 We encourage users to share concepts they have extracted by writing code which generates a materialized view. These materialized views can then be used by researchers around the world to speed up data extraction. For example, ventilation durations can be acquired by creating the ventdurations view in [etc/ventilation-durations.sql](https://github.com/MIT-LCP/mimic-code/blob/master/concepts/ventilation-durations.sql).
