E1 Ear Sensor

Product catalog summary

Overview
The document discusses the E1 Ear Sensor, a single-patient-use device designed for faster detection of oxygen saturation changes, particularly in low perfusion conditions. It highlights the advantages of using ear sensors over traditional digit and forehead sensors.

Advantages of Single-Patient-Use Sensors

Avoids cross-contamination risks.
Reduces complexity in managing reusable sensors.

Advantages of Head versus Digit Monitoring

Faster detection of desaturation/resaturation during low perfusion.
Alternative monitoring site during surgeries or when digit access is not possible.
Reliable measurements during extremely low perfusion.
Hands-free monitoring and potential advantages for pleth variability monitoring.

Advantages of Ear versus Forehead Monitoring

Alleviates accuracy limitations of forehead sensors.
Alternative to digit sensors when forehead site is unavailable.

Advantages of Cavum Conchae versus Ear Lobe Monitoring

More secure placement than traditional clip-style sensors.
Better perfusion for improved signal quality.

Features and Benefits
The E1 Ear Sensor is noted for detecting hypoxemia faster, which is crucial during airway management and resuscitation. It combines Masimo SET performance with a reliable alternative monitoring site while minimizing cross-contamination.

Technical Specifications

Faster response to oxygenation changes during low perfusion. Advantages of Single-Patient-Use versus Reusable Sensors >> Avoids cross-contamination risks >> Reduces complexity of reusable ear sensor management (cleaning, storage, and inter-departmental transport) While Masimo SET® Measure-through Motion and Low Perfusion™ pulse oximetry overcomes the limitations of conventional pulse oximetry and offers 97% sensitivity and 95% specificity for alarms during motion and low perfusion conditions1, there are still some advantages to monitoring on the head such as faster response to oxygenation changes...
