BackgroundNot only arterial hypoxemia but acute lung injury also has become the major concerns of one-lung ventilation (OLV). The use of pressure-controlled ventilation (PCV) for OLV offers the potential advantages of lower airway pressure and intrapulmonary shunt, which result in a reduced risk of barotrauma and improved oxygenation, respectively.MethodsWe searched Medline, Embase, the Cochrane central register of controlled trials and KoreaMedto find publications comparing the effects of PCV with those of volume-controlled ventilation (VCV) during intraoperative OLV in adults. A meta-analysis of randomized controlled trials was performed using the Cochrane Review Methods.ResultsSix studies (259 participants) were included. The PaO2/FiO2 ratio in PCV was higher than in VCV [weighted mean difference (WMD) = 11.04 mmHg, 95 % confidence interval (CI) = 0.30 to 21.77, P = 0.04, I2 = 3 %] and peak inspiratory pressure was significantly lower in PCV (WMD = −4.91 cm H2O, 95 % CI = −7.30 to –2.53, P < 0.0001, I 2 = 91 %). No differences in PaCO2, tidal volume, heart rate and blood pressure were observed. There were also no differences incompliance, plateau and mean airway pressure.ConclusionsOur meta-analysis provided the evidence of improved oxygenation in PCV. However, it is difficult to draw any definitive conclusions due to the fact that the duration of ventilation in the studies reviewed was insufficient to reveal clinically relevant benefits or disadvantages of PCV. Significantly lower peak inspiratory pressure is the advantage of PCV.Electronic supplementary materialThe online version of this article (doi:10.1186/s12871-016-0238-6) contains supplementary material, which is available to authorized users.

“…Firstly, sternotomy has been questioned as a risk factor for post-operative lung dysfunction as thorax opening is known to cause an increase in both pulmonary compliance and volume, potentially enhancing shear and tear lesions. [7][8][9] Secondly, Petak found that pulmonary compliance reversibly decreased in isolated rat lungs as a consequence of pulmonary hypoperfusion. 10 Guastavino 11 found that compliance decreased immediately in dogs when CPB started and partially increased when it stopped, thus, CPB was able to induce an immediate drop in pulmonary compliance.…”

“…At present, there are a variety of mechanical ventilations controlled models, such as Pressure Controlled Ventilation (PCV) and Volume Controlled Ventilation (VCV) ‎[ 3 ]. On the base of PCV, the models of Pressure Support Ventilation (PSV), Pressure Released Ventilation (PRV), Pressure Regulated Volume Ventilation (PRVC) and Bi-Level Positive Airway Pressure (BIPAP) Controlled Ventilation are developed [ 4 – 10 ]. Among them, as a similar universal breathing model ‎[ 11 ], BIPAP gets a wide range of application due to the characteristics of pressure control, well man-machine coordination [ 12 – 17 ].…”

In recent studies on the dynamic characteristics of ventilation system, it was considered that human had only one lung, and the coupling effect of double lungs on the air flow can not be illustrated, which has been in regard to be vital to life support of patients. In this article, to illustrate coupling effect of double lungs on flow dynamics of mechanical ventilation system, a mathematical model of a mechanical ventilation system, which consists of double lungs and a bi-level positive airway pressure (BIPAP) controlled ventilator, was proposed. To verify the mathematical model, a prototype of BIPAP system with a double-lung simulators and a BIPAP ventilator was set up for experimental study. Lastly, the study on the influences of key parameters of BIPAP system on dynamic characteristics was carried out. The study can be referred to in the development of research on BIPAP ventilation treatment and real respiratory diagnostics.
