substantial body of evidence has shown that extracorporeal blood oxygenators alter blood in some way that eventually A damages the perfused tissue [8, 111.Some authors have suggested that microemboli are responsible, but detecting the presence of microemboli has been difficult [l, 4-7, 121.Recently a detection chamber employing ultrasound has been developed which continuously counts particles in flowing blood which are greater than 50 p [9].Using this apparatus, a study was made of the relative concentration of microemboli produced by a disc oxygenator, a membrane oxygenator, and two types of disposable bubble oxygenators.The findings are reported here.
