More Information

There’s no such thing as an SpO2 simulation! Why a primary calibration reference does not exist and how to properly measure SpO2 accuracy?

For the majority of human vital signs, simulation is a direct analog of the clinical signal. However for SPO2 simulation, no primary calibration exist. Simulation of oxygen saturation in humans, presents a challenge. Especially as each patient monitor manufacturer/patient monitor uses it’s “own R-Curve” to derive and display saturation.
Find out how functional SPO2 testers are dealing with these different “R-Curves” and how these testers properly measure SPO2 accuracy.

Testing of Medical Patient Monitors

Durable medical equipment is depended on for support of patient diagnosis and therapy, so it must be safe, effective, and reliable; also regular testing is required. If you are being asked to perform multiple tests on patient monitor devices, meet below the ProSim 8 Vital Signs Patient Simulator. Along with time-saving features like standardized test templates, stay-connected ECG posts, and barcode scanning, the ProSim 8 is a single portable unit, which can automate testing of a broad range of physiological parameters on patient monitors.

Light compliance and medical computer monitor grayscale check with RaySafe X2 light sensor

the RaySafe X2 Light Sensor is one of the approved light sensors supported by both Barco’s (QAWeb) and Eizo’s (RadiCS) software for calibration and compliance test of medical monitors. See the attached example of a grayscale contrast compliance test conducted in QAWeb based on the TG 18 test patterns.
The conducted test in the attached report is a so-called DICOM GSDF (GrayScale Standard Display Function) test checking that monitors correctly display the contrast between different luminance values of the whole grayscale.
