Document: The experimental program was carried out at the Biotechnology Laboratory at the University of South Africa, Johannesburg. This facility is at an altitude of 1700 m, with atmospheric pressure of 84 kP a, and the ambient room temperature was approximately 25 0 C A Leoceed-N21 (Asahi Kasei Medical) hollow fiber membrane dialyser unit intended for renal dialysis was used in this study. This device has a polysulfone membrane with an e ective surface area of 2.1 m 2 , priming volume of 108 ml, and an internal fibre diameter and wall thickness of 185 µm and 35 µm respectively. The manufacturer-specified maximum blood flow rate is 500 ml · min ≠1 , and the maximum transmembrane pressure (TMP) is rated at 80 kP a.
