Avoid ventilators like the plague (or the coronavirus)
The air we breathe consists of 21% oxygen - this is what humans have
evolved to breathe in naturally. Ventilators pump pure 100% oxygen
directly into the lungs which, for an average human, after 16 hours will
put their life at serious risk of death. For the elderly and at-risk
patients, this will happen a lot sooner. This is why the survival rate
for ventilators is so low. You stand a better chance of suviving the
flu, sorry, covid, if you just wait it out.
