Abstract

A method is provided for reducing the risk of sustaining a traumatic brain injury caused by a traumatic event that includes identifying a subject at risk of sustaining a traumatic brain injury, and then precisely increasing the partial pressure of carbon-dioxide (CO2) in the blood of the subject (pCO2). This method can be applied to raise the CO2 and pCO2 to improve orthostatic hypotension in conditions such as dysautonomias (like Positional Orthostatic Tachycardic Syndrome POTS) and to facilitate the drive to breathe in conditions like Central Sleep Apnea (CSA) and Sudden Infant Death Syndrome (SIDS). The pCO2 of the person is increased by placing a breathing apparatus over the mouth of the person through which the person must breath, wherein the breathing apparatus includes an enlarged dead space volume in which expired CO2 collects to be inhaled or re-breathed by the person on the next inhalation.

Claims13

Dependent claims

A breathing apparatus for increasing the partial pressure of carbon-dioxide (CO2) in the blood of a subject (pCO2), comprising:

a chamber having an opening configured to be in direct communication with the mouth of the subject and at least one outlet configured to be in direct communication with ambient air for gas to flow therethrough as the subject inhales the ambient air and exhales CO2 through said at least one outlet;
and
an enlarged dead space between said opening and each of said at least one outlet, the dead space defining a volume sized to retain a predetermined portion of the CO2 exhaled by the subject as the subject exhales through each of said at least one outlet, so that the predetermined portion is mixed within the enlarged dead space with ambient air inhaled through each of said at least one outlet by the subject on the next inhalation,
wherein the volume of the dead space is 10 to 50% of the tidal volume of air displaced by the subject during inhalation and exhalation.
