under Rule 144 under the Securities Act of 1933;
       (2)  do and perform any and all acts for and on behalf of the

        (3)  take any other action of any type whatsoever in connection
with the foregoing which, in the opinion of such attorney in fact, may

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,

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

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 February 27, 2023.
