Item 4.01.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT

On October 7, 2004 CAS Medical Systems, Inc. (the "Registrant") dismissed
PricewaterhouseCoopers LLP as the Registrant's Independent Registered Public
Accounting Firm and selected and engaged UHY LLP as the Registrant's Independent
Registered Public Accounting Firm for the fiscal year ending December 31, 2004.
UHY LLP advised the Registrant of its acceptance of the engagement as of October
7, 2004.

PricewaterhouseCoopers LLP's reports on the Registrant's financial statements
for the fiscal years ended December 31, 2002 and 2003 did not contain an adverse
opinion or a disclaimer of opinion, nor were they qualified or modified as to
uncertainty, audit scope or accounting principles. During the Registrant's two
fiscal years ended December 31, 2002 and 2003 and the interim period from
January 1, 2004 through October 7, 2004, there were no disagreements with
PricewaterhouseCoopers LLP on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure, which
disagreements if not resolved to PricewaterhouseCoopers LLP's satisfaction,
would have caused PricewaterhouseCoopers LLP to make reference thereto in its
reports on the financial statements for such years.

During the Registrant's two fiscal years ended December 31, 2002 and 2003 and
the interim period from January 1, 2004 through October 7, 2004, there were no
reportable events (as described in Regulation S-B Item 304 (a)(1)(iv)).

The Registrant has provided PricewaterhouseCoopers LLP with a copy of the above
statements and requested that PricewaterhouseCoopers LLP furnish it with a
letter addressed to the Securities and Exchange Commission stating whether it
agrees with the above statements and, if not, stating the respects in which it
does not agree. A copy of such letter is filed as Exhibit 16.1 to this Current
Report on Form 8-K.

During the two most recent fiscal years and through October 7, 2004, neither the
Registrant nor anyone on its behalf has consulted with UHY LLP regarding either
(i) the application of accounting principles to a specified transaction, either
completed or proposed; or the type of audit opinion that might be rendered on
the Registrant's financial statements, and neither a written report was provided
to the Registrant nor oral advice was provided by UHY LLP that was an important
factor considered by the Registrant in reaching a decision as to any accounting,
auditing or financial reporting issue; or (ii) any matter that was the subject
of a disagreement, as described in Item 304 (a)(1)(iv) of Regulation S-B and the
related instructions to Item 304 of Regulation S-B, or a reportable event, as
described in Item 304 (a)(1)(iv) of Regulation S-B and the related instructions
to Item 304 of Regulation S-B.

Item 9.01.  FINANCIAL STATEMENTS AND EXHIBITS

(c)  Exhibits - The following exhibit is furnished as part of this report:

16.1      Letter from PricewaterhouseCoopers LLP to the United States Securities
          and Exchange Commission.



                                   SIGNATURES

     Pursuant to the requirements of the Securities Exchange Act of 1934, the
Registrant has duly caused this report to be signed on its behalf by the
undersigned thereunto duly authorized.
