                               ___________________


          This Proxy Statement is furnished in connection with the solicitation
by the Board of Directors of CAS Medical Systems, Inc., a Delaware corporation
(the "Company"), of proxies for use at the Annual Meeting of Stockholders of the
Company (the "Meeting") to be held on Wednesday, June 15, 2005, at 10:00 a.m.
Eastern Daylight Time, at the offices of the Company, 44 East Industrial Road,
Branford, Connecticut 06405, and at any and all postponements or adjournments
thereof, for the purposes set forth in the accompanying Notice of Annual
Meeting.

          This Proxy Statement, Notice of Annual Meeting and accompanying proxy
card are first being mailed to stockholders on or about May 4, 2005.

                                     GENERAL

          Proxies duly executed and received will be voted on all matters
presented at the Meeting in accordance with the instructions given by the person
executing such proxy or, in the absence of specific instructions, will be voted
in favor of election to the Board of Directors of the four (4) candidates
nominated by the board and in favor of the other proposals indicated on the
proxy. Management does not know of any other matter which may be brought before
the Meeting, but in the event that any other matter should properly come before
the Meeting or any nominee should not be available for election, the persons
named as proxies will have authority to vote all proxies not marked to the
contrary in their discretion as they deem advisable. Any stockholder may revoke
his or her proxy at any time before the Meeting by written notice to such effect
received by the Company at the address shown above, Attention: Corporate
Secretary, by delivery of a subsequently dated proxy, or by attending the
Meeting and voting in person.

          The Common Stock is the only class of security entitled to vote at the
meeting, each share being entitled to one vote. The total number of shares of
Common Stock outstanding as of April 22, 2005, the record date established by
the Company's Board of Directors for stockholders entitled to notice of the
Meeting and to vote at the Meeting, were 9,891,494. A majority of the issued and
outstanding shares of Common Stock, or 4,945,748 shares, must be present at the
Meeting in person or by proxy in order to constitute a quorum for the
transaction of business. Assuming the presence of a quorum, the affirmative vote
of a majority of the shares present and entitled to vote on the matter at the
Meeting is required to approve each of the matters presented.

          A list of stockholders entitled to vote at the Meeting will be
available for examination by any stockholder at the Company's offices, 44 East
Industrial Road, Branford, Connecticut 06405, for a period of ten days prior to
the Meeting and at the Meeting itself.

         Proxies will be solicited chiefly by mail. The Company will make
arrangements with brokerage houses and other custodians, nominees and
fiduciaries to send proxies and proxy material to the beneficial owners of the
shares and will reimburse them for their expenses in so doing. Should it appear
desirable to do so in order to ensure adequate representation of shares at the
meeting, the Company's officers, agents and employees may communicate with
stockholders, banks, brokerage houses and others by telephone, e-mail,
facsimile, or in person to request that proxies be furnished. The Company will
pay all expenses incurred in connection with this solicitation.

MEETINGS OF THE BOARD OF DIRECTORS

          During the Company's fiscal year ended December 31, 2004, the Board of
Directors held three meetings and acted three times by unanimous written
consent. Each director attended at least 75% of the meetings of the Board of
Directors held and of all committees of the Board of Directors on which he
served while he was director or a member of a committee of the Board of
Directors.

         We have not established a formal policy regarding director attendance
at our annual meetings of stockholders, but our directors generally do attend
the annual meeting. The Board of Directors holds one of its regular meetings in
conjunction with the annual meeting of stockholders. Accordingly, unless one or
more members of the Board are unable to attend, all members of the Board are
present for the annual meeting. All of the four members of the Board at the time
of the Company's 2004 Annual Meeting of Stockholders attended that meeting.

COMMITTEES OF THE BOARD

          The Board has standing Compensation and Audit Committees.

          COMPENSATION COMMITTEE. The Compensation Committee, composed of
Messrs. Burstein, Baron and Dr. Milles, met twice during the year ended December
31, 2004. Its functions are to review the Company's general compensation
strategy; establish salaries and review benefit programs, and certain other
compensation plans; administer our equity compensation plans; and approve
certain employment contracts.

          AUDIT COMMITTEE. The Audit Committee, composed of Messrs. Burstein,
Baron and Dr. Milles, met five times during the year ended December 31, 2004.
Its primary responsibilities are to insure directors, regulators and
shareholders that the Company's financial accounting and reporting practices and
its business controls are adequate and effective and that the Company is
complying with applicable related rules and regulations. The Audit Committee is
directly responsible for the appointment, compensation and oversight of the
audit and related work of our independent auditors. The Audit Committee reviews
the degree of their independence; approves the scope of the audit engagement,
including the cost of the audit; approves any non-audit services rendered by the
auditors and the fees for these services; reviews with the auditors and
management our policies and procedures with respect to internal accounting and
financial controls and, upon completion of an audit, the results of the audit
engagement; and reviews internal accounting and auditing procedures with our
financial staff and the extent to which recommendations made by the independent
auditors have been implemented.

          The Audit Committee does not have a written charter. All members of
the Audit Committee are independent as defined in the listing standards of the
Nasdaq Stock Market. The Board of Directors has determined that Messrs Baron and
Burstein are each an "audit committee financial expert" as that term is defined
in Item 401(e) of Regulation S-B of the Securities and Exchange Commission.

NOMINATION OF DIRECTORS

          Due to the small size of the Company's Board of Directors, the Board
of Directors determined that it is appropriate for the full Board to act with
respect to director nomination matters. Three of the four Board members are
independent as set forth in the rules of the Nasdaq Stock Market. The full Board
has adopted specifications applicable to members of the Board of Directors, and
nominees for the Board of Directors recommended by the Board of Directors must
meet these specifications. The specifications provide that a candidate for
director should:

     o    Have a reputation for industry, integrity, honesty, candor, fairness
          and discretion;

     o    Be an acknowledged expert in his or her chosen field of endeavor,
          which area of expertise should have some relevance to our businesses;

                                        5


     o    Be knowledgeable, or willing and able to become so quickly, in the
          critical aspects of our businesses and operations; and

     o    Be experienced and skillful in serving as a competent overseer of, and
          trusted advisor to, senior management of a publicly held corporation.

          In addition, nominees for the Board of Directors should contribute to
the mix of skills, core competencies and qualifications of the Board through
expertise in one or more of the following areas: accounting and finance, the
healthcare industry, international business, mergers and acquisitions,
leadership, business and management, strategic planning, government relations,
investor relations, executive leadership development, and executive
compensation.

          The Board of Directors will consider nominees recommended by
stockholders for election at the 2006 Annual Meeting of Stockholders that are
submitted prior to the end of 2005 to our Secretary at CAS Medical Systems'
offices, 44 East Industrial Road, Branford, Connecticut 06405. Any
recommendation must be in writing and must include a detailed description of the
business experience and other qualifications of the recommended nominee as well
as the signed consent of the nominee to serve if nominated and elected, so that
the candidate may be properly considered. All stockholder recommendations will
be reviewed in the same manner as other potential candidates for Board
membership.

          The Board of Directors has not received any nominees for election to
the Board from any stockholder or group that has held more than 5% of our Common
Stock for a period of one year.

COMMUNICATIONS WITH DIRECTORS

          In order to provide our security holders and other interested parties
with an open line of communication to the Board of Directors, the Board of
Directors has adopted the following procedures for communications to directors.
CAS Medical Systems, Inc security holders and other interested persons may
communicate with the chairmen of the Company's Board committees or with the
non-management directors of the Company as a group by written correspondence to
our Secretary. The correspondence should specify which of the foregoing is the
intended recipient.

          All communications received in accordance with these procedures will
be reviewed initially by our Secretary. He shall relay all such communications
to the appropriate director or directors unless he determines that the
communication:

     o    does not relate to the business or affairs of CAS Medical Systems,
          Inc. or the functioning or constitution of the Board of Directors or
          any of its committees;

     o    relates to routine or insignificant matters that do not warrant the
          attention of the Board of Directors;

     o    is an advertisement or other commercial solicitation or communication;

     o    is frivolous or offensive; or

     o    is otherwise not appropriate for delivery to directors.

          The director or directors who receive any such communication will have
discretion to determine whether the subject matter of the communication should
be brought to the attention of the full Board of Directors or one or more of its
committees and whether any response to the person sending the communication is
appropriate. Any such response will be made only in accordance with applicable
law and regulations relating to the disclosure of information.

          Our Secretary will retain copies of all communications received
pursuant to these procedures for a period of at least one year. The Board of
Directors will review the effectiveness of these procedures from time to time
and, if appropriate, recommend changes.

EMPLOYMENT CONTRACTS AND TERMINATION BENEFITS

          The Company and Mr. Scheps have entered into an employment agreement
pursuant to which Mr. Scheps serves as President and Chief Executive Officer of
the Company. As of September 1, 2004, the employment agreement was amended (as
amended, the "Employment Agreement") to extend its term through August 31, 2005
and provide for a base salary of $262,500 per year. The Employment Agreement
also provides that if a "Change of Control" (as defined below) occurs, and upon
such Change of Control occurring, the Employment Agreement is not extended for a
period of at least one year following the stated termination date of the
Employment Agreement, then Mr. Scheps shall be paid a lump sum of $250,000 on
such stated termination date. "Change of Control" is defined in the Employment
Agreement to mean (i) a sale of all or substantially all of the Company's
assets, (ii) a merger involving the Company in which the Company is not the
survivor and the Company's stockholders prior to the merger control less than
fifty percent of the voting stock of the surviving entity, (iii) a sale by the
Company's stockholders to an acquiror or acquirors acting in concert of more
than a majority of the then outstanding stock of the Company owned by the
Company's stockholders, or (iv) any event similar to any of the foregoing.
During October 1998, Mr. Scheps was granted a warrant to purchase 100,000 shares
of the Company Common Stock at an exercise price of $1.00 per share. This
warrant is exercisable solely in the event of a Change of Control.


COMPENSATION OF DIRECTORS

          During 2004, the Company paid an annual fee of $10,000 to each of the
Directors, other than those also serving as officers, and paid no other fee for
attendance at Board or committee meetings. On March 29, 2004, each non-employee
director of the Company was awarded a warrant to purchase 7,500 shares of
Company common stock at an exercise price of $1.44 per share. The warrants have
no expiration date.



                                   MANAGEMENT

          The following table sets forth the names and positions of the

          ----------------------------------------------------------------------
          Louis P. Scheps            President, Chairman of the Board, and

          Jeffery A. Baird           Chief Financial Officer & Secretary
          Andrew E. Kersey           Chief Operating Officer

                                        8


          Louis P. Scheps, 73, was appointed President and CEO of the Company in
September 1990. He had held the position of Director of Manufacturing since
1986. Prior thereto, Mr. Scheps was employed by Posi-Seal International as Vice
President from 1969 to 1985. Mr. Scheps received his engineering degree from
Purdue University and his business education from the GE Management Program.

          Jeffery A. Baird, 51, joined the Company during January 2004. From
April 2003 to December 2003, Mr. Baird was CFO of QDx, Inc., a startup venture
engaged in the development of novel medical diagnostic products. Mr. Baird was
employed by Novametrix Medical Systems, Inc. from 1988 to 2002 and held various
positions including Controller, Treasurer and CFO. Prior to joining Novametrix,
Mr. Baird was employed by Philips Medical Systems, Inc., a medical diagnostic
imaging company.

          Andrew E. Kersey, 44, was named Chief Operating Officer during January
2004. Prior to that date, Mr. Kersey held the position of Director of
Engineering since joining the Company during October 2001. Mr. Kersey was
employed by Novametrix Medical Systems as OEM Engineering Manager between 1997
and 2001 and between 1985 and 1996 in various engineering capacities. From 1996
to 1997, Mr. Kersey was employed by Corometrics Medical Systems, a division of
GE Marquette Medical as Engineering Manager.


SECTION 16 (A)  BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

          Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's executive officers and directors, and persons who beneficially own
more than ten percent of the Company's Common Stock, to file initial reports of
ownership and reports of changes in ownership with the SEC. Executive officers,
directors and greater than ten percent beneficial owners are required by the SEC
to furnish the Company with copies of all Section 16(a) forms they file.

          Based upon a review of the copies of such forms furnished to the
Company and written representations from the Company's executive officers and
directors, the Company believes that during fiscal 2004 all Section 16(a) filing
requirements applicable to its executive officers, directors and greater than
ten percent beneficial owners were complied with, except that Messrs. Baird and
Kersey each failed to file Form 4 on a timely basis with respect to an option
grant.


           ITEM 2 - RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

          Unless otherwise instructed, the persons named in the enclosed proxy
intend to vote the same in favor of the ratification of the selection by the
Audit Committee of UHY LLP ("UHY") to serve as the Company's independent
auditors for the fiscal year ending December 31, 2005. That firm has reported to
the Company that none of its members has any direct financial interest or
material indirect financial interest in the Company or any of its subsidiaries,
nor has any member of such firm had any such connection during the past three
years.

          UHY has a continuing relationship with UHY Advisors, Inc. ("Advisors")
from which it leases staff who are full time permanent employees of Advisors and
through which its partners provide non-audit services. There were no non-audit
services provided to the Company in 2004. As a result of UHY's arrangement with
Advisors, UHY has no full time employees and, therefore, all audit services
performed for the Company by UHY for 2004 were provided by permanent, full time
employees of Advisors leased to UHY. UHY manages and supervises the audit
engagement and the audit staff, and is exclusively responsible for the report
rendered in connection with its audit of the Company's 2004 consolidated
financial statements.

          A representative from UHY is expected to attend the Meeting and will
be afforded the opportunity to make a statement or respond to appropriate
questions from stockholders or both.

          Stockholder ratification of the selection of UHY as our independent
auditors is not required by our Bylaws or otherwise. However, the Audit
Committee is submitting the selection of UHY to the stockholders for
ratification as a matter of good corporate practice. If the stockholders fail to
ratify the selection, the Audit Committee will reconsider whether or not to
retain that firm. Even if the selection were ratified, the Audit Committee in
its discretion may direct the appointment of a different independent accounting
firm at any time during the year if the Audit Committee determines that such a
change would be in the best interests of the Company and its stockholders.

          On October 7, 2004, the Board of Directors and the Audit Committee
dismissed PricewaterhouseCoopers LLP ("PWC"), as the Company's independent
public accountants and engaged UHY to serve as the Company's independent public
accountants for the remainder of fiscal year 2004.

                                        9


          PWC's reports on the Company's financial statements for the year ended
December 31, 2003 did not contain an adverse opinion or disclaimer of opinion,
nor were they qualified or modified as to uncertainty, audit scope or accounting
principles.

          During the year ended December 31, 2003 and through the date of
dismissal of PWC, there were no disagreements with PWC on any matter of
accounting principles or practices, financial statement disclosure, or auditing
scope or procedure which, if not resolved to PWC satisfaction, would have caused
them to make reference to the subject matter in connection with their report on
the Company's consolidated financial statements for such years; and there were
no reportable events, as listed in Item 304(a)(1)(B) of Regulation S-B.

          The Company provided PWC with a copy of the foregoing disclosures. PWC
provided a letter, dated October 12, 2004, stating its agreement with such
statements. During the year ended December 31, 2003 and through the date of the
Audit Committee's decision, the Company did not consult PricewaterhouseCoopers
LLP with respect to 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 Company's consolidated financial statements, or any
other matters or reportable events listed in Items 304(a)(2)(i) and (ii) of
Regulation S-B.

          The Board of Directors recommends that stockholders vote "FOR"
ratification of the appointment of UHY as the Company's independent auditors for
the year 2005.

REPORT OF THE AUDIT COMMITTEE

          The Audit Committee reviews the CAS Medical Systems financial
reporting process on behalf of the Board of Directors. Management has the
primary responsibility for the financial statements and the reporting process.
The Company's independent auditors are responsible for expressing an opinion on
the conformity of its audited financial statements to generally accepted
accounting principles.

          In this context, the Audit Committee has reviewed and discussed with
management and the independent auditors the audited financial statements for the
fiscal year ended December 31, 2004. The Audit Committee has discussed with the
independent auditors the matters required to be discussed by Statement on
Auditing Standards No. 61 (Communication with Audit Committees). In addition,
the Audit Committee has received from the independent auditors the written
disclosures required by Independence Standards Board No. 1 (Independence
Discussions with Audit Committees) and discussed with them their independence
from CAS Medical Systems, Inc. and its management. The Audit Committee has also
considered whether the independent auditors provision of non-audit services to
CAS Medical Systems, Inc. is compatible with the auditor's independence.

          In reliance on the reviews and discussions referred to above, the
Audit Committee recommended to the Board of Directors, and the Board has
approved, that the audited financial statements for the fiscal year ended
December 31, 2004 be included for filing in CAS Medical Systems, Inc.'s annual
report on SEC Form 10-KSB for the year ended December 31, 2004.

          Audit Committee of the Board of Directors

          - Jerome Baron
          - Lawrence Burstein
          - Saul S. Milles, M.D.

AUDIT FEES

          Aggregate fees billed by UHY for the audit of our interim consolidated
financial statements included in a quarterly report on Form 10-QSB, for the
audit of our annual consolidated financial statements and the restatement of
prior year financial results included in the annual report on Form 10-KSB for
the year ended December 31, 2004 and for the review and audit of the application
of new accounting pronouncements and SEC releases were $81,500. Aggregate fees
billed by PWC for the review of our interim consolidated financial statements
included in quarterly reports on Form 10-QSB

                                       10


filed during 2004 for the review of other SEC filings, and for the review of the
Company's restatement of its prior year financial statements included in the
annual report on Form 10-KSB for the year ended December 31, 2004 were $61,950.

TAX FEES

          Aggregate fees billed by UHY for professional services rendered to the
Company for tax compliance, tax advice and tax planning were $14,000 for the
year ended December 31, 2004. Fees billed by PWC for such services for the year
ended December 31, 2003 was $17,600. The tax related services include primarily
federal and state income tax services.

AUDIT-RELATED FEES AND ALL OTHER FEES

          The Company did not incur any audit-related fees or other fees
pertaining to services provided by UHY or PWC for the year ended December 31,
2004 and did not incur such similar fees pertaining to services provided by PWC
for the year-ended December 31, 2003.

PRE-APPROVAL POLICIES

          The Audit Committee has adopted a policy under which certain audit,
non-audit and tax related services to be performed by the Company's independent
auditors are required to be pre-approved by the Audit Committee in order to
assure that they do not impair the auditor's independence from the Company.
Included in, but not limited to, those pre-approved services are, required
interim quarterly reviews; local, state and federal tax compliance, planning,
preparation and filing services; due diligence services pertaining to potential
business acquisitions and dispositions; accounting consultations related to
accounting, financial reporting or disclosure matters not classified as "Audit
Services"; assistance with understanding and implementing new accounting and
financial reporting guidance from rulemaking authorities; financial audits of
employee benefit plans; agreed-upon or expanded audit procedures related to
accounting and or billing records required to respond to or comply with
financial, accounting or regulatory reporting matters; and assistance with
internal control reporting requirements. All of the audit-related, tax and other
services and related fees provided by PricewaterhouseCoopers and UHY in fiscal
year 2004 were approved in advance by the Audit Committee.
