Overview

Brief Summary

The COVID-19 pandemic, a disease caused by the SARS-CoV-2 virus, has generated an inexplicable scenario for global health, causing different complications and degrees of functional impairment in millions of people who manage to recover from the disease. The respiratory system is the main system to be directly impacted during COVID-19 infection, and its treatment can generate changes in the respiratory function of individuals surviving the exacerbation of the disease, which may promote subjective and quantitative changes in the respiratory pattern, requiring an evaluation with high-cost instruments, an evaluation necessary to outline a better planning therapeutic for this population. The goal of this study is evaluate the breathing pattern variables using a device called RESPIRATORY DIAGNOSTIC ASSISTANT (RDA) and verify the relationship between the breathing pattern variables with the variables of pulmonary function, respiratory muscle strength and respiration in patients after involvement by COVID-19. This is a observational and validation study, prospective with follow-up of respiratory function for 6 months, a subproject linked to the project already approved by the research ethics committee under opinion: 4.362.977/4.596.02. Data collection will be carried out in a single day and divided into a few steps that will take place at the cardiopulmonary physiotherapy laboratory located at the physiotherapy department of the Federal University of Pernambuco. The first step is to conduct an interview with the participants to collect clinical data and perform a physical examination. Subsequently, a multidimensional evaluation of respiratory function will be performed. Statistical analysis will be performed using the Statistical Package For Social Science (SPSS) software version 20.0 for Windows. The Kolmogorov-Smirnov test will be used to verify the type of distribution, regarding the normality of the variables, and the significance level adopted will be 95% (α <0.05) for all analyses. Finally, the data obtained will be presented in tables and/or graphs.

Detailed Description

The sample will consist of volunteers with laboratory confirmed COVID-19 results who have SARS COV 2 variants tracked by the epidemiological surveillance of Caruaru-Pernambuco and will be recruited by coexistence in a non-probabilistic way. The sample study will be obtained through data provided by the municipal health department of the city of Caruaru-Pernambuco with a predicted sample of 131 people. In order to minimize sample losses, 10% will be added to the total sample, which corresponds to 144 participants. The software that can be used is known as GPower (version 3.13 for Windows) considering a statistical power (β) of 80% and a significance level (α) of 5%.

Outcomes

Primary Outcomes

Breathing pattern variables

Time Frame: "Until the Completion of the Study, On Average 1 Year"

The algorithm of the "Respiratory Diagnostic Assistant" device relates the variables respiratory rate, tidal volume, minute volume, inspiratory flow, expiratory flow, relationship between inspiratory and expiratory times. The variables of the breathing pattern will also be quantitatively evaluated:: * Respiratory rate in incursion per minute * Tidal volume (measured in liters) * Minute volume (measured in liters); * Inspiratory flow (measured in liters); * Expiratory flow (measured in liters); * Ti/Ttotal, (measured in segunds) * I:E , relationship between inspiratory and expiratory times * Volume vs time; * Flow vs time.

Breathing pattern diagnosis

Time Frame: "Until the Completion of the Study, On Average 1 Year"

The algorithm of the "Respiratory Diagnostic Assistant" device relates the variables respiratory rate, tidal volume, minute volume, inspiratory flow, expiratory flow, relationship between inspiratory and expiratory times, providing classification of breathing pattern during rest breathing. The "Respiratory Diagnosis Assistant" algorithm provides through graphs allowing the classification of the diagnosis in normal or altered. * Normal breathing pattern described in frequency of cases. It is defined no changes by the algorithm of the "Respiratory Diagnostic Assistant". * Altered breathing pattern described in frequency of cases. It is defined by changing the breathing pattern variables captured by the flow sensor of the "Respiratory Diagnostic Assistant" device during breathing at rest.

Secondary Outcomes

  • Assessment of lung volumes and capacities by ventilometry("Until the Completion of the Study, On Average 1 Year")
  • Maximum inspiratory pressure (Manuvacuometry)("Until the Completion of the Study, On Average 1 Year")
  • Lung Function("Until the Completion of the Study, On Average 1 Year")
  • Maximum expiratory pressure (Manuvacuometry)("Until the Completion of the Study, On Average 1 Year")
