Low-Cost Portable Ventilator

A Nuvation client wanted to build a low-cost medical ventilator for use in developing countries where hospitals cannot afford to purchase many mechanical ventilators.

Nuvation worked with the client to design and build a ventilator that cost less than half the price of most mechanical ventilators on the market. We were able to achieve this by using lower cost components and a unique architecture.

A ventilator at this price point could help reduce the shortage of ventilators in hospitals and enable developing countries to provide patients with better care.
