On April 8, 2020, HHS contracted with DuPont for 2.25 million Tyvek suits to be delivered to the SNS to be used as PPE for frontline healthcare workers. By April 13, 2020, HHS used the Defense Production Act (DPA) to contract for ventilator production with General Electric, Hill-Rom, Medtronic, ResMed, and Vyaire. Additionally, they contracted with Hamilton and Zoll for ventilator production without using the DPA. The seven contracts are expected to produce 137,431 ventilators by the end of 2020 at a total cost of $1.435 billion.
