Open Source Medical Device Guide

A Facebook group was setup to discuss recommendations around open-source efforts in response to COVID-19. Here is a 1.0 version of the doc they released. Most of the guidance so far is written in a way that assumes professional care is available.

Ventilator Shortage Analysis

Here we will briefly summarize information on the supply and potential shortage. Key numbers that will affect this:

1. The current numbers for supply of ventilators (# of ventilators currently)
2. The demand for ventilators, over time (# of ventilators needed over time)
3. The ability to increase supply of ventilators (# of ventilators able to be manufactured over time)

Additionally, the numbers above will vary based on each region's need globally.

Some preliminary data (we can continue to update) on some of these areas:

Region	# ventilators, current supply	# ventilators, needed
Globe
U.S.	46,000 [1]	200,000 or more [1]
California	7,587 and "buying more" now [2]
U.K.	5,000 [3]	> 30,000 [3]
... add more...	...	...
