Summary
| Description |
English: An animated diagram illustrating a simplified schematic of a closed-system ventilator (a.k.a respirator) where a CO2 filter recycles air to reduce waste and an outflow valve controlled by the ventilator releases pressure that builds up as more and more fresh air is added to the closed system. The fresh gas flow is an optimized mix so they can control the oxygen ratio, eliminate particulates, etc. This type usually used in our anesthesia ventilator because the anesthesia gas is expensive, so all the gases (air, oxygen, anesthesia gas, etc.) are kept constrained in the tubing and re-breathed. |

This illustration is a collaboration Eleanor Lutz and Sarah Low to explain ventilators in a series of animations; including also file:Open circuit ventilator.gif and file:Biology of ventilation.gif.
At the time of their collaboration, Sarah was an anesthesiology resident at Massachusetts General Hospital, and a leader of CoVent-19 - one of many efforts to address the ventilator shortage during the Covid-19 outbreak, and Eleanor Lutz is an information designer specializing in science communication who worked at the New York Times in the graphics department, as part of the year's fellowship cohort, who before researched disease mosquitoes for my PhD in biology and data science.
