The ventilator shortage, explained video - CNET

Ventilators are machines that deliver breaths of oxygenated air to people who are unable to breathe sufficiently on their own, while removing carbon dioxide from the lungs. There are an estimated 160,000 ventilators in the United States. That's usually enough to serve everyone that needs one, but in the case of the coronavirus pandemic, it's a severe shortage. Companies including General Motors, Ford, and Tesla are offering their help, but will that help come in time?
