Vital signs
INTERACTION
There were also significant interactions between groups and time (pretest–posttest) on SBP, HR, and RR (with all Interaction The simple effect of groups indicated that the experimental group showed reduced SBP at 1st post-test (t = 3.300, Inter group comparison of vital signs (SBP, DBP, HR, and RR) at different measure times (mean). Measurements were made at 4 time points: baseline, before music therapy after extubation; Time 1, after music therapy after extubation; Time 2, after music therapy on the second day after transfer to the general ward; and Time 3, after music therapy on the day of 1 day before discharge. (*The simple effects of time indicated a statistically significant decreased SBP in the experimental group (F = 26.10,
