Our objective was to compare two modes of high\u2010frequency ventilation, high\u2010frequency oscillation (HFOV), and high\u2010frequency percussive ventilation (HFPV) with conventional mechanical ventilation (CMV) in a piglet model of MAS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Fifteen newborn piglets were anesthetized, paralyzed, and intubated. Following the instillation of a 3\u2009ml\/kg solution of meconium diluted to 30%, the piglets were randomized to one of three groups: high\u2010frequency oscillation (HFOV; Sensormedics\u00ae), HFPV (Percussionaire\u00ae), or CMV (Siemens\u00ae). Animals were ventilated for 6\u2009hr to maintain arterial blood gases within a normal range, that is, pH 7.35\u20137.45, PaO<jats:sub>2<\/jats:sub> 10\u201316\u2009kPa, PaCO<jats:sub>2<\/jats:sub> 4\u20136.6\u2009kPa. Arterial blood gas measurements, dynCrs and dynRrs, ventilator settings, and vital signs (heart rate, arterial blood pressure, transcutaneous pulse oxygen saturation, and temperature) were collected at 30, 60, 90, 120, 180, 240, 300, and 360\u2009min after meconium instillation. Oxygenation index (OI) ([(fraction of inspired oxygen)(mean airway pressure)(100)]\/PaO<jats:sub>2<\/jats:sub>), mean airway pressure, dynamic lung function, secretions cleared and histological alterations were studied in all groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Mean airway pressure and OI were significantly lower in the CV and HFPV groups compared to the HFOV group (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05).
