Restrictive respiratory pathologies (RRP) such as pulmonary fibrosis, interstitial lung disease, and systemic sclerosis are characterized by a decrease in the lungs' ability to expand and contract adequately. This leads to dyspnea, hypoxemia, and reduced quality of life. In severe cases, mechanical ventilatory support may be required. The main objective of the present study is to evaluate the available evidence on the use of high-flow oxygen (HFO) in patients with RRP. We seek to analyze in detail the physiological effects of HFO in this context, the potential clinical benefits, the safety considerations associated with its use and the areas that require further investigation. The design of the study was descriptive, cross-sectional, retrospective literature review type. HFO has emerged as a promising alternative to conventional mechanical ventilation. Studies show that HFO improves oxygenation, decreases the work of breathing, and increases lung capacity in patients with RRP. Clinically, reduction in dyspnea, less need for intubation and reduction in mortality have been observed. HFO emerges as a promising therapeutic option, with applications in the management of acute decompensations and pulmonary rehabilitation programs. However, more research is needed to define its optimal role in the treatment of restrictive respiratory pathologies.
