Patient sedation monitor
First Claim
1. A system for determining a patient'"'"'s level of sedation, said system comprising a) a glabellar stimulator constructed to generate an electrical stimulus;
- b) an electrode electrically connected to said glabellar stimulator, said electrode constructed to deliver said electrical stimulus from said glabellar stimulator to a patient; and
c) a patient module constructed to detect an eyeblink response of a patient following delivery of said electrical stimulus to the patient, said patient module constructed to generate a signal indicative of at least one parameter of said eyeblink response, wherein said at least one parameter of said eyeblink response is indicative of a patient'"'"'s level of sedation.

Abstract
A system for determining a patient'"'"'s level of sedation. The system includes a glabellar stimulator constructed to generate an electrical stimulus. An electrode is electrically connected to the glabellar stimulator, the electrode being constructed to deliver the electrical stimulus from the glabellar stimulator to a patient. The system further includes a patient module constructed to detect an eyeblink response of a patient following delivery of the electrical stimulus to the patient. The patient module is constructed to generate a signal indicative of at least one parameter of the eyeblink response, wherein the at least one parameter of the eyeblink response is indicative of a patient'"'"'s level of sedation.

7. A system for determining a patient'"'"'s level of sedation, comprising:
-
a) a stimulus generating circuit constructed to generate a charge neutral stimulus;
b) an electrode array comprising a plurality of electrodes, at least one of said plurality of electrodes electrically connected to said stimulus generating circuit and constructed to deliver said charge neutral stimulus to a patient;
c) a system constructed to receive and analyze one or more neurophysiological signals from a patient following delivery of said charge neutral stimulus to the patient, said system generating a parameter characteristic of a patient'"'"'s level of sedation based upon said one or more neurophysiological signals. - View Dependent Claims (8, 9)

10. A system for differentiating between natural sleep and sedation in a patient in a drug induced hypnotic state, comprising:
-
a) a circuit constructed to generate a substantially charge neutral electrical stimulus;
b) at least one electrode electrically connected to said circuit, said at least one electrode constructed to deliver said substantially charge neutral electrical stimulus from said circuit to a patient;
c) at least one electrode constructed to detect one or more neurophysiological signals from a patient that are generated in response to said substantially charge neutral electrical stimulus; and
d) a module constructed to receive from said at least one electrode and analyze said one or more neurophysiological signals, said module constructed to produce one or more parameters representative of a patient'"'"'s state of sedation.
