| 摘要 |
A monitoring device receives a measurement signal obtained by a pressure sensor in an extracorporeal fluid system, such as an extracorporeal blood circuit for a dialysis machine which is in contact with a vascular system of a subject via a fluid connection. The monitoring device processes the measurement signal to identify pressure data that represents pulses originating from a first physiological phenomenon in the subject, excluding the heart of the subject. The first physiological phenomenon may be any of reflexes, voluntary muscle contractions, non-voluntary muscle contractions, a breathing system of the subject, an autonomous system of the subject for blood pressure regulation, or an autonomous system of the subject for body temperature regulation. The monitoring device may detect, present, track or predict a disordered condition of the subject using the pressure data, or monitor the integrity of the fluid connection based on the pressure data. |
