Abstract
An apparatus for reversing inhaled anesthesia, which may be configured to be positioned along a breathing circuit or anesthesia delivery circuit, includes an anesthesia removal component and a blood flow acceleration component. The blood flow acceleration component facilitates an increase in the ventilation of the individual without resulting in a significant decrease in the individual's PaCO2 level and, thus, a decrease in the rate at which blood flows through the individual's brain. A method of reversing the effects of inhaled anesthesia includes increasing the rate of ventilation of an anesthetized individual while causing the individual to inhale gases with at least atmospheric amounts of CO2.
Claims20
A method for facilitating emergence of a subject from inhaled anesthesia, comprising:
- decreasing a concentration of anesthesia in blood leaving the lungs and flowing into the brain of the subject with at least one anesthesia reversal apparatus;
- and
- increasing blood flow through the brain of the subject with the at least one anesthesia reversal apparatus.
A system for facilitating emergence of a subject from inhaled anesthesia, comprising:
- an anesthesia removal component for decreasing concentration of anesthesia in blood leaving the lungs and flowing into the brain of the subject;
- and
- a blood flow acceleration component for increasing blood flow through the brain of the subject.
A method for facilitating emergence of a subject from inhaled anesthesia, comprising:
- increasing ventilation of the subject with an anesthesia reversal system;
- and
- causing the subject to inhale gases including at least an atmospheric amount of carbon dioxide with the anesthesia reversal system.
