Arterial pressure monitoring….
Arterial blood pressure monitoring is the monitoring of blood supply from the patient and the pressure within the extra-corporeal blood circuit up to the dialyser. There are two arterial blood pressure monitoring that can be carried out, that is the pre-pump arterial blood pressure monitoring and the post-pump arterial blood pressure monitoring.
The Post-Pump Arterial Blood Pressure….
This method is commonly employed by most HDCs where the arterial blood pressure monitoring tubing is attached to the arterial chamber of the arterial bloodline set.
This method monitors the arterial blood pressure of the extra-corporeal blood circuit after the blood pump until the dialyser. The pressure monitored is the positive pressure exerted by the blood pump, pumping blood into the dialyser. This method will only detect any back pressure built-up as where the hollow-fibers in the dialyser begin to clot.
Since it will only detect clotting of the dialyser, most HDCs felt that there is no need to waste a transducer protector for its use.
