Abstract: Objective To explore the effect of non-invasive ventilator-assisted respiration on the prognosis of patients with acute cerebral hemorrhage and respiratory failure type II. Methods A total of 90 patients with acute intracerebral hemorrhage and respiratory failure type II admitted to Hotan District People's Hospital from February 2020 to January 2023 were selected, and the patients were divided into observation group and control group, with 45 patients in each group. The control group was treated with invasive ventilators on the basis of routine treatment, and the observation group was treated with non-invasive ventilators on the basis of routine treatment. The clinical treatment effect and respiratory function index changes of the two groups were compared, and the ICU hospitalization time, ventilation time, total hospitalization time, tracheotomy rate, hospital mortality rate and hospital infection rate of the two groups were compared. Results There was no significant difference in the total clinical effective rate between the two groups (P>0.05). PaO₂ levels and PaCO₂ levels increased after 12 h and 24 h after treatment, but there was no significant difference between PaCO₂ and PaO₂ levels before, 12 h and 24 h after treatment (P>0.05). There was no significant difference in the tracheotomy rate and mortality rate between the two groups (P>0.05). The length of stay, ventilation time, total length of stay and infection rate of patients in the observation group were significantly lower than those in the control group (P<0.05). Conclusion Both non-invasive and invasive ventilator-assisted breathing can improve the treatment effect of respiratory failure and improve the respiratory function index of patients with acute cerebral hemorrhage complicated with respiratory failure type II, but non-invasive ventilator-assisted breathing can improve the prognosis of patients, reduce the time of hospitalization and ventilation, and reduce the incidence of nosocomial infection.
