Objective To analyze the effect of non-invasive ventilator on patients with chronic obstructive pulmonary disease -COPD) complicated with severe respiratory failure. Methods the data of 40 COPD patients with severe respiratory failure who did not receive non-invasive mechanical ventilation from March 2020 to March 2020 were collected and 2021, the data of 40 COPD patients with severe respiratory failure who received non-invasive mechanical ventilation from April 2022 to April 2022 were 2023, the vital signs, lung function and blood gas analysis were compared between the two groups. Results before treatment, there was no significant difference between the two groups (P > 0.05), but after treatment, the observation group was better than the control group (p < 0.05). Conclusion non-invasive mechanical ventilation is effective in the treatment of COPD patients with severe respiratory failure, which can stabilize the vital signs, increase the Oxygenation, correct hypoxia and improve respiratory failure.
