all the patients admitted to the icus during the study period will be screened. we will not set any restrictions regarding the timing of the prescription of cpt (i.e., length of icu stay before screening) for the screening. we will include only if cpt is expected to be used as management at least for the next 24 hours in the icus from the time of inclusion. for instance, if cpt will be expected to be discontinued from the management in a day, we will exclude them from the inclusion. cpt can be prescribed for airway clearance with any etiology such as atelectasis at the directions of bedside intensivists in charge of the study date. specific inclusion criteria * patients diagnosed as covid-19 * patents strongly suspected its infection and the result of virological testing is pending as of screening. * patients with any type of mechanical ventilation (i.e., invasive, non-invasive, high flow nasal therapy) * patients are on standard oxygen by mask or nasal cannula and the fio2 provided can be measurable. * patients who are on respiratory monitoring at least spo2 can be continuously measurable.
