But what federal officials have neglected to mention is that an additional 2,109 lifesaving devices are unavailable after the contract to maintain the government’s stockpile lapsed late last summer, and a contracting dispute meant that a new firm did not begin its work until late January. By then, the coronavirus crisis was already underway.

The revelation came in response to inquiries to the Department of Health and Human Services after state officials reported that some of the ventilators they received were not operational, stoking speculation that the administration had not kept up with the task of maintaining the stockpile.

In fact, the contract with a company that was maintaining the machines expired at the end of last summer, and a contract protest delayed handing the job to Agiliti, a Minneapolis-based provider of medical equipment services and maintenance. Agiliti was not given the $38 million task until late January, when the scope of the global coronavirus crisis was first becoming clear.
