Abstract
Aim: The purpose of this case study was to examine the sleep quality of patients receiving noninvasive positive pressure ventilation (NPPV) or nasal high-flow oxygen therapy (NHF) in an intensive care unit and to investigate what types of nursing support are offered to such patients. Methods: We examined one patient each for NPPV and NHF. Polysomnography (PSG), review of the patient charts, and semi-structured interviews were used to collect the data for analysis. Results: Patients treated with NPPV or NHF demonstrated a noticeable reduction in deep sleep, with most of their sleep being shallow. Their sleep patterns varied greatly from those of healthy individuals. These results suggest that, in addition to experiencing extremely fragmented sleep, sleep in these patients was more likely to be interrupted by nursing interventions, such as during auscultation of breath sounds. Furthermore, it was revealed that “anxiety or discomfort that accompanies the mask or air pressure” in patients treated with NPPV and “discomfort that accompanies the nasal cannula or NHF circuit” in patients treated with NHF may be primary causes of disrupted sleep. Our results suggest a need for nursing care aimed at improving sleep quality in patients treated with NPPV or NHF.

Summary
The quality of sleep is impaired in critically ill patients [1] [2]. Sleep disorders are likely to be affected by endocrine function modulation [1], impaired immunity, cognitive function, pain [2], as well as discomfort [3] [4]. This is an issue that cannot be ignored by intensive care unit (ICU) medical teams providing support to critically ill patients. It has been found that both environmental and physiological/psychological factors contribute to the development of sleep disorders in the ICU [5]. It is true that numerous critically ill patients complain of lack of sleep
