Method of monitoring a dialysis unit

A dialysis treatment method comprising the steps of:

• storing in a first memory location desired values for a plurality of treatment parameters relating to a treatment to be carried out, at least one of the plurality of parameters being a controlled parameter having an initial value, the plurality of treatment parameters corresponding to a desired clinical prescription;
• detecting, during a treatment session, current values of said plurality of treatment parameters;
• comparing the current values with the stored desired values;
• calculating a suggested value of the controlled parameter to maintain the clinical prescription when at least one of the current parameter values differs from a corresponding desired value;
• comparing the suggested value of the controlled parameter with the initial value of the controlled parameter to determine a difference;
• determining whether the suggested value of the controlled parameter falls within a threshold range when an absolute value of the difference is greater than a predetermined value;
• generating a warning signal indicating that the current values are not in accordance with the desired clinical prescription when the suggested value of the controlled parameter falls outside of the threshold range;
• and
• adjusting the controlled parameter to substantially maintain the desired clinical prescription by replacing the initial value of the controlled parameter with the suggested value of the controlled parameter when the suggested value of the controlled parameter falls within the threshold range.

A dialysis treatment method comprising the steps of:

• conducting blood through a blood side of a dialysis unit during a treatment session;
• withdrawing a used fluid from a used fluid side of the dialysis unit during the treatment session;
• storing in a first memory location desired values for a plurality of dialysis treatment parameters relating to a treatment to be carried out by the dialysis unit during the treatment session, at least one of the plurality of parameters being a controlled parameter having an initial value, the plurality of dialysis treatment parameters corresponding to a desired clinical prescription;
• detecting, during the treatment session using the dialysis unit, current values of said plurality of dialysis treatment parameters;
• comparing the current values with the stored desired values;
• calculating a suggested value of the controlled parameter to maintain the clinical prescription when at least one of the current parameter values differs from a corresponding desired value;
• comparing the suggested value of the controlled parameter with the initial value of the controlled parameter to determine a difference;
• determining whether the suggested value of the controlled parameter falls within a threshold range when an absolute value of the difference is greater than a predetermined value;
• generating a warning signal indicating that the current values are not in accordance with the desired clinical prescription when the suggested value of the controlled parameter falls outside of the threshold range;
• and
• adjusting the controlled parameter to substantially maintain the desired clinical prescription by replacing the initial value of the controlled parameter with the suggested value of the controlled parameter when the suggested value of the controlled parameter falls within the threshold range.
