Four of the 6 oximeters tested showed large errors (up to -6.30% mean bias, precision 4.30%, 7.53 ARMS) in estimating saturation when SaO2 was reduced <80%, and half of the oximeters demonstrated large errors when estimating saturations between 80% and 90%.Two of the pulse oximeters tested (Contec CMS50DL and Beijing Choice C20) demonstrated ARMS of <3% at SaO2 between 70% and 100%, thereby meeting International Organization for Standardization (ISO) criteria for accuracy.මම මේක බලල ගත්තේ Contec CMS50DL. $14 වෙන්නේ<a href="https://www.ebay.com/itm/133720807928" target="_blank">https://www.ebay.com/itm/133720807928</a></blockquote>
