Accordingly, a list of participants’ names was created and their names were numbered from one to sixty. Then, a random allocation software was used to randomly allocate numbers 1–60 to two groups. The fourth author independently generated allocation sequence and concealed it so that participants, statistical analyst, and the second and the third authors were blind to the sequence. For this purpose, we make our list of Participants and assign each participant a number. Again, we used a random number generator to place each participant in one of the two groups. The following steps were taken to select samples: 1. Preparing a list of all the Participants were enrolled from the databases of these hospitals; 2. A list of all Participants was prepared initially, and then each member was marked with a specific number (Assigned a sequential number to each Participants (1,2,3…60)). 3. Sample size was calculated at 32 according to the following criteria: (Ζ1- α/2 =1.96, α= 0.05, β= 0.1, σ= 6 and d= 5). 4. The samples were randomly selected by the random number generator software (the participants generated randomly without human interference). However, 30 Participants were recruited to each group (30 Participants ) to increase the study power. The fourth author independently generated the allocation sequence and concealed it, so that the participants, the statistical analysts, and the third author were blind to the sequence. N/A Comparison of the effect of chest compression during exhalation with physical therapy using vibration and percussion methods on isolation indices in patients under mechanical ventilation.. Intervention 1: Intervention group: Compression of the chest during exhalation. Intervention 2: Physiotherapy group using vibration and precision method.
