Abstract
This document provides methods and materials for treating hypocapnia. For example, methods and materials for delivering CO2 to a mammal to treat hypocapnia or compensate for a reduced level of CO2 are provided.
Claims16
A canister device for delivering breathing gas of oxygen and CO2 to a mammal, wherein said canister device comprises an oxygen module, a CO2 module, an actuator, and a mouthpiece, wherein said oxygen module comprises an oxygen gas source, wherein said CO2 module comprises a liquid compartment for housing a liquid, a solid compartment for housing a solid, said liquid, and said solid, wherein said actuator is configured to allow said liquid to contact said solid upon actuation, thereby releasing CO2 from said CO2 module, wherein said actuator is configured to release oxygen from said oxygen module upon actuation, wherein said mouthpiece is in fluid communication with a CO2 line connected to said CO2 module and an oxygen line connected to said oxygen module, and wherein actuation of said actuator releases CO2 and oxygen gas for said mammal to inhale through said mouthpiece.
A method for treating a mammal suffering from hypocapnia, wherein said method comprises delivering breathing gas of oxygen and CO2 to said mammal for said mammal to inhale through a mouthpiece of a canister device, thereby treating said hypocapnia,
- wherein said canister device comprises an oxygen module, a CO2 module, an actuator, and said mouthpiece, wherein said oxygen module comprises an oxygen gas source, wherein said CO2 module comprises a liquid compartment for housing a liquid, a solid compartment for housing a solid, said liquid, and said solid, wherein said actuator is configured to allow said liquid to contact said solid upon actuation, thereby releasing CO2 from said CO2 module, wherein said actuator is configured to release oxygen from said oxygen module upon actuation, wherein said mouthpiece is in fluid communication with a CO2 line connected to said CO2 module and an oxygen line connected to said oxygen module, and wherein actuation of said actuator releases CO2 and oxygen gas for said mammal to inhale through said mouthpiece.
