INFLUENCE OF HIGH FREQUENCY CHEST WALL OSCILLATION IN HOSPITALIZED PATIENTS WITH COVID-19

Novel coronavirus disease 2019 (COVID-19) infections, declared by the World Health Organization (WHO) as a pandemic, had unprecedented global effects on people's daily activities and way of life. High-frequency chest wall oscillation (HFCWO) have been shown to be effective at loosening and removing airway mucus in hospitalized people. Mucus weight was greater after HFCWO than after traditional airway clearance interventions involving postural drainage and manual percussion and vibration techniques. Earlier diagnosis of COVID-19 may be facilitated by heart rate (HR) and heart rate variability (HRV) monitoring. HR and HRV parameters could not only help to detect COVID-19 in a timely manner but could also help to identify patients at risk for cardiovascular/pulmonary complications. Additionally, HRV and HR parameters may help to assess the course of the disease. The World Health Organization indicates that a resting value of RR \> 30 breaths/min is a critical sign for the diagnosis of severe pneumonia in adults, while the cut-off value for children varies according to age.
