| Summary: | <p><strong>Objective </strong> To investigate the effect of respiratory function training on respiratory function and conscious state of patients with severe cerebrovascular disease (SCVD). <strong>Methods</strong> A total of 27 patients with SCVD were divided into control group (N = 17) and observation group (N = 10). Control group received routine drug and rehabilitation treatment, and observation group was added respiratory function training based on routine treatment. The respiratory rate, tidal volume (TV), heart rate, blood pressure and artery oxygen saturation (SaO<sub>2</sub>) of patients were monitored by breathing machine before and after 4-week treatment. Meanwhile, arterial blood gas analysis was used to detect arterial partial pressure of oxygen (PaO<sub>2</sub>), oxygenation index, partial pressure of carbon dioxide (PaCO<sub>2</sub>) and pH value. At the same time, Glasgow Coma Scale (GCS) was used to evaluate the conscious state of patients. <strong>Results </strong> All patients successfully completed 4-week rehabilitation training, without asphyxia, arrhythmia or other adverse events. Compared with before training, the respiratory rate (<em>P</em> = 0.006) and pH value (<em>P</em> = 0.010) were significantly decreased, while SaO<sub>2</sub> (<em>P</em> = 0.001), oxygenation index (<em>P</em> = 0.000) and GCS scores (<em>P</em> = 0.004, 0.017) were significantly increased in both groups of patients after training. There was no statistically significant difference between 2 groups on respiratory function indexes and GCS scores after training (<em>P</em> > 0.05, for all).<strong> Conclusions</strong> Respiratory function training did not significantly improve the respiratory function and conscious state of patients with SCVD, yet to be further studied. Randomized controlled clinical trials with larger, layered samples and long-term prognosis observation are needed. Examination method of respiratory function of SCVD patients is also a topic to be explored.</p><p> </p><p> </p><p><strong>DOI: </strong>10.3969/j.issn.1672-6731.2017.04.007</p>
