Abstract
We report a method of determining an occurrence of an epileptic convulsive seizure in a patient, comprising: receiving body data from a patient during a first time period, determining a work level relating to said first time period at least based partially upon said body data; determining whether said work level exceeds an extreme work level threshold; performing a responsive action, in response to a determination that said work level exceeds said extreme work level threshold. We also report a medical device system configured to implement the method. We also report a non-transitory computer readable program storage unit encoded with instructions that, when executed by a computer, perform the method.
Claims32
A non-transitory computer readable program storage unit encoded with instructions that, when executed by a computer, perform a method of determining an occurrence of an epileptic convulsive seizure in a patient, comprising:
- receiving body data from a patient during a first time period,
- determining a work level relating to said first time period at least based partially upon said body data;
- determining whether said work level exceeds an extreme work level threshold;
- detecting said extreme event in the patient responsive to determining that said work level exceeds said extreme work level threshold;
- classifying said extreme event as an epileptic convulsive seizure;
- performing a responsive action comprising:
- issuing a warning of said detection;
- delivering a therapy;
- determining a severity of said detection of the epileptic convulsive seizure;
- and
- logging to memory one or more of:
- at least one of a date, a time, or a severity of said detected epileptic convulsive seizure;
- a type of therapy delivered to treat said epileptic convulsive seizure;
- or
- at least one effect of a therapy delivered to treat the epileptic convulsive seizure.
A medical device, comprising:
- a body data module configured to receive body data;
- a work level data module configured to determine a first patient work level during a first time period, and a second patient work level during a second time period;
- a work level excursion module configured to:
- determine whether said second work level exceeds said first work level by an amount greater than a first work level excursion threshold;
- and
- detect a work level excursion based upon a determination that said second work level exceeds said first work level by an amount greater than said first work level excursion threshold;
- and
- a controller to perform at least one of warning of said work level excursion, providing a therapy for said work level excursion, or logging an occurrence of said work level excursion, in response to detecting said work level excursion.
A non-transitory computer readable program storage unit encoded with instructions that, when executed by a computer, perform a method of determining a work level of a subject's brain, comprising:
- determining a first oxygen saturation, oxygen concentration, or oxygen pressure of the subject's blood at a first location in a carotid artery;
- determining a second oxygen saturation, oxygen concentration, or oxygen pressure of the subject's blood at a second location in a jugular vein;
- and
- determining the work level of the subject's brain based on the first oxygen saturation, oxygen concentration, or oxygen pressure and the second oxygen saturation, oxygen concentration, or oxygen pressure.
A medical device system for determining a metabolic work level of a subject, comprising:
- a first sensor configured to collect first oxygen saturation, oxygen concentration, or oxygen pressure data of a subject's blood from a first location in a carotid artery;
- a second sensor configured to collect second oxygen saturation, oxygen concentration, or oxygen pressure data of the subject's blood from a second location in a jugular vein;
- and
- a medical device, comprising:
- a first location oxygen saturation, oxygen concentration, or oxygen pressure module configured to determine a first oxygen saturation, oxygen concentration, or pressure from said first oxygen saturation, concentration, or pressure data;
- a second location oxygen saturation, oxygen concentration, or oxygen pressure module configured to determine a second oxygen saturation, oxygen concentration, or oxygen pressure from said second oxygen saturation, oxygen concentration, or oxygen pressure data;
- and
- a brain work level determination module configured to determine a work level of the subject's brain based on the first oxygen saturation, oxygen concentration, or oxygen pressure and the second oxygen saturation, oxygen concentration, or oxygen pressure.
