Abstract

This repository provides English versions of schematic figures illustrating the mechanisms of ventilation failure associated with CO2 absorbent canister replacement during anesthesia. These figures are designed as educational materials for anesthesia providers to better understand anesthesia machine behavior and improve patient safety. The Japanese version of these supplementary figures is available at: https://doi.org/10.5281/zenodo.19420254 --- Version 2.1 Updated the figure of the volume reflector ventilator (Slide 16). Minor revisions were made to improve the visual appearance. --- Version3.0 Updated the figure of the turbine(blower)-type ventilator (Slides 6 & 8) --- Replace the version-specific DOI with the concept DOI for the Japanese version.
