Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Dynamic inspiratory muscle strength. Timepoint: Before intervention beginning (pre-operation), 12 hours after patient extubation (post-operation), before patient discharge (post- operation). Method of measurement: The score obtained using an electronic device for measuring respiratory muscle strength and The amount of lung volumes and with using the instructions of the Association of Thoracic Surgeons, which is measured by the stress index (S-index) and the unit of centimeters of water (cmH2O).;Peak inspiratory flow (PIF). Timepoint: Before intervention beginning (pre-operation), 12 hours after patient extubation (post-operation), before patient discharge (post- operation). Method of measurement: The score obtained using an electronic device for measuring respiratory muscle strength and lung volumes and with using the guidelines of the Association of Thoracic Surgeons, for maximum inspiratory airflow in one second and in unit of liters per second.;Patient submaximal functional capacity. Timepoint: Before intervention beginning (pre-operation), before patient discharge from hospital (post- operation). Method of measurement: The distance traveled in meters in the walking test in 6 minutes (6MWT). | — |
Secondary
| Measure | Time frame |
|---|---|
| Quality of life. Timepoint: Before intervention beginning (pre-operation), and two weeks after patient discharge from hospital. Method of measurement: The score obtained using the questionnaire of the quality of life of McNew cardiac patients, which has 27 items.;The level of patient comfort during breathing training. Timepoint: Before intervention beginning (pre-operation), 12 hours after patient extubation (post-operation), and before patient discharge (post-operation). Method of measurement: Using a 5-point scale and visualizing the patients level of comfort while performing breathing trainings, from 1, which is without difficulty , to 5, which is the inability to perform the training.;Hospital length of stay (HLOS). Timepoint: Before the patient is discharged from the hospital. Method of measurement: The number of days the patient was hospitalized, from the day of surgery to the day of discharge from the hospital. | — |
