Background: Noninvasive ventilation (NIV) is a modality that supports patient breathing through different types of face ‏interfaces, such as a full-face mask and nasal mask. Noninvasive Ventilation modalities have proven to improve morbidity and mortality rates for patients suffering from respiratory failure in the hospital setting and Outpatient. It also helped prevent escalating the treatment to more advanced methods such as invasive ventilation. However, several elements are required for optimizing the therapy, including Health care providers' training in operating the different brands of NIV, equipment availability, cost, and appropriate adjustment to the settings according to patient response. Purpose: This study aims to assess the level of perception of maximizing patient comfort during non-invasive ventilation devices among respiratory therapists at KFSH&RC by utilizing specific features of NIV. For instance, ramp, Flex, humidification, and auto-adjusting pressure. In addition, how RTs perceive mask selection and other contributing factors that contribute to maximizing patients' comfort. Methods: The study used an online, cross-sectional survey with 20 questions were sent to Respiratory therapists at KFSH&RC. In this survey, data collected from targeted population regarding their perceptions of skills for maximizing patient comfort during non-invasive ventilation will be analyzed using the Statistical Package for the Social Sciences (SPSS). Result: The findings indicated that respiratory therapists at KFSH&RC generally hold a positive view about utilizing various aspects of NIV, such as auto-adjusting pressure, noise reduction, humidification, and specific NIV settings, to maximize patient comfort. They also recognized the importance of effective communication, patient encouragement, and addressing patient comfort before and after initiating NIV therapy. The study found that demographic factors like gender, country of graduation, years of experience, and age did not significantly impact the therapists' attitudes, except for therapists working in respiratory care community services (RCCS), who placed greater emphasis on maximizing patient comfort during NIV (P=.019). Conclusion: This research conducted at King Faisal Specialist Hospital & Research Centre (KFSH&RC) concluded that respiratory therapists demonstrated positive perception about utilizing different elements of NIV to maximize patient comfort during therapy. Majority of therapists believed that features such as auto-adjusting pressure, noise reduction, humidification, and the utilization of certain NIV settings such as the FLEX and RAMP have significance for enhancing patient comfort.
