Which R-curves do I need to download?

The R-curves you need to download is dependent on the version of the Puls-R SpO2 Finger Simulator you have purchased.

If you procured your accessory prior to March 2024, the likelihood is that you have a 1st generation model and require our MK I R-curves, which can be found in the download section below.

If you have our new 2nd generation model, you will see a ‘Rev 2’ QR code on the reverse of your unit, as shown in the image below. In this scenario, it is imperative that you download the newest MK II R-Curves.

Please note, if you update the firmware of your Uni-Sim to version 4.14, both MK I and MK II R-curves will be installed on your device. If you’re using an older model, please download the new R-curves below.
