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...

BACKGROUND High frequency oscillatory ventilation (HFOV) is considered a protective strategy for human lungs. This study was designed to define microscopic structural features of lung injury following HFOV with a high lung volume strategy in newborn piglets with acute lung injury. METHODS After acute lung injury with saline lavage, newborn piglets were randomly assigned to 5 study groups (6 i...

CV and usually in the first 12 h of life. Data Collection and Analysis: The methodological quality of each trial was independently reviewed by the various authors. The standard effect measures are relative risk (RR) and risk difference (RD). From 1/RD the number needed to treat to produce one outcome were calculated. For all measures of effect, 95% confidence intervals were used. In subgroup an...
متن کاملElective High-Frequency Oscillatory Ventilation Versus Conventional Ventilation for Acute Pulmonary Dysfunction in Preterm Infants
BACKGROUND Respiratory failure due to lung immaturity is a major cause of mortality in preterm infants. Although the use of intermittent positive pressure ventilation (IPPV) in neonates with respiratory failure saves lives, its use is associated with lung injury and chronic lung disease. A newer form of ventilation called high frequency oscillatory ventilation has been shown in experimental stu...

We thought it was impossible. Physiological principles maintained that ventilation at tidal volumes less than the anatomical deadspace should be ineffective (i.e., inspired air not reaching the alveolae). Data from a 1980 study dispelled that myth, showing unequivocally that ventilation with tidal volumes as small as 20 to 30 ml in dogs, a mere fraction of the anatomical deadspace, could mainta...
