Objective:To analyze the advantages of the pressure-regulated volume control (PRVC) mode compared with the traditional continuous mandatory ventilation (CMV) mode about mechanical ventilation efficiency of ventilator.Methods: For the mechanical ventilation situations, the parameters of PRVC mode, V-CMV mode and P-CMV mode under same detecting conditions were tested by using gas analyzer, which based on the ventilation principle of PRVC mode. And then the differences between PRVC mode and CMV modes were analyzed. Results: PRVC mode can supply the almost same tidal volume, and provide lower pressure and higher compliance compare with the V–CMV mode under the same conditions. On the other hand, PRVC mode can supply more tidal volume and slightly higher compliance compare with the P–CMV mode under the same pressure.Conclusion: PRVC mode has combined with the advantages of CMV mode, and it can make sure the target tidal volume, at the same time, reduce the pressure of airway, and improve the compliance for circuit. It also can make the mechanical ventilation to got more efficiency and more safety.
