Ventilación con liberación de presión en las vías respiratorias (APRV): un enfoque para su uso correcto

Abstract

The correct use of APRV provides alveolar opening for most of the respiratory cycle, reducing its movements and pulmonary stress, which reduces the mechanical power and the risk of damage caused by invasive mechanical ventilation. From its beginnings, to the present, ventilation with APRV has been criticized due to the results obtained in several research. Analyzing them, it can be seen that the application of this ventilation mode is not always adequate, interfering with its very objective. In this short-review, we describe the physiological foundations and the correct way to use APRV in intensive care patients, as well as the evidence that justifies the advantages and disadvantages of APVR.
