Introduction:

Anesthesia machines ventilators provide an obvious front-line backup during the COVID-19 pandemic when there are not enough ICU ventilators to meet patient care needs.

Objective:

To update the doctors which are not anesthesiologist, about the differences among the mechanical ventilators and those of anesthesia machine, in order to make them able, to help with the mechanical ventilation of patients suffering COVID-19. Development: The protocols of action of several Societies of Anesthesiology and Reanimation, as well as of Intensive Medicine, of several countries, mainly Spanish, Chilean, and Mexican, were reviewed on the considerations of each one to face in case mechanical ventilation is necessary, with anesthesia machines in patients with COVID-19.

Conclusions:

Modern anesthesia machines and mechanical ventilators have differences; but in this situation, it is a real support so that in places where there are not enough ventilators or they do not reach, the anesthesia machine is the substitute of choice to ventilate patients with COVID-19.
