## Indications for use
The CSAM CKHEMO rev 1.0 software computer program is a stand-alone product used to calculate total urea clearance (Kt/V), total urea clearance (Kt/V) delivered using the natural log formula, residual renal urea clearance (KrU), normalized protein catabolic rate (NPCR), actual blood flow, urea reduction ratio, body water volume calculated by urea kinetic modeling, total body water volume calculated using Watson's formula, actual weight loss after treatment, percent deviation (%Dev), and treatment time. These values are calculated using the test results of blood drawn immediately prior to and upon completion of kidney hemodialysis treatment based on the existing scientific formulas for single pool urea kinetic modeling. The device software is not meant to serve as the sole tool for determining effectiveness of treatment but as an adjunct to assist the physician in making the determination.
