Pulsoximeter Contec RS01. anyone tried it ?

Hello!
I have used a pulse oximeter Contec CMS-50F with good results. Have convinced a friend to go to the doctor now, after he has seen data on oxygenation during the night. It's good.

But I wonder if anyone has tried Contec's pulse oximeter RS-01, which also measures the airflow in the nose, and also measures the apnea and hypopnea?
I understand that the quality of the respiratory flow can not be compared to that of a cpap collect. But as a tool to convince people to go to the doctor and do a proper sleep study. Anyone tried it?

Never used one, looks interesting, but a little on the costly side

range of accuracy on the SpO2 is above 70% so better than some of the other models. The sites that talk about it really only show rpm, or respiration per minute graph. - where did you find all the details that you found?

I have previously purchased a CMS-50F by a company called China Medical, and now I emailed "Mandy" on the company and asked. Mandy emailed manual and a printout from reports. If anyone is interested I can email it on. 9.1 MB
