ABSTRACT:
A method for raising or lowering the fluid level in a chamber in an extracorporeal circuit of a dialysis machine, such as an air trap or compliance chamber, is provided which uses a touch screen. The user of the machine is prompted to indicate on the touch screen the current or actual level of fluid (e.g., blood) in the drip chamber. The user then touches the touch screen to indicate the level, such as by touching an illustration of the chamber at a level corresponding to the actual level. The control system for the machine determines from the level indicated on the touch screen whether the level in the chamber needs to be raised or lowered, and by how much, and responsively operates chamber level adjustment apparatus (such as pressure adjustment apparatus in air communication with the chamber) to raise or lower the level closer to the proper level.
