Objectives

Narrative objectives1

High-flow nasal cannula oxygen therapy (HFNCOT) is a noninvasive respiratory management technique for patients with respiratory disorders, including respiratory failure. An example of this is nasal high flow (NHF). Another example is non-invasive positive pressure ventilation (NPPV), which is unintubated continuous supportive ventilation (ventilatory management), although NPPV-treated patients have been shown to be more uncomfortable and anxious than NHF-treated patients (Suzuki Y, et al. J Intensive Care. J Intensive Care. 2014), but no quantitative assessment has been made to date.
This study aims to assess the level of comfort and stress caused by NHF use using multiple assessment methods.

Basic objectives2

Others

Basic objectives -Others

Non-intensive measurement of cerebral blood flow and cerebral oxygen saturation, balance of autonomic nervous system activity, and stress markers in saliva components, which may vary with different respiratory management methods, may contribute to establishing respiratory management methods with higher patient satisfaction. In other words, the use of NHFs may decrease the degree of stress caused by NHF use, as well as increase patient satisfaction and decrease refusal to wear NHFs.

Developmental phase



Assessment

Primary outcomes

Subjective comfort level (VAS) for respiratory management methods

Key secondary outcomes

(i) Salivary stress markers (amylase concentration, salivary cortisol concentration, salivary sIgA concentration, salivary sIgG concentration)
(ii) Blood pressure (systolic, diastolic, average), pulse rate, SpO2, BIS value, sedation score
(iii) Heart rate variability by ECG RR interval
(iv) Tissue oxygenation index, tissue hemoglobin index, oxygenated hemoglobin change, deoxygenated hemoglobin change, total hemoglobin change by NIRS
