First Claim
Patent Images
1. A method, comprising:
- controlling a ventilator to introduce mean airway pressure (MAP) variations in a patient to induce slow waves of substantially fixed amplitude and period to the patient;
analyzing arterial blood pressure in the patient with respect to the MAP variations; and
determining, based on the analyzing, whether an autoregulatory mechanism associated with the patient'"'"'s brain is operating properly.

Abstract
A method may include controlling a ventilator to introduce mean airway pressure (MAP) variations in a patient to induce slow waves of substantially fixed amplitude and period to the patient. The method may also include analyzing arterial blood pressure in the patient with respect to the MAP variations and determining, based on the analyzing, whether an autoregulatory mechanism associated with the patient'"'"'s brain is operating properly.

10. A system, comprising:
a ventilator configured to; provide ventilation functions to a subject, and provide mean airway pressure (MAP) variations to the subject to induce slow waves to the subject, wherein the slow waves have a fixed amplitude and frequency and are provided simultaneously with the ventilation functions. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A 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 ventilator to introduce mean airway pressure (MAP) variations to generate slow waves to a patient, wherein the slow waves have a fixed amplitude and frequency; analyze arterial blood pressure in the patient at a frequency corresponding to the slow wave frequency; and determine, based on the analyzing, whether an autoregulatory mechanism associated with the patient'"'"'s brain is operating properly. - View Dependent Claims (19, 20)
