Emergency critical illness is a common disease in the emergency department. However, whether it contributes to the effects of pneumatic ventilator on emergency critical remains unknown. Thus, the present study investigated the transport effect of pneumatic ventilator in emergency critical athletic patients using Meta-analysis. A comprehensive literature search was conducted in platforms of PubMed, Embase, Cochrane Library, and Web of Science. The basic features of 5 studies was evaluated using The Cochrane Collaboration's tool for assessing risk of bias. Pneumatic ventilator increased Vt in emergency critical athletic patients (Mean difference = 0.66, 95%CI: 0.38-0.93, p<0.00001). Pneumatic ventilator also increased PEEP in emergency critical patients (Mean difference = 0.29, 95%CI: 0.13-0.45, p=0.0004). Pneumatic ventilator enhanced Ti in emergency critical athletic patients (Mean difference = 0.24, 95%CI: 0.19-0.30, p<0.00001). pneumatic ventilator not affected Ti/Ttot in emergency critical patients (Mean difference = 0.08, 95%CI: -0.18-0.35, p=0.53). Pneumatic ventilator reduced RR in emergency critical athletic patients (Mean difference = -1.65, 95%CI: -2.52--.077, p<0.0002). Pneumatic ventilator increased MAP in emergency critical athletic patients (Mean difference = 5.90, 95%CI: 1.99-9.82, p=0.003). These data demonstrate that The effect of comprehensive nursing for pneumatic ventilator could improve emergency critical athletic patients.
