N/A patients undergoing mechanical ventilation. Intervention 1: In control group, the headphone was also used to prevent the annoying noises and patients were evaluated twice for one day that the duration of each one was 30 minutes between 9:30-10 AM and 16-16:30 PM. Restrictions imposed were same as intervention group. As the intervention group, all reparatory parameters and other variables were also measured in control group. Intervention 2: In intervention group, instrumental music was played by headphone twice for one day that the duration of each one was 30 minutes between 9:30-10 AM and 16-16:30 PM. The music used in the study was track 1 of Arnd Stein's masterwork, namely Peace in Dream. This track is about 30 minutes. We chose the evening and morning to intervention, because of minimal medical interventions in these times. The researcher was present during the intervention. The respiratory parameters were recorded from the monitor at specified times. And during the study in intervention group, other nonemergency nursing interventions were stopped. The time for recording the respiratory parameters was defined as follows: before using the headphone and playing the music as 0, 10 minutes after playing music as 10, 20 minutes after playing music as 20, 30 minutes after playing music as 30; and all parameters were recorded from monitor of ventilator.
