Efeitos adversos agudos e conforto da interface máscara de mergulho como estratégia de suporte ventilatório durante a ventilação não invasiva

Abstract

Objective: to evaluate the acute adverse effects and comfort of the diving mask interface as a ventilatory support strategy during non-invasive ventilation. Methodology: Clinical, experimental and descriptive study, carried out in the laboratory of the Clinical Research Unit, of the Federal University of Ceará, in the period of June and July 2020. Twelve healthy volunteers were studied. A single-limb circuit noninvasive ventilatory support model was used, coupled with a diving mask, compressed air cylinder (flow of 15L/min) and PEEP valve (5cmH2O), during the period of 60 minutes. The variables evaluated were: physiological parameters (heart rate, respiratory rate, blood pressure and peripheral oxygen saturation), venous blood gases, visual analog scale and adverse effects related to the interface. Results: The sample consisted of 12 women with an average age of 25.58 ± 3.47. There was no statistically significant difference between the gasometric data when comparing the values before and after using the interface. The level of respiratory distress was scored as mild during the use of the interface. The adverse effects with the greatest degree of problem were: mask pressure, chest discomfort, mask weight and pressure in the ear. Conclusion: The diving mask interface seems to be feasible, with no serious levels of adverse effects that would make its use unfeasible, however, to expand its clinical applicability, improvements are necessary.
