Systems for removing dimethyl sulfoxide (DMSO) or related compounds, or odors associated with same

A method for reducing the undesired odor associated with one or more metabolites of DMSO, comprising:

• transporting, via a medical ventilator, DMSO metabolite-containing air comprising one or more DMSO metabolites through said medical ventilator in use by a subject that has been treated with DMSO,
• wherein said medical ventilator comprises a first filter and a HEPA filter,
• wherein said first filter further comprises an indicator compound,
• wherein the ventilator is configured to receive said DMSO metabolite-containing air,
• wherein the first filter comprises an adsorbent configured to adsorb said one or more DMSO metabolites from said DMSO metabolite-containing air,
• wherein said adsorbent comprises activated carbon, and
• capturing an amount of said one or more DMSO metabolites sufficient to reduce the associated odor by contacting said DMSO metabolite-containing air with said first filter, thereby decreasing the concentration of said one or more DMSO metabolites assin throu h said ventilator.

A method for providing air having a reduced undesired odor associated with one or more metabolites of dimethyl sulfoxide (DMSO) comprising:

• conveying air comprising one or more DMSO metabolites having an undesired odor through a clean air member comprising:
• an adsorbent configured to adsorb said one or more DMSO metabolites or the odor associated therewith;
• a pre-filter;
• and a HEPA filter, and
• trapping an amount of said one or more DMSO metabolites or the odor associated therewith sufficient to reduce the associated odor by contacting said DMSO metabolites with said adsorbent, said pre-filter, and said HEPA filter to thereby provide air having a reduced undesired odor associated with one or more metabolites of DMSO.

A method for reducing undesired odors associated with one or more metabolites of dimethyl sulfoxide (DMSO) in the vicinity of a patient that has been treated with DMSO comprising:

• positioning said patient within a patient isolation unit coupled to a clean air supply assembly, said clean air supply assembly comprising:
• a first adsorbent configured to adsorb said one or more DMSO metabolites or the odor associated therewith;
• a pre-filter;
• and
• a HEPA filter, and
• said patient isolation unit comprising an odor-absorbing fabric article comprising a second adsorbent configured to adsorb said one or more DMSO metabolites or the odor associated therewith,
• conveying DMSO metabolite-containing air from said patient through said patient isolation unit;
• reducing the concentration of said one or more DMSO metabolites sufficient to reduce the associated odor by contacting said DMSO metabolite-containing air with said first adsorbent, said pre-filter, and said HEPA filter, thereby providing air having reduced undesired odors associated with said one or more metabolites of DMSO;
• and
• positioning said odor-absorbing fabric article comprising said second adsorbent around said patient,
• wherein said odor-absorbing fabric article comprising said adsorbent further reduces said one or more DMSO metabolites or the odor associated therewith.
