Avaliação técnico-econômica da ampliação na rede de gases em hospital de referência para tratamento de COVID-19

Abstract

Oxygen since its discovery is seen as an essential gas for human life. In 2019, with the worldwide evolution of COVID-19/SARS-COV-2, capable of obstructing the pulmonary arteries hindering breathing and causing diseases similar to pneumonia, it required intensification of demands for health support. In particular, medicinal gases, such as oxygen, demanded in large quantities and with high purity for health and hospital systems and intensive care units to combat COVID-19 and its clinical evolution in patients. The work consists of the design of a network expansion for oxygen gases, medicinal air and clinical vacuum for an intensive care hospital unit of a reference hospital. An 12-bed intensive care unit was designed with a gas network to assist patients in intensive care. The project, faithful to current Brazilian standards, presents the dimensioning of beds, consumption, sources of supplies, equipment sizing and cost and investment analysis. In the first stage, the consumption of gases, the material necessary for construction and equipment, such as clinical vacuum pump and medical air compressor, were evaluated. After this first stage, the gas network was dimensioned considering and the demand of the reference hospital. The conclusion of this work presents a brief economic analysis for investment in the construction of these 12 ICU beds for a reference hospital, considering that presented economic viability in the realistic and optimistic scenarios, which was not obtained in the pessimistic.
