I have already shared with you my opinion about your device - it is beautiful and works perfectly, but I have one question. On the display I see - SpO2 - it is oxygen, on the bottom - PRbpm - it is pulse, but between there is -PI%. I do not know what this is and even my doctor does not know this.
Please can you tell me what tis is?
Thank you.
