Frequently Asked Questions

What is PureSAT technology and why does it matter?
PureSAT is Nonin's proprietary signal processing technology that filters out motion artifact and low-perfusion interference to deliver accurate SpO2 readings even in challenging conditions. This is a key differentiator from consumer-grade oximeters, which can produce less accurate readings in these situations. For clinical and emergency use where accuracy is critical, PureSAT technology provides the reliability that healthcare professionals depend on.

What does the three-color pulse quality indicator show?
The three-color pulse quality indicator gives the clinician an immediate visual assessment of the strength and reliability of the pulse signal being detected. A strong, consistent signal is indicated by one color, while weaker or less reliable signals are indicated by different colors, alerting the user to reposition the device before relying on the reading.

Is this oximeter suitable for use on children?
Yes. The Nonin 9590 accommodates finger thicknesses from 8 mm to 25.4 mm, making it suitable for older children and adults. For very young children or infants with smaller fingers, a dedicated pediatric or neonatal probe may be more appropriate.

How durable is this oximeter for field and emergency use?
The Nonin 9590 has been drop-tested to withstand a minimum of 50 drops, making it one of the more rugged fingertip oximeters available for professional use. Its compact, lightweight design (under 2 oz) makes it easy to carry in a pocket or kit bag for EMS, field, and emergency settings.
