Abstract
The present disclosure relates to a method for determining or recommending a time point for measuring a patient's pressure readings during a blood treatment session. The method encompasses monitoring the ultrafiltration rate with which the patient's blood is treated, a relative blood volume, and/or a sodium concentration or a change in any of these, for the existence of, or meeting any pre-determined criterion for the ultrafiltration, the relative blood volume, and/or the sodium concentration, or the change thereto. Furthermore, the method encompasses transmitting a signal to a blood pressure measuring device when the pre-determined criterion for the ultrafiltration rate, the relative blood volume, and/or the sodium concentration or the change thereto is met.
Claims24
A method for determining or recommending at least one time point for measuring pressure measurements on a patient during a treatment session in which the patient's blood is treated extracorporeally via a blood treatment apparatus, the method comprising:
- monitoring, during the treatment session, one or more of an ultrafiltration rate with which the patient's blood is treated and a sodium concentration for one or more changes in one or more of the ultrafiltration rate and the sodium concentration, respectively, or for fulfilling one or more pre-determined criteria, respectively, for one or more of the ultrafiltration rate and the sodium concentration;
- and
- transmitting a signal to a blood pressure measuring device when any of the one or more pre-determined criteria or any of the one or more changes are met, respectively, for one or more of the ultrafiltration rate and the sodium concentration,
- wherein the signal comprises an instruction for measuring a blood pressure of the patient at an end point of a peak of a plurality of peaks of a treatment profile of the ultrafiltration rate or of the sodium concentration or at an end point of a valley of a plurality of valleys of the treatment profile.
A control device or closed-loop control device configured to carry out mechanical steps of a method for determining or recommending at least one time point for measuring pressure measurements on a patient during a treatment session in which the patient's blood is treated extracorporeally via a blood treatment apparatus, the method comprising:
- monitoring, during the treatment session, one or more of an ultrafiltration rate with which the patient's blood is treated and a sodium concentration for one or more changes in one or more of the ultrafiltration rate and the sodium concentration, respectively, or for fulfilling one or more pre-determined criteria, respectively, for one or more of the ultrafiltration rate and the sodium concentration;
- and
- transmitting a signal to a blood pressure measuring device when any of the one or more pre-determined criteria or any of the one or more changes are met, respectively, for one or more of the ultrafiltration rate and the sodium concentration,
- wherein the signal comprises an instruction for measuring a blood pressure of the patient at an end point of a peak of a plurality of peaks of a treatment profile of the ultrafiltration rate or of the sodium concentration or at an end point of a valley of a plurality of valleys of the treatment profile.
A medical set comprising:
- a blood pressure measuring device;
- and
- a control device or closed-loop control device configured to carry out mechanical steps of a method for determining or recommending at least one time point for measuring pressure measurements on a patient during a treatment session in which the patient's blood is treated extracorporeally via a blood treatment apparatus, the method comprising:
- monitoring, during the treatment session, one or more of an ultrafiltration rate with which the patient's blood is treated and a sodium concentration for one or more changes in one or more of the ultrafiltration rate and the sodium concentration, respectively, or for fulfilling one or more pre-determined criteria, respectively, for one or more of the ultrafiltration rate and the sodium concentration;
- and
- transmitting a signal to a blood pressure measuring device when any of the one or more pre-determined criteria or any of the one or more changes are met, respectively, for one or more of the ultrafiltration rate and the sodium concentration,
- wherein the signal comprises an instruction for measuring a blood pressure of the patient at an end point of a peak of a plurality of peaks of a treatment profile of the ultrafiltration rate or of the sodium concentration or at an end point of a valley of a plurality of valleys of the treatment profile.
