First Claim
Patent Images
1. A method, comprising:
- controlling a bypass pump to introduce blood flow variations to a patient;
analyzing blood volume in the brain of the patient with respect to the blood flow variations; and
determining, based on the analyzing, whether an autoregulatory mechanism associated with the brain is operating properly.

8. A system, comprising:
-
a pump controller configured to control a bypass pump to introduce blood flow variations to a patient corresponding to an input wave having a first frequency; and at least one monitoring device configured to; analyze blood volume in the brain of the patient with respect to the blood flow variations, and determine, based on the analyzed blood volume, whether an autoregulatory mechanism associated with the brain is operating properly. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable medium having stored thereon sequences of instructions which, when executed by at least one processor, cause the at least one processor to:
-
control a bypass pump to introduce blood flow variations to a patient; analyze blood volume in the brain of the patient with respect to the blood flow variations; and determine whether an autoregulatory mechanism associated with the brain is functioning properly based on the analyzing. - View Dependent Claims (16, 17, 18, 19, 20)
