Paralleling Motor Drivers

Do  not parallel L298 brushed motor drivers because they are bipolar transistors. Paralleling may be possible however with MOSFETs.

Ventilator induced injury

From https://en.wikipedia.org/wiki/Mechanical_ventilation Risk Mechanical ventilation is often a life-saving intervention, but carries potential complications including pneumothorax , airway injury, alveolar damage, ventilator-associated pneumonia , and ventilator-associated tracheobronchitis . [4] [5] Other complications include diaphragm atrophy, decreased cardiac output, and oxygen toxicity. One of the primary complications that presents in patients mechanically ventilated is acute lung injury (ALI)/acute respiratory distress syndrome (ARDS). ALI/ARDS are recognized as significant contributors to patient morbidity and mortality. [6] In many healthcare systems, prolonged ventilation as part of intensive care is a limited resource (in that there are only so many patients that can receive care at any given moment). It is used to support a single failing organ system (the lungs) and cannot reverse any underlying disease process (such as terminal cancer). For this reason...

Medtronics released the schematics ,manufacturing jigs and cad files for their PB560 ventilator system

Forwarded from University College Cork .... In these difficult times medical devices such as ventilators/respirators are in very high demand. Please help us in mobilizing and facilitating production of these devices that are (or could become) desperately needed in hospitals throughout the world to save lives. Based on global high demand of ventilators and respirators, Medtronic made available plans to facilitate production of ventilators. In this interview, Omar Ishrak (Medtronic CEO), tells a great deal about different grades of ventilators, how production is being increased, and where they are going: https://www.cnbc.com/video/ 2020/03/25/medtronic-ceo-omar- ishrak-on-ramping-up- ventilator-production.html In case you know factories and/or students that want a COVID-related project, they can download the plans for this Ventilator and produce them: https://www.medtronic.com/us- en/e/open-files.html?cmpid= vanity_url_medtronic_com_ openventilator_Corp_US_ Co...

OP-Vent

https://op-vent.stanford.edu/ A different take: without an ambu bag. Claims: A mechanical ventilator design developed by Dally can be assembled quickly, using off-the-shelf parts with a total cost of around $400 — making it an accessible and affordable alternative to traditional, dedicated ventilators, which can cost $20,000 or more. Includes just two central components — a solenoid valve and a microcontroller. The design is called the OP-Vent , and in the video below you can see how bare-bones it is in terms of hardware compared to existing alternatives, including some of the other more complex emergency-use ventilator designs developed in response to COVID-19. Has been developed using input from mechanical engineers and doctors, including Dr. Andrew Moore, a chief resident at Stanford University and Dr. Bryant Lin, a medical devices expert and company co-founder. Can be assembled in as little as five minutes, and is small enough to fit in a Pelican case for easy transpor...
