS, through superficial layers with 4 different thicknesses

In vivo precision assessment in neonates

We estimated the precision of the OxyPrem tissue oximeter to be ≤ 1.85 %.

Comparison of tissue oximeters on a liquid phantom (extension)

We evaluated the NIRS oximeters FORE-SIGHT, NIRO and SenSmart, and reproduced previous results with the INVOS and OxyPrem v1.3 oximeters.

Comparison of tissue oximeters on a liquid phantom

We made a blood-lipid phantom simulating the neonatal head to determine the relation between oxygenation values obtained by different oximeters.

Used in hospitals from 11 countries. Learn more about our first product.
The self-calibrating, non-adhesive sensor is gently placed on the patient. To keep it in place, it can be positioned underneath the CPAP cap or be attached with a bandage.

Reusable and Trustworthy

NOAH is a neonatal specific, next-generation NIRS monitoring system that uses a high-precision reusable sensor to provide real-time, continuous tissue oximetry which you can trust.
