Description

CMI Health OxyKnight CF-100 Bluetooth fingertip pulse oximeter

The CMI Health CF-100 is a Bluetooth fingertip pulse oximeter that measures blood oxygen saturation (SpO2), pulse rate, perfusion index and respiration rate. Results show in about four seconds on an OLED display that can be viewed in four orientations.

It pairs with the free OxyKnight app and also works with the AsthmaGo app. An adjustable audio alarm warns of abnormal pulse or oxygen levels, and anti-motion and low-perfusion handling help when you move or have weak circulation.

The CF-100 weighs 54 g and runs on two AAA alkaline batteries for up to 24 hours of continuous measurement. CMI describes it as suitable for adults and children. It is for monitoring, not diagnosis, so discuss your readings with your doctor.
