Recruitment manoeuvres on high frequency oscillation ventilation

High frequency oscillation versus conventional ventilation: is one superior?

Ventilatory management of ARDS: high frequency oscillation and lung recruitment!

Many aspects of ventilatory management in patients with ARDS are still controversial and one of the major controversies is should HFO or CMV ideally be used to manage this patients. As shown by David et al. when the two approaches to ventilatory support are applied using similar principles the physiologic outcomes appear to be similar. With both approaches the use of lung recruitment maneuvers ...

Open the lung with high-frequency oscillation ventilation or conventional mechanical ventilation? It may not matter!

The 'open lung' approach has been proposed as a reasonable ventilation strategy to mitigate ventilator-induced lung injury (VILI) and possibly reduce acute respiratory distress syndrome (ARDS)-related mortality. However, several randomized clinical trials have failed to show any significant clinical benefit of a ventilation strategy applying higher positive end-expiratory pressure (PEEP) and lo...

High-frequency oscillation ventilation for hypercapnic failure of conventional ventilation in pulmonary acute respiratory distress syndrome

INTRODUCTION High-frequency oscillation ventilation (HFOV) is regarded as particularly lung protective. Recently, HFOV has been shown to be not beneficial for acute respiratory distress syndrome (ARDS) patients in general. Due to its special physical effects, it could be beneficial, however, in inhomogeneous ARDS. This study evaluates the effect of HFOV on PaCO2 removal in hypercapnic patients ...

No effect of oral high frequency oscillation combined with forced expiration manoeuvres on tracheobronchial clearance in chronic bronchitis.

This study compared the effect of oral high frequency oscillation (OHFO) with the effect of the forced expiration technique (FET) on tracheobronchial clearance. Eight patients with chronic bronchitis were investigated (mean age 60 +/- 10 yrs, mean forced expiratory volume in one second (FEV1) 68 +/- 27% predicted, mean sputum production 33 +/- 9 g.day-1). OHFO was applied at the respiratory sys...
