As the number of confirmed coronavirus cases in the U.S. has topped 100,000, a Californian company is pulling out all the stops to deliver slimmed-down ventilators that can meet the needs of about 90 percent of all critical care patients.

Medical device engineering firm Nectar Inc. launched BreathDirect to make the new, simpler devices at a cost of 10,000 U.S. dollars per unit. The team's goal is to produce 3,500 ventilators per week in May and 40,000 ventilators per month by June.
