Study & Design

Study Type: interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Respiratory status of patients after coronary artery bypass graft surgery. Timepoint: The second, third, fourth day after surgery. Method of measurement: The arterial blood oxygen saturation of the pulse oximetry device and the intensity of pain are assessed with a 10-point VAS visual criterion.

Secondary Outcome Measures

Name	Time	Method
Respiratory status. Timepoint: Periods of respiratory status assessment as a consequence can be stated at the beginning of the study (before the intervention) and the first, second and third days after the start of respiratory training. Method of measurement: Hearing the lungs of patients.;Oxygen saturation rate. Timepoint: Arterial blood oxygen saturation on the second, third and fourth day after the start of breathing exercises. Method of measurement: Pulse oximetry.;VAS standard score. Timepoint: VAS standard score after the end of the respiratory training course. Method of measurement: VAS criteria.
