Evaluation of an automatized AMBU ESSI-1 INC designed at the Instituto Nacional de Cardiología Ignacio Chávez.

Objective: The objectives of this study were to evaluate an automated device for ventilatory support based on AMBU manufactured in March 2020.

Methods: The ESSI-1 INC was evaluated through pulmonary mechanics and physiology parameters through compensatory spirometer tests (TISSOTs), and an artificial lung Model5600i Dual Adult PNEU VIEW SYSTEM; it was also compared to the anesthetic ventilatory support equipment (AEONMED 7500) in porcine models, measuring ventilatory, hemodynamic and gasometric parameters.

Results: This equipment (ESSI-1 INC) was successfully tested by mechanical and biological models, such as pigs in which its performance was evaluated in terms of variability of tidal volume, ventilation frequency, and I/E relationship versus the manual performance of two medical interns.

[Recommendations for airway management in a suspected or confirmed case with COVID-19. A protocol of the Department of Cardiovascular Anesthesia of the National Institute of Cardiology Ignacio Chávez].

The new coronavirus SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2), detected in Wuhan, China, causes coronavirus disease 2019 (COVID-19), which was declared pandemic, and has caused more than 19 million confirmed cases and more than 700 thousand deaths worldwide. When our institution was converted to COVID’s hospital since early April 2020, specific care protocols were developed, with the aim of improving the quality of care and safety of patients and the staff involved in their management. Airway management represents one of the highest risks of direct contact infection with aerosol generation (orotracheal intubation, secretion aspiration, extubation, cardiopulmonary resuscitation, high flow oxygen therapy, noninvasive ventilation, and invasive ventilation).
