SECONDARY outcome

Timeframe: 10 days during inhalation

The concentration of SpO2 by Pulse oximetry device during procedures in the groups. The measure was done before and after each inhalation (total 4 measures per day). The intraday SpO2 data of all patients in groups was calculated as Median with Inter-Quartile Range and presented in the table by days.
