Aim: The purpose of this case study was to examine the sleep quality of patients\nreceiving noninvasive positive pressure ventilation (NPPV) or nasal\nhigh-flow oxygen therapy (NHF) in an intensive care unit and to investigate\nwhat types of nursing support are offered to such patients. Methods: We\nexamined one patient each for NPPV and NHF. Polysomnography (PSG),\nreview of the patient charts, and semi-structured interviews were used to\ncollect the data for analysis. Results: Patients treated with NPPV or NHF\ndemonstrated a noticeable reduction in deep sleep, with most of their sleep\nbeing shallow. Their sleep patterns varied greatly from those of healthy individuals.\nThese results suggest that, in addition to experiencing extremely\nfragmented sleep, sleep in these patients was more likely to be interrupted by\nnursing interventions, such as during auscultation of breath sounds. Furthermore,\nit was revealed that â??anxiety or discomfort that accompanies the\nmask or air pressureâ? in patients treated with NPPV and â??discomfort that\naccompanies the nasal cannula or NHF circuitâ? in patients treated with NHF\nmay be primary causes of disrupted sleep. Our results suggest a need for\nnursing care aimed at improving sleep quality in patients treated with NPPV\nor NHF.
