Anesthesia machines are equipped with ventilators that in many cases are capable of providing life-sustaining mechanical ventilation to patients with respiratory failure. They are used for this purpose every day in the operating room. FDA approved labeling does not provide for using anesthesia ventilators for long term ventilatory support. Nevertheless, anesthesia ventilators are an obvious first-line backup during the COVID-19 pandemic when there are not sufficient ICU ventilators to meet the patient care needs. Local resources and constraints will impact how this solution can best be implemented. Anesthesia machines not currently being used may be located in your own hospital operating rooms, NORA locations, at nearby ambulatory surgery centers, nearby office-based surgery practices, and through your anesthesia equipment distributors. Guidance is available from the manufacturers regarding, but the guidance may not convey all of the clinical considerations. Anesthesia professionals will be needed to put these machines into service and to manage them while in use. Safe and effective use requires an understanding of the capabilities of the machines available, the differences between anesthesia machines and ICU ventilators, and how to set anesthesia machine controls to mimic ICU-type ventilation strategies.
These documents are updated frequently as new information is learned. Let ASA know if you'd like to be notified when the documents are updated.
This document is intended to provide guidance on using anesthesia ventilators safely and effectively as ICU ventilators (PDF Updated May 7, 2020). Detailed information is provided and a quick reference guide (PDF Updated April 9, 2020) is available for downloading. The quick reference guide is intended to be a bedside tool and includes a suggested schedule for monitoring the effectiveness and safety of the anesthesia ventilator.
ASA is working with component societies to develop an inventory of local resources with the goal of moving machines to the locations where they are most needed.
(NOTE: Local conditions will likely dictate modifications to the recommendations provided. This document is intended to provide reference information that empowers caregivers at the bedside to make the best decisions possible to provide safe and effective care.)
