The effect of Positive End Expiratory Pressure (PEEP) on the hepatic elimination of low to moderate extraction ratio drugs has not been clearly defined. We prospectively investigated the effect of PEEP on the clearance of theophylline in 30 (20 males and 10 females) intubated critically ill adult patients with acute lung injury/acute respiratory distress syndrome (ALI/ARDS). The Mean (±SD) age ...

We present a new set of experiments in local scour due to confined twin propeller jets aiming include driving characteristics the analysis scouring action during in-port manoeuvres. The maximum depth is studied as function bed clearance, wall clearance and efflux velocity jet. Aiming reproduce more realistic manoeuvres, both forward backward rotation propellers are analysed showing different be...
