Abstract:
1. A method of monitoring performance of a fluid testing system having a sensor, a patient connection adapted to connect the system to a patient to collect a fluid sample, a pump, a processor in communication with a memory, and a flushing fluid connection adapted to connect the system to a flushing fluid to flush the system after a fluid test, the method comprising: drawing a fluid sample from the patient via the patient connection using a pump of the testing system to draw the fluid sample from the patient to the testing system: generating a voltage output of a sensor indicative of a fluid present at the sensor; comparing the voltage output of the sensor during the drawing of the fluid sample to an upper fluid volume drawn based voltage limit and a lower fluid volume drawn based voltage limit stored within a memory in communication with a processor; flushing the system with a flushing fluid using the pump of the testing system to flush the flushing fluid from the testing system; comparing the voltage output of the sensor during the flushing of the flushing fluid to an upper fluid volume flushed based voltage limit and a lower fluid volume flushed based voltage limit stored within the memory in communication with the processor; and generating an alert if at least one of the voltage output during the drawing of the fluid sample is outside of the lower fluid volume drawn based voltage limit and the upper volume drawn based voltage limit and the voltage output during the flushing of the flushing fluid is outside of the lower fluid volume flushed based voltage limit and the upper fluid volume flushed based voltage limit.
