Indices of Borg dyspnea and perceived CRM in persistent COVID-19 patients with pulmonary hypertension

ABSTRACT

The SARS-CoV-2 that causes the COVID-19 disease, clinically ranges from mild flu-like episodes to other serious and even life-threatening, especially due to acute respiratory failure, regardless of the severity the acute course can be overcome, however, the persistence of symptoms or multi-organ symptom complex, called persistent COVID. Among these persistent symptoms is respiratory distress. A descriptive, observational and cross-sectional study was carried out in 29 people diagnosed with persistent COVID-19 plus comorbidity pulmonary hypertension, between 2019 and 2021. The Borg dyspnea scales were applied at rest and by stress test Walk test in 6;and the Medical Research Council dyspnea scale. IFB B categorizes between 0 and 2 and high R2 (0.7993) explains the perception of respiratory discomfort that appears with activity levels that do not normally cause this type of discomfort (daily activity), and can be weighted by the level of activity necessary for it to be triggered. Both scales have validity, reliability, specificity, sensitivity and predictive value for the use that has been established, easy to use and understand.
