COMBINED HIGH FREQUENCY AND CONVENTIONAL VENTILATION

Superimposed high frequency ventilation with conventional mechanical ventilation.

A 73-year-old man with ARDS-multiple organ failure due to Chlamydia psittaci, was successively supported with conventional respiratory techniques. After 48 hours of no clinical improvement, HFV was superimposed to CMV in order to combine the advantages of each one. Since improvement has been seen in all ventilatory parameters, this method is suggested as another mode of ventilation for patients...

Advanced Monitoring System for Conventional and High Frequency Ventilation

Th ere are many techniques of conventional artifi cial lung ventilation (CV) that are widely used in clinical practice. However, these techniques can cause severe lung damages and also circulatory problems. Searching for new methods of artifi cial lung ventilation (ALV) that can provide the necessary gas exchange in lungs leads to implementation of new unconventional ventilatory techniques, esp...

High frequency oscillation versus conventional ventilation: is one superior?

Comparison between conventional protective mechanical ventilation and high-frequency oscillatory ventilation associated with the prone position

OBJECTIVE To compare the effects of high-frequency oscillatory ventilation and conventional protective mechanical ventilation associated with the prone position on oxygenation, histology and pulmonary oxidative damage in an experimental model of acute lung injury. METHODS Forty-five rabbits with tracheostomy and vascular access were underwent mechanical ventilation. Acute lung injury was indu...

High‐frequency oscillatory ventilation versus conventional ventilation: hemodynamic effects on lung and heart

Abstract High-frequency oscillatory ventilation (HFOV) may improve gas exchange in patients who are inadequately ventilated by conventional mechanical ventilation (CV); however, the hemodynamic consequences of switching to HFOV remain unclear. We compared the effects of CV and HFOV on pulmonary vascular conductance and left ventricular (LV) preload and performance at different airway and fillin...
