       Schedule 13D/A filed May 1, 2023

       General

   1.                                                   Your Schedule 13D
states that the funds to acquire the Common Stock were    derived
                                                        from the capital of the
Politan Funds.    If any part of the purchase price was represented
                                                        by funds or other
consideration borrowed or otherwise obtained for the purpose of
                                                        acquiring, holding,
trading or voting the Common Stock, revise the Schedule 13D to
                                                        provide a description
of the transaction(s) and the names of the parties thereto. Refer to
                                                        Item 3 of Schedule 13D.
In this regard, we refer to the article entitled    Partnering With
                                                        the Next Wave of
Activists    (May 17, 2022) available on the LinkedIn page of EnTrust
                                                        Global Partners LLC.
The article refers to the fact that Politan has raised capital on a
                                                        deal-by-deal basis and
refers to the relationship between EnTrust and Politan as one of
                                                           investment partners
with whom we have recently launched activist campaigns.

2.       Refer to comment one above. Please provide us with a legal analysis
regarding whether
         the persons named in Item 2 of the Schedule 13D have entered into
contracts,
         arrangements, understandings or relationships (legal or otherwise)
with Dennis
         Washington or EnTrust Global Partners LLC (or their respective
affiliates) with respect to
         any securities of Masimo Corporation. Refer to Item 6 of Schedule 13D
(which, if
         determined to be further applicable in the context of Politan   s
association with these
         parties, would require disclosure of, for example, contracts,
arrangements, understandings,
         or relationships involving the division of profits or loss on any
joint investment or the
         giving and withholding of proxies).
3.       Refer to comments one and two above. File as exhibits any written
agreements, contracts,
         arrangements, understanding, plans or proposals referenced in Item 7
of Schedule 13D,
         including the agreements underlying the Physically Settled Swaps and
Cash Settled
         Swaps.
4.       Please explain how you determined that EnTrust Global Partners LLC and
Politan (or
         their respective affiliates) have not formed a group under Section
13(d)(3) of the
         Exchange Act. Provide the same analysis as to Dennis Washington and
Politan.
        We remind you that the filing persons are responsible for the accuracy
and adequacy of
their disclosures, notwithstanding any review, comments, action or absence of
action by the staff.
