Mechanical ventilator test protocol for care of patients with covid-19 in porcine model

Abstract

As a result of the SARS-CoV-2 pandemic, health systems globally have seen a dramatic increase in the occupancy of intensive care units, with mechanical ventilators being a resource in high demand in the care of these patients. This article proposes a protocol for testing low-cost mechanical ventilators in pig models, as part of the development of locally manufactured biomedical equipment that can support the health crisis caused by the pandemic. The protocol addresses aspects that include the pre-test phase, anesthetic and airway management, laboratory monitoring, recovery and monitoring of the animal. This document presents to the academic community a validation protocol of a mechanical ventilator prototype in a pig specimen that can be a reference for its application and revalidation by other groups interested in the development of local and low-cost technologies.
