It is expected that the association of photobiostimulation techniques with low lightpower; using LEDs in the red-infrared light band and conventional treatment of respiratory physiotherapy are effective in improving lung function; ventilatory mechanics and inspiratory and expiratory muscle strength for the treatment of patients with sars-cov-2; in addition to optimizing the clinical condition of the patient with repercussions on respiratory rate and pulse oximetry.
