Reliability and performance of the IRRAflow® system for intracranial lavage and evacuation of hematomas—A technical note
Fig 3
IRRAflow® settings and physiological implications.
Pressure signals obtained at different IRRAflow® combinations of irrigation rate and drainage bag levels (A. 20/hour and 19 cm, 29cm and 39 cm, B. 90 ml/h and 19cm, 29cm and 39 cm and C. 180 ml/h and 19cm, 29cm and 39 cm (blue: Raumedic pressure signal, Red: IRRAflow® pressure signal). Error signals showing the pressure difference between the IRRAflow® and Raumedic pressure readouts are shown on the right side of each panel along with tables of the corresponding means and variances error in mmHg. The time required to achieve a stable chamber pressure varied with different settings and balanced fluid exchange required adjustment of drain bag to accommodate the irrigation rate.
