- Abstract:
- Abstract: Objective To explore the effects of a new intelligent ventilation mode on clinical respiratory mechanics in patients with acute respiratory distress syndrome (ARDS). Methods A total of 84 patients with ARDS were divided into observation group (42 cases) and control group (42 cases) according to the simple random number table method. New intelligent ventilation mode (intelligent trigger + adaptive minute ventilation) was adopted in observation group, and conventional ventilation mode (synchronous intermittent command + pressure support ventilation) in control group. The mechanical ventilation-related indexes, respiratory mechanics indexes and blood gas indexes were compared between two groups. Results The ventilation time, manual operation frequency, ventilator alarm frequency and mechanical energy in observation group were less than those in control group (P<0.05). After ventilation, the respiratory rate, minute ventilation and static lung compliance of two groups of patients were increased and there were drops in peak airway and airway closure pressure (P<0.05). The respiratory frequency and static lung compliance of observation group after ventilation were significantly higher than those of control group (P<0.05), but there was no statistically significant difference between two groups in minute ventilation, airway peak and airway closure pressure (P>0.05). The pH of two groups of patients after ventilation was close to that before ventilation (P>0.05). After ventilation, PaO2 of two groups of patients was higher than that before ventilation, and PaCO2 was lower (P<0.05) and the differences between two groups in pH and PaO2 after ventilation were trivial (P>0.05) and the PaCO2 of observation group after ventilation was significantly lower than that of control group (P<0.05). Conclusion The new intelligent ventilation mode used in the treatment of ARDS can shorten ventilation time, reduce mechanical energy and lessen the workload of medical care. Moreover, it can effectively improve the blood gas index and respiratory mechanics index of patients, and protect the lung function.
