E1® Ear snsor

Product catalog summary

Introduction
The E1 Ear Sensor is designed for single-patient use, specifically for the ear concha. It provides an alternative to digit sensors, especially useful when finger access is not possible or during specific monitoring scenarios like brain function or cerebral oximetry monitoring.

Advantages

Allows easy access during surgery and resuscitation.
Less susceptible to changes in peripheral perfusion compared to digit sensors.
Faster detection of desaturation and resaturation events compared to digit sensors.

Specifications

Accuracy (ARMS): Oxygen Saturation (SpO2%) range of 70%—100% with an accuracy of ±2.5% for both adults and pediatrics under no motion and low perfusion conditions.
Pulse Rate: Range of 25—240 bpm with an accuracy of ±3 bpm under no motion and low perfusion conditions.
Compatibility: Compatible with Masimo or OEM monitors with Masimo SET® or rainbow SET™.
Weight Range: Suitable for patients over 30 kg for ear application.

Ordering Information

Single-patient-use, non-sterile, and latex-free.
Packaged 10 per box with part numbers LNCS E1 (2918) and M-LNCS E1 (2919).

Regulatory Information
Federal (USA) law restricts this device to sale by or on the order of a physician. Full prescribing information, including indications, contraindications, warnings, and precautions, is available in the instructions for use.

Conclusion
The E1 Ear Sensor offers a secure placement on the cavum concha and provides a reliable alternative to traditional clip-style ear lobe sensors, ensuring faster response to oxygenation changes, especially in low perfusion conditions.
