The article deals with differences between the conventional mechanical ventilation and a high-frequency ventilation. First,the different physical principles of gas flow are described. Then, effects of the mechanical properties of the respiratorysystem upon intrapulmonary conditions are studied in both ventilatory regimens. Differences between the parameterscharacterising each ventilatory regimen are explained. Finally, the importance of the ventilatory parameters for a safe andefficient application of both conventional and high-frequency ventilations is examined.

Key words:
mechanical ventilation – high frequency ventilation
