At the same time as the intervention group, hemodynamic indices and restlessness were recorded immediately and 10 minutes later during the study.

Hemodynamic parameters include heart rate, respiratory rate, systolic and diastolic blood pressures, mean blood pressure, pulse pressure, arterial oxygen saturation, and Richmond Agitation-Sedation Scale Questionnaire for measuring restlessness and using Glasgow criteria for measuring the level of consciousness of the samples Before and immediately and 10 minutes after intervention.
