SEDLine® Brain Function Monitor
A More Complete Picture Starts With More Complete Data
SEDLine, an EEG-based brain function monitor, expands the scope of real-time data and improves the management of an anesthetic case by enabling more individualized titration. Featuring 4-channels of high-quality EEG data, SEDLine provides information about both sides of the brain and yields a single sophisticated algorithm to give accurate, reliable information about a patient's response to anesthesia. Multiple screen views expand the level of information available and the convenience with which it can be received. A user-friendly package helps optimize the utility of SEDLine in the OR and the ICU.
Key Features/Benefits:
- > Access to 4-channel EEG Data Enhances Monitoring - Yields data from both sides of the brain through a single integrated algorithm
- > Patient State Index (PSI™) Provides Rapid Assessment - Color-coded numeric values clearly indicate level of sedation/anesthesia to facilitate rapid assessment
- > Density Spectral Array (DSA) Facilitates Early Response - Easy-to-interpret, high resolution graphic of bi-hemispheric activity enables immediate detection of asymmetrical activity
- > SEDLine Patient Module - Offers superior resistance to electrocautery1
Monitor Display Formats
Switching from one screen view to another is as simple as pushing a button.
> Patient State Index (PSI) Trend Screen - Facilitates fast assessment of patient status at a glance
> 4-Channel EEG Screen - Enhances insight by displaying underlying signal and a clear picture of sensor status.
> Split-Screen View - Enables quick and easy confirmation of PSI values by allowing simultaneous viewing of PSI values, trend, and real-time signal.
> Density Spectral Array (DSA) Display - Provides additional information on brain activity in a simple-to-understand format.
- • Enables viewing of EEG information from multiple locations in both hemispheres of the brain
- • Facilitates real-time detection of asymmetrical activity, enabling early response
- • Asymmetrical activity may be caused by decreased perfusion to one hemisphere2
- • Benefits patients undergoing procedures in which the circulation of one hemisphere may be compromised (e.g. carotid endarterectomy)

SEDLine Sensor
Engineered for Better Data Collection and Ease of Use
The SEDLine sensor is designed for ease in application and enhanced patient comfort while ensuring the highest quality data.
Key Features/Benefits:
- > 4 Active Leads - Collects higher volume of data in key areas of frontal lobe
- > Disposable Sensor Technology from NASA Sleep Studies - Ensures high-quality EEG signals are collected
- > Streamlined Design - Applies quickly and easily - no plastic disk to press
How to Apply
It is recommended that the SEDLine sensor be applied prior to induction to assess the patient's PSI baseline and to monitor the brain's response to the induction agents. SEDLine is designed to fit patients with a head circumference of 50 to 64 cm. To place the SEDLine sensor on a patient, refer to the following:
If a patient's skin is oily, sweaty, or has makeup applied to it, wipe with alcohol and dry before applying array. It may be necessary to use an adhesive product such as Tegaderm™ to secure SEDLine on diaphoretic patients
Peel the release liner from the SEDLine sensor and discard Center CB/CT electrodes on forehead above nose. Press firmly with palm of hand to secure.
Apply R2 on hairless area just above temple. Repeat for L2.
Insert electrode into patient cable until the stiffener latch clicks into place.
If any of the electrodes are displayed as red or blue, gently push and wiggle electrodes until all are yellow or green. Use Electrode Status Chart when adjusting electrodes.
Caution: Each SEDLine sensor is approved for use up to 24 hours. If monitoring in excess of this period is desired, replace the SEDLine sensor every 24 hours.
