high frequency oscillatory ventilation in severe respiratory failure

Prospective, randomized comparison of high-frequency oscillatory ventilation and conventional mechanical ventilation in pediatric respiratory failure.

OBJECTIVE To compare the effectiveness of high-frequency oscillatory ventilation with conventional mechanical ventilation in pediatric patients with respiratory failure. SETTING Five tertiary care pediatric intensive care units. DESIGN A prospective, randomized, clinical study with crossover. PATIENTS Seventy patients with either diffuse alveolar disease and/or airleak syndrome were rando...

Respiratory input impedance during high frequency oscillatory ventilation.

Total respiratory input impedance (Zrs) measured by forced excitation may be computed easily from pressure and flow measurements recorded at the airway opening. The purpose of this paper was to analyse how the information provided by Zrs may be used for monitoring ventilatory mechanics during high frequency oscillatory ventilation (HFOV). We measured impedance (0.125-32 Hz) in six dogs, and in ...

High-frequency oscillatory ventilation for acute respiratory distress syndrome.

OBJECTIVE To evaluate the effectiveness of HFOV in pediatric patients with acute respiratory distress syndrome. METHODS In this retrospective study, we reviewed all 20 pediatric patients, who were consecutively ventilated with HFOV in the pediatric intensive care unit of a tertiary medical center, from January 2006 to February 2007. RESULTS A total of 20 patients were enrolled. The median a...

High-frequency oscillatory ventilation versus synchronized intermittent mandatory ventilation plus pressure support in preterm infants with severe respiratory distress syndrome.

BACKGROUND Mechanical ventilation and surfactants are the standard treatment of preterm respiratory distress syndrome (RDS). The effects of the primary ventilation model on bronchopulmonary dysplasia (BPD) and long-term neurodevelopment outcomes are controversial. The purpose of this study was to compare the efficacy and safety of high-frequency oscillatory ventilation (HFOV) and synchronized i...

High-frequency ventilation in acute pediatric respiratory failure.

High-frequency oscillatory ventilation in pediatric patients.

HFOV is a mode of ventilation that can achieve oxygenation and ventilation while maintaining maximal lung recruitment on the deflation limb of its pressure-volume curve. The primary theoretical advantages of HFOV over CMV in the management of acute lung injury are that HFOV allows adequate alveolar ventilation with minimal peak-trough pressure changes, provides lung recruitment, and avoids end-...
