Experiences of noninvasive ventilation in adults with hypercapnic respiratory failure: a review of evidence

Abstract

Noninvasive ventilation (NIV) has been shown to be beneficial for patients with respiratory failure; however, many patients fail to tolerate it and require other interventions. The objective of this thematic synthesis was to describe the nature of NIV experiences in adults with hypercapnic respiratory failure. A systematic, computerised literature search of English-language databases was undertaken with no restriction on date of publication. A total of 99 papers was identified and screened for eligibility from databases including CINAHL, Medline and PsycINFO, and some were hand searched. 45 papers were critically appraised and 32 met our inclusion criteria. Thematic analysis identified six key themes: benefits of NIV; fear (of various categories, namely, fear of technology/mask, fear of death and dying, and fear of pain and suffering); adaptation to NIV machine; decision making; need for information; and relationship with healthcare professionals. For people using NIV treatment, the experience of being on the NIV machine is unexpected and can be stressful. Findings from this review offer healthcare professionals insights and understanding into the patient experience of NIV. Healthcare professionals may use these findings to implement new strategies in NIV provision and the exploration of the applicability of age-specific supportive care NIV guidelines.
