RATIONALE Mechanical ventilation is known to induce ventilator-induced diaphragm dysfunction. Patients submitted to mechanical ventilation often receive massive doses of corticosteroids that may cause further deterioration of diaphragm function. OBJECTIVES To examine whether the combination of 24 hours of controlled mechanical ventilation with corticosteroid administration would exacerbate ve...

The most commonly used mode of noninvasive mechanical ventilation (NMV) is volume-controlled intermittent positive pressure ventilation (IPPV). Pressure support ventilation has recently become increasingly popular, but its merits have not been clearly defined. In an open, nonrandomized follow-up study, we evaluated two modes of NMV, volume-controlled (IPPV) and pressure-controlled ventilation (...

Llewellyn, M. A., Tilak, K. S., and Swyer, P. R. (1970). Archives of Disease in Childhood, 45, 453. A controlled trial of assisted ventilation using an oro-nasal mask. A controlled study was performed to assess the effect of early assisted ventilation using a tight fitting face mask. Early mask ventilation reduced the number of infants requiring intubation, but did not significantly alter the s...

PURPOSE Right internal jugular vein (RIJV) catheterisation is a common procedure in patients undergoing surgery. We aimed to compare diameters and the cross-sectional area (CSA) of the RIJV when the head is in a neutral or 30-degree rotated position during mechanical ventilation in various modes and spontaneous ventilation. METHODS Thirty patients undergoing surgery were included in the study...

OBJECTIVE To explore the effects of ventilatory mode "pressure controlled ventilation-volume guaranteed" (PCV-VG) on the inspiratory pressures, oxygenation parameters and hemodynamics of patients during one lung ventilation (OLV) for thoracic surgery, compared with volume controlled ventilation (VCV). METHODS Twenty participants were recruited and equally assigned into two groups in a control...
