Re:     Hyperbaric Systems
Registration Statement on Form S-8
1,260,000 shares of Common Stock


Gentlepersons:

     We are counsel to Hyperbaric Systems, a California corporation
(the "Company").  We have assisted the Company in its preparation of
a Regitration Statement on Form S-8 (the "Registration Statement")
under the Securities Act of 1933, as amended (the "Securities Act"),
registering 1,260,000 shares of common stock of the Company (the
"Common Stock") issuable upon exercise of warrants issued by the
Company, and pursuant to a Consultant Agreement entered into by the
Company.

     In rendering this opinion, we have considered such questions of
law and examined such statutes and regulations, corporate records,
certificates and other documents and have made such other examinations,
searches and investigations as we have considered necessary.  In such
examinations we have assumed the genuineness of all signatures and the
authenticity of all documents submitted to us as originals and the
conformity to original documents of all documents submitted to us as
certified or as photocopies or telecopies.  We have not made an
independent examination of the laws of any jurisdiction other than
California and the federal laws of the United States, and we do not
express or imply any opinions in respect to the laws of any other
jurisdiction.  The opinions expressed herein are based on legislation
and regulations in effect on the date hereof.

     Based on and subject to the foregoing, we are of the opinion that
the Common Stock, when issued pursuant to the exercise of warrants
issued by the Company, and the Consultant Agreement and the purchase
price therefor has been paid, will be duly and validly issued, fully
paid and nonassessable shares of Common Stock.

     We hereby consent to the filing of this opinion as an Exhibit
to the Registration Statement.  This consent is not to be construed
as an admission that we are a person whose consent is required to be
filed with the Registration Statement under the provisions of the
Securities Act.

                             Very truly yours,

                         /s/ SILICON VALLEY LAW GROUP
