A double lumen cannula was specially devised for duplicate purposes of blood drainage to a dialyzer and continuous monitoring of intravascular pressure of the fistulated vein created as a blood access for hemodialysis.
An experiment evidenced that there exists a statistically significant relationship between the fistulated venous pressure and the systemic arterial pressure. During clinical hemodialysis, the fistulated venous pressure reduced concurrently with systemic pressure reduction.
It is concluded that monitoring of the fistulated venous pressure can be substitutional for that of the systemic arterial pressure from a standpoint of clinical patient care.
