A filming technique was used for the data collection. The awakenings from sleep were measured using the actigraphy method. The analysis of the data was descriptive, processed using the Statistical Package for the Social Sciences software.Results529 care interventions were identified, grouped into 28 different types, of which 12 (42.8%) caused awakening from sleep for the patients. A mean of 44.1 interventions/patient/day was observed, with 1.8 interventions/patient/hour. The administration of oral medicine and food were the interventions that caused higher frequencies of awakenings in the patients.Conclusionit was identified that the health care interventions can harm the sleep of ICU patients.
