To systematically assess the prevalence of facial pressure injuries related to adult non‐invasive ventilation equipment, and risk factors of facial pressure injuries. PubMed, Cochrane Library, Web of Science, Embase, China Knowledge Resource Integrated Database, Wanfang Database, Chinese Biomedical Database and Weipu Database were comprehensively searched for observational studies investigating the prevalence and risk factors of facial pressure injuries related to adult non‐invasive ventilation equipment from inception to May 16th, 2022. Filter articles based on inclusion and exclusion criteria. The quality of the included studies was evaluated independently by two investigators. Meta‐analysis was conducted using Stata 16.0 software package. In total, 2835 articles were screened and data from 12 studies were used in meta‐analysis. The prevalence of facial pressure injuries related to adult non‐invasive ventilation equipment was 25% (95% confidence interval, CI:15% to 37%, I2 = 97.34%, P < 0.0001). After controlling for confounding variables, the following risk factors of facial pressure injuries: use equipment form, with diabetes, fever, cumulative time of using equipment, facial skin oedema and Glasgow score. Understanding the risk factors of facial pressure injuries can provide the healthcare personnel with the theoretical basis for the management and treatment of the patients.
