Detect Hypoxic Events Up To 90 Seconds Earlier for Critically Ill Patients1.

The Nellcor™ SpO2 forehead sensor detects hypoxic events 90 seconds faster([FOOTNOTE=Bebout DE, Mannheimer PD, Wun C-C. Site-dependent differences in the time to detect changes in saturation during low perfusion. Crit Care Med. 2001;29(12)A115.],[ANCHOR=View Abstract],[LINK=/content/covidien/websites/medtronic/com/en/covidien/support/clinical-evidence.html?id=805201]),([FOOTNOTE=A technology overview of the Nellcor™ OxiMax™ pulse oximetry system. Internal testing.],[ANCHOR=],[LINK=]),([FOOTNOTE=MacLeod DB, Cortinez LI, Keifer JC, et al. The desaturation response time of finger pulse oximeters during mild hypothermia.

When a patient is in respiratory distress and SpO2 is lower than 80%, accurate real-time information is crucial for the right clinical decisions. The unique Expanded Accuracy LoSat™ Accuracy Range 60% to 100% empowers patient management in challenging situations([FOOTNOTE=FDA 510(k).],[ANCHOR=],[LINK=]).

Nellcor™ pulse oximetry with OxiMax™ technology specifies a highly accurate measurement of SpO2, even in some of the most challenging patients1.

The Nellcor™ SpO2 forehead sensor:

  • Provides an expanded LoSat accuracy range of 60% – 80% SpO2 +/-3 and delivers reliable readings in challenging conditions2
  • Designed for an accessible sensor site-the forehead is generally easier to reach and less prone to motion than hands
  • Can be used with mechanically ventilated patients
  • Enables monitoring of patients from pediatric (weighing more than 10 kg) to adult
  • Single-patient use, featuring long-lasting, four-layer adhesive
