  • Reason
    Risk of a gradual increased fluid removal, which may cause symptoms of hypotension during dialysis treatment. ultrafiltration deviations may not be immediately detected by the machine. this is due to a decrease in the residual moisture of the filter membrane, which can cause a higher fluid removal from the patient than initially selected. it has been noted that over time the residual moisture of the membrane used in the diacap ultra dialysis fluid filter decreases leading to an alteration in the membrane permeability, which in turn affects the device flow resistance. when used clinically, the altered functionality of the device can lead to excess fluid of up to 230 ml/hr, being removed under worst case conditions. although the haemodialysis system will alarm at a set value beyond the pre-set ultrafiltration rate, the higher ultrafiltration rate has the potential to cause symptoms of hypotension in some patients.
