Clinical significance of mechanical ventilation with respiratory mechanics monitor

Objective To investigate the clinical significance of respiratory mechanics monitor in mechanical ventilation. Methods Patients with invasive mechanical ventilation in our Respiratory Intensive Care Unit (RICU) from January 2014 to December 2015 were enrolled.60 patients were randomly selected as respiratory mechanics group, monitored their respiratory mechanics (include airway resistance, compliance, Pplateau and transpulmonary pressure) to guide the mechanical ventilation parameter adjustment.53 patients were randomly selected as control group and their mechanical ventilation parameter adjusted according to the experience.Their days of mechanical ventilation, RICU length of stay and the incidence of barotraumas were counted. Results Clinical outcomes the respiratory mechanics group compared with control group.Days of mechanical ventilation (6.40±0.82) d vs (5.20±0.63) d (P<0.05) and RICU length of stay (10.49±1.32) d vs (8.83±0.88) d (P<0.05) were shortened.The incidence of barotrauma declined (11.32% vs 3.33%, P<0.01). Conclusions Monitoring of respiratory mechanics in patients with invasive mechanical ventilation can induce days of mechanical ventilation and RICU length of stay, improve the safety of mechanical ventilation.
