'Production of 3D printed components for ventilation systems: practical hints'
Notes from the front lines in Italy:

'The current emergency allows exceptions to the use of not certified medical devices, if it is proved
that no certified choices are available and in accordance with the local ethical committee.
Furthermore, due to the short time required for the production, it is not possible to run extensive
testing campaigns on the components, but each [additive manufacturing] operator must pay attention to the selection of
materials and technologies that are suitable for the specific application, considering the risk
classification of the components and the operational environment.
In the following we summarize the workflow we applied at 3D4Med (http://www.3d4med.eu) – the
Clinical 3D Printing Laboratory of San Matteo Hospital in Pavia – and Protolab – its engineering
counterpart – to produce some of the requested components, along with some practical examples.'

Medtronic releases PB560 Ventilator Design and Manufacturing docs
Schematics, manuals, manufacturing docs for the Medtronic PB560 ventilator, released under a permissive license. Awesome stuff.

'We appreciate your interest in using the design specifications for the Medtronic PB560 ventilator system to help address the shortage of ventilators due to the COVID-19 pandemic. We invite manufacturers, engineers, and other innovators to use these files as inspiration for their own innovations.'

Rapidly manufactured ventilator system specification - GOV.UK
This is a specification of the minimally (and some preferred options) clinically acceptable ventilator to be used in UK hospitals during the current SARS-CoV2 outbreak. It sets out the clinical requirements based on the consensus of what is ‘minimally acceptable’ performance in the opinion of the anaesthesia and intensive care medicine professionals and medical device regulators.

It is for devices, which are most likely to confer therapeutic benefit on a patient suffering with ARDS caused by COVID-19, used in the initial care of patients requiring urgent ventilation. A ventilator with lower specifications than this is likely to provide no clinical benefit and might lead to increased harm, which would be unacceptable for clinicians and would, therefore, not gain regulatory approval.

Specifications for simple open source mechanical ventilator
from Julian Botta, Johns Hopkins Emergency Medicine Resident PGY-3 , Twitter: @julianbotta

'This is a living document intended to give non-clinicians/non-respiratory therapists an idea of key ventilator features and one proposed simplified design. I encourage other healthcare professionals who are very familiar with ventilators and their use to give me feedback using the comments feature to improve these specifications.'

low-cost mechanical ventilator prototype
a team of students from MIT has devised a better way to keep patients breathing in places that lack standard mechanical ventilators, or during times of emergency such as pandemics or natural disasters, when normal hospital resources may be overextended. They have designed a system that uses the same widely available manual pump — the same type used for the farmer in India. The new system encases the pump in a plastic box with a battery, motor and controls to take the place of the manual compression process.


This article from 2010 notes 'a U.S. government study in 2005 found that in a worst-case pandemic scenario, this country alone might need more than 700,000 mechanical ventilators, while only 100,000 are now in use.'
