Primary Outcome Measures

Name	Time	Method
The pulmonary volumes and capacities. Timepoint: The Measurement of pulmonary volumes and capacities at the beginning of the study and 15, 30, 60 and 90 minutes after the beginning of the intervention. Method of measurement: Perform the spirometry test in two consecutive days.;The respiratory indicators. Timepoint: At the beginning of the study and 15, 30, 60 and 90 minutes after the beginning of the intervention. Method of measurement: The Respiratory Rate by counting the number of chest ups and downs and the percentage of oxygen saturation of the blood using the pulseoximetry device.
