Resumen

CERDA S., Mario. Ventilación de alta frecuencia oscilatoria, un avance en terapia intensiva infantil. Rev. chil. pediatr. [online]. 1999, vol.70, n.3, pp.181-187. ISSN 0370-4106.  http://dx.doi.org/10.4067/S0370-41061999000300002.

Oscilatory high frequency ventilation (OHFV) an advance in pediatric intensive care This article reviews the mechanisms of pulmonary damage caused by conventional mechanical ventilation (CMV) and the recommendations to avoid them. Alternative treatments are reviewed in the management of acute severe respiratory failure in which the patient has failed to respond to CMV. OHFV is recommended as a useful method in the treatment of acute respiratory distress sindrome (ARDS) or severe bronchopneumonia. Critically revising the previous explanations of the mechanisms of gas exhange in OHFV and proposing a new mechanism based on experimental and clinical observations. Concluding that this type of ventilation has demonstrated usefullness in patients with ARDS and severe bronchopneumonia, who do not respond to CMV. At the same time emphasising that only a small number of patients will require OHFV. Finally, reinforcing the idea that the first choice in the management of severe acute respiratory failure is CMV.

Palabras clave : mechanical ventilation; oscilatory high frequency ventilation; gas exchange.
