Microprocessor control of perfusion during extracorporeal purification of physiological data

  • 11 Accesses

Conclusions

With the use of the proposed microprocessor system of controlling perfusion during extracorporeal purification of physiological media the following are achieved: concentration of the operator's attention on controlling the perfusate flow rate with simultaneous measurement of venous pressure; obtainment, if necessary, of additional information about the time of perfusion and about checking of venous and arterial pressures; a quantitative estimation of the perfusion parameters and of their monitored values in a digital form; simplification of control of perfusion by automation of the assignment of the monitored values of venous and arterial pressures; automatic indication of emergency situations with output of the indices characterizing deviation of the perfusion parameters from the assigned values on a display; conversational mode of assigning the perfusion regime.
