case_images: cDSAL circuit. (1) The normal waste line of the Spectra Optia is clamped with forceps, and the bleeding circuit of the TR-55X with the LA-40S is connected to the other end. (2) The blood return circuit connected to the Spectra Optia's replacement line by inserting a three-way stopcock. (3) Ringer's lactate solution attached to a regular replacement line as a buffer. "p" indicates the pressure gauge. Arrows indicate plasma flow.

case_images: A three-way stopcock was inserted into the Spectra Optia replacement line, Ringer's lactate solution was connected to the normal replacement line as a buffer, and the three-way stopcock was opened while using the replacement line (Fig. 1).
case_images: Removal rate/calcium concentration. a Removal rate for a plasma volume of 2,100 mL. b Calcium concentration at a plasma volume of 2,100 mL. Arrows indicate tube injection of 10 mL of calcium gluconate hydrate. Alb, albumin; Fib, fibrinogen; HDL, high-density lipoprotein; LDL, low-density lipoprotein; Plt, platelet; TG, triglyceride; TP, total protein.

case_images: In addition, the LDL removal rates for a plasma volume of 2100 mL were 61.9% and 59.4% for mDSAL and cDSAL, respectively, which were measured only once for each (Fig. 2a). However, during cDSAL, ionized calcium fell into the range of 0.75-0.89 mmol/L (measured by an ABL90 FLEX blood gas analyzer) at 75, 90, and 105 min after the start of treatment, which was addressed by infusion of 10 mL of calcium gluconate (Fig. 2b).
