For Patient Care Anywhere

The Nellcor™ Oximetry Advantage

The Nellcor™ N-­85 pulse oximetry monitor delivers exceptional pulse oximetry performance even during low perfusion and signal interference([FOOTNOTE=FDA 510(k).],[ANCHOR=],[LINK=]). Nellcor™ specialty sensors-including the forehead SpO2 sensor and nonadhesive SpO2 sensors-expand the clinician’s patient care options.

The Nellcor™ N-­85 hand­held pulse oximeter is convenient for spot-­checks and continuous monitoring in a variety of settings, including EMS/ED, transport, critical care, operating room and sleep lab, and for procedural sedation.

The Nellcor™ N­‐85 capnograph/pulse oximeter with OxiMax™ technology combines two highly advanced technologies in a convenient, portable device. Microstream™ capnography helps ensure accurate end-­tidal CO2 measurements and crisp waveforms, giving the clinician a clear picture of the patient’s respiratory status.([FOOTNOTE=Maddox RR, Williams CK, Oglesby H, Butler B, Colclasure B. Clinical experience with patient-­‐controlled analgesia using continuous respiratory monitoring and a smart infusion system. Am J Health Syst Pharm. 2006;63(2):157-­164.],[ANCHOR=View Abstract],[LINK=/content/covidien/websites/medtronic/com/en/covidien/support/clinical-evidence.html?id=143954])

The extensive selection of Microstream™ breath-­sampling accessories enables clinicians to monitor intubated and nonintubated patients-including those receiving supplemental oxygen.
