Metrological Conformity Assessment of Pulmonary Ventilators During the Covid-19 Pandemic in Brazil

In the health area, service rendering regarding maintenance, calibration, verification, and assays is highly demanded to incorporate new technologies and innovations in procedures and clinical treatment. Physiological life support measures aided by equipment play a fundamental role in the daily life of intensive care units (ICU) during the COVID-19 pandemic. Mechanical ventilation, also known as ventilatory support, is essential for maintaining life; it is a method for treating patients with acute or chronic respiratory problems. Its main objective is to maintain gas exchange. However, it can worsen the patient's clinical condition without adequate calibration. This leads to death. Thus, conducting a metrological assessment of medical and hospital equipment is crucial. The goal of the present study is to perform a metrological study following Technical Standards and Technical Manuals, ABNT NBR IEC 60601–2-12 - 2004 and ABNT NBR ISO 80601–2-12 – 2014, to demonstrate the safety and performance of lung ventilators by evaluating the main ventilatory parameters.
