Optimised Substitution Volume
High volume Haemodiafiltration has been shown to have survival benefits for a patient, therefore physicians prefer to set increased substitution volumes where possible.
However, it is difficult to define because higher volumes may also lead to excessive hemoconcentration and subsequent high transmembrane pressures or other related alarms
With the DBB-EXA, optimised substitution rate is automatically calculated when the nurse enters the Ultrafiltrate removal value (Quf).
When blood Flow, Haematocrit and Total Protein are downloaded from the Patient Card, DBB-EXA calculates an optimised Substitution volume (Qs) by using the Filtration Fraction of plasma water. If the TMP rises during treatment, the substitution rate is automatically reduced by the TMP Substitution Flow control.
TMP Sub control avoids alarms = less alarms leading to more trouble-free treatments, less workload for nurses, no need for further operator intervention during treatment and convenience for patients
This ultimately means an effective High Volume Haemodiafiltration treatment can be performed.
