Simple vs Complex Ventilator Function

Basics

• Needs better name?
• Heavily paraphrased + early writing, double check everything, wait for more info to be added etc
• Simple bag squeezing mechanisms are only usable under heavy sedation due to the fact breathing is sort of forced, and thus if the person tries to breathe, they are not "in sync"
  • Word for this is "forced breath"
  • Barotrauma can occur when the diaphram pushes simutaniously with the air pump pushing
• may work as a sort of immediate help, but main issue is the long term care causing backlog?

• A Video by "Real Engineering" on this
• BVM (bag valve mask) is the bag method
• Barotrauma due to long term/improper mechanical ventilation https://en.wikipedia.org/wiki/Barotrauma#Ventilator-induced_barotrauma

Problems that occur with mechanical ventilation

• Deeply sedated BMV works for immediate to ~ 1 day with heavy sedation

What is Done to Fix These Issues

• Positive End Experitory Pressure "Peep"
• Varying pressure + flow
• Predicting/Measuring in real time when the patient is attempting to breathe, and syncing the pump to that
• Mit 2010 BVM Design, with sensors to make it more measurable still not perfect
• Lots of easily usable io + lots of degrees/infinite variability
• Pressure, Volume, Oxygen Percentage are main variables, is humidity?
• Agva Healthcare Device liscencing design, open source?

Info that Needs Research

• Refresh rate of arduino / rasp pi for sensors
• Sensors needed + wherein the "flow" of the machine
• Air + o2 source (external/internal?)
