Objective To explore the impact of precise quantitative rehabilitation nursing strategies on pulmonary function and prognosis of patients with severe pneumonia undergoing mechanical ventilation in the RICU. Methods Eighty patients with severe pneumonia and mechanical ventilation admitted to the RICU of our hospital from January 2024 to October 2025 were selected as the research subjects and randomly divided into the conventional group and the quantitative group, with 40 cases in each group. According to different nursing plans, the conventional group adopted conventional nursing, while the quantitative group adopted precise quantitative rehabilitation nursing strategies. The lung function, prognosis and incidence of complications of the two groups were compared. Results After the intervention, the lung function of patients in the quantification group improved more significantly, the prognosis-related time was significantly shortened, and the incidence of complications was also reduced, all of which were superior to those in the conventional group. The differences were statistically significant (p<0.05). Conclusion The precise quantitative rehabilitation nursing strategy can effectively improve the pulmonary function of patients with severe pneumonia in the RICU who undergo mechanical ventilation, shorten the prognosis time, and reduce the incidence of adverse conditions. It has clinical promotion and application value.
