We use the Masimo Rad-8 for my son. He is 4 and he desats in his sleep with exacerbations. It is nice to have because it gets away from that worry through the night. I like it because you can set it to whatever values you want so the alarm doesn't go off for rediculous reasons(like moving!!) It does have the sticky things for the finger or toes but it is nice for monitoring all night long. Hope this helps! I think the machine costs around 250 and the sensors are around 30 each. Hope this helps!! I also hope you can get this stuff covered by insurance. Best of luck to you!
