## Questions & Answers

**Q: Why is this Nonin model so expensive compared to other Nonin models?**
A: All Nonin SPO2 Pulse Oximeters monitors are usually costlier than other Pulse Oximeters. This is down to the quality and accuracy. Nonin 9550 in particular is highly accurate even on dark skin and patients with low perfusion.  The accuracy present in the bigger devices found in hospitals is packed this small device. It can be used on a wide variety  of finger sizes (meaning can be comfortably used on children and adults). It is approved for use by US Army and Air Force and found to be suitable for use in air as well.
