As a single-patient-use ear sensor that is placed securely in the cavum conchae (the deep hollow near the ear canal opening), the Masimo E1 E1^® SpO2 Ear Sensor allows clinicians to combine performance with a reliable alternative monitoring site while minimizing cross-contamination.

• Avoids cross-contamination risks
• Faster detection of desaturation/resaturation
• Alternate monitoring site with easy access during surgery, resuscitation, in patients with finger deformities or when digit access is not possible
• Offers reliable measurements during extremely low perfusion
• Allows for hands-free monitoring
• Ear site may offer advantages for pleth variability (PVI^®) monitoring to help clinicians assess fluid responsiveness
