I keep hearing about shortages of ventilators, parts, masks, and so on and also of companies that are rising to meet the needs to produce them.<p>However I have no idea what is actually happening in terms of what is currently being produced, by whom, and in what quantities.<p>I would like to track these and hopefully provide useful information to people to help them understand the state of the supply chain for COVID-19.<p>Any idea if this information exists and where it can be reliably found?
