Forms 4 and 5 in accordance with Section 16(a) of the Securities Exchange

the Securities Act of 1933;
       (2)  do and perform any and all acts for and on behalf of the

amendments thereto, and timely file any such form with the United States
Securities and Exchange Commission and any stock exchange or similar
authority; and
        (3)  take any other action of any type whatsoever in connection
with the foregoing which, in the opinion of such attorney in fact, may
be of benefit to, in the best interest of, or legally required by, the
undersigned, it being understood that the documents executed by such
attorney in fact on behalf of the undersigned pursuant to this Power of
Attorney shall be in such form and shall contain such terms and
conditions as such attorney in fact may approve in such attorney in
fact's discretion.
The undersigned hereby grants to each such attorney in fact full power
and authority to do and perform any and every act and thing whatsoever
requisite, necessary, or proper to be done in the exercise of any of
the rights and powers herein granted, as fully to all intents and
purposes as the undersigned might or could do if personally present,

confirming all that such attorney in fact, or such attorney in fact's
substitute or substitutes, shall lawfully do or cause or have caused
to be done by virtue of this power of attorney and the rights and
powers herein granted. The undersigned acknowledges that the foregoing

Securities Exchange Act of 1934 and Rule 144 of the Securities Act
of 1933.
This Power of Attorney shall super cede any power of attorney
previously granted by the undersigned with respect to the subject
matter herein and shall remain in full force and effect until the
undersigned is no longer required to file Forms 4, 5 and 144 with
respect to the undersigned's holdings of, and transactions in,
securities issued by Baxter, unless earlier revoked by the
undersigned in a signed document delivered to Baxter.

       IN WITNESS WHEREOF, the undersigned has caused this Power of
Attorney to be executed as of May 2, 2022.
