The EEG electrode locator headgear allows the user to locate and apply disposable EEG electrodes accurately according to the International 10/20 System without technical assistance, to allow the acquisition of high quality EEG signals. The headgear includes a front forehead pad, a base strap assembly connected to the front forehead pad, a plurality of EEG electrode locators for receiving EEG electrodes, and a plurality of locator straps connected to the front pad of material, the base strap assembly, and to the plurality of EEG electrode locators for accurately positioning the plurality of EEG electrode locators positioned relative to the scalp of a user. A visor can be attached to the front pad of material, and the base strap assembly may include an occipital locator device. A plunger assembly with spreadable fingers for optionally parting the hair of the users scalp is also provided that is inserted in the electrode locators to optionally prepare the users scalp and to seat the electrodes. In one embodiment, a spreader portion of the plunger assembly is formed of electrically conductive material, such as electrically conductive silicone.

The method for the quantification of EEG waveforms along the alertness continuum involves collecting and transforming EEG signal data, identifying and rejecting or decontaminating epochs containing various artifacts, and classifying individual EEG patterns along an alertness-drowsiness continuum. The results of the multi-level classification system are applied in real-time to provide feedback to the user via an audio or visual alarm, or are recorded for subsequent off-line analysis.

The EEG electrode and EEG electrode locator assembly may be used in combination with an EEG electrode locator headgear including a plurality of locator straps connectable to one or more of the EEG electrode locators that form an electrode locator assembly with the EEG electrode, for accurately positioning one or more of the EEG electrodes relative to the users scalp, and for biasing the plurality of electrodes toward the users scalp. The EEG electrode is adapted to be received in and cooperate with an EEG electrode locator ring, to form the electrode locator assembly. The EEG electrode includes a dispenser assembly adapted to dispense an electrically conductive gel onto the users scalp to prepare the users scalp. The dispenser assembly includes a base member and a porous foam pad lower cover to provide padding for a comfortable scalp interface, absorbs the conductive gel to maintain a consistent volume of gel between the electrode base and scalp, and for conducting EEG signals from the scalp of the user to a corresponding electrode locator ring for communication to an EEG monitor.

In a technique for collecting and analyzing physiological signals to detect sleep apnea, a small light-weight physiological monitoring system, affixed to a patients forehead, detects and records the pulse, oximetry, snoring sounds, and head position of a patient to detect a respiratory event, such as sleep apnea. The physiological monitoring system may contain several sensors including a pulse oximeter to detect oximetry and pulse rate, a microphone to detect snoring sounds, and a position sensor to detect head position. The physiological monitoring system also can contain a memory to store or record the signals monitored by the mentioned sensors and a power source. The physiological monitoring system may be held in place by a single elastic strap, thereby enabling a patient to use the system without the assistance of trained technicians.

Photoplethysmography (PPG) is obtained using one red (e. g. , 660 nm) and one infrared (e. g. , 880 to 940 nm) light emitting diode with a single photo diode in combination with a pressure transducer thereby allowing both CVP and SpO2 to be measured simultaneously. The system also includes sensors capable of measuring position, angle and/or movement of the sensor or patient. Once the PPG signal is acquired, high pass adaptive and/or notch filtering can be used with one element of the filter from the red and infrared signals used to measure the arterial changes needed to compute SpO2 and the other element of the signal can be used to measure CVP changes.
