Commitments and Contingencies [Text Block]	Commitments and Contingencies Legal Proceedings Beginning in November 2016, purported class actions were filed in the U.S. District Court for the Northern District of Illinois against Pfizer, Inc. subsidiaries, Hospira, Inc., Hospira Worldwide, Inc. and certain other defendants relating to the intravenous saline solutions part of the HIS business. Plaintiffs seek to represent classes consisting of all persons and entities in the U.S. who directly purchased intravenous saline solution sold by any of the defendants from January 1, 2013 until the time the defendants’ allegedly unlawful conduct ceases. Plaintiffs allege that U.S. manufacturer defendants conspired together to restrict output and artificially fix, raise, maintain and/or stabilize the prices of intravenous saline solution sold throughout the U.S. in violation of federal antitrust laws. Plaintiffs seek treble damages (for themselves and on behalf of the putative classes) and an injunction against defendants for alleged price overcharges for intravenous saline solution in the U.S. since January 1, 2013. On July 5, 2018, the District Court granted defendants’ motion to dismiss the operative complaint for failing to state a valid antitrust claim, but is allowing plaintiff to file a second amended complaint. On September 6, 2018, plaintiffs filed a second amended complaint adding new allegations in support of their conspiracy claims and adding ICU as a defendant. On February 3, 2017, we completed the acquisition of the HIS business from Pfizer. This litigation is the subject of a claim for indemnification against us by Pfizer and a cross-claim for indemnification against Pfizer by us under the HIS stock and asset purchase agreement (“SAPA”). In addition, in August 2015, the New York Attorney General issued a subpoena to Hospira, Inc. requesting that the company provide information regarding certain business practices in the intravenous solutions part of the HIS business. Separately, in April 2017, we received a grand jury subpoena issued by the United States District Court for the Eastern District of Pennsylvania, in connection with an investigation by the U.S. Department of Justice, Antitrust Division. The subpoena calls for production of documents related to the manufacturing, selling, pricing and shortages of intravenous solutions, including saline, as well as communications among market participants regarding these issues. The Department of Justice investigation is the subject of cross-claims for indemnification by both us and Pfizer under the HIS Purchase Agreement. We have coordinated with Pfizer to produce records to the New York Attorney General and the Department of Justice. In April 2018, the U.S. Department of Justice issued a HIPAA subpoena to Hospira, Inc., requesting production of documents and records regarding the manufacturing, production, testing, quality and validation of the Sapphire™ infusion pumps, sets and related accessories distributed by the Company. We are coordinating with Pfizer to produce the requested records to the Department of Justice. In March 2018, a dispute with a product partner resulted in a redefinition of our contractual arrangement and in the rights and remedies determined under such arrangement. The resolution of the dispute resulted in a $28.9 million net charge to the condensed consolidated statement of operations. From time to time, we are involved in various legal proceedings, most of which are routine litigation, in the normal course of business.
