1. A patient monitoring system comprising:
- a fluid transport system configured to automatically draw a fluid sample from a patient at scheduled measurement times according to a sample draw schedule;
a fluid analyzer operatively connected to the fluid transport system and configured to determine a scheduled measurement of the concentration of an analyte in the fluid sample; and
a controller comprising a processor and a computer-readable medium encoded with instructions executable by the processor, the controller operatively connected within the patient monitoring system and configured to;
determine whether the scheduled measurement has failed;
cause the fluid transport system to draw an auxiliary fluid sample from the patient before the next scheduled measurement time when it is determined that the scheduled measurement has failed; and
determine an auxiliary measurement of the concentration of the analyte in the auxiliary fluid sample using the fluid analyzer.

Abstract
Disclosed are methods and apparatus for determining analyte concentration in a sample such as bodily fluid. Systems and methods disclosed herein can include an additive system for adding an additive to a sample to reduce the adverse affects of bubbles and microbubbles in the sample. Some systems and methods disclosed herein include performing an auxiliary measurement cycle in the event of a failure of a scheduled measurement cycle. Some systems and methods disclosed herein include a measurement system configured for use with multiple patients.

20. A method for monitoring a concentration of an analyte in a bodily fluid of a patient, the method comprising:
-
performing a scheduled measurement cycle intermittently at scheduled measurement times, the scheduled measurement cycle comprising; drawing a scheduled sample of bodily fluid from a patient into a fluid transport system; delivering at least a portion of the scheduled sample of bodily fluid to a fluid analyzer; measuring at least one characteristic of the at least a portion of the scheduled sample of bodily fluid; and determining a concentration of an analyte based at least in part on the at least one measured characteristic; determining whether the scheduled measurement cycle has failed; and performing an auxiliary measurement cycle before a next scheduled measurement cycle when it is determined that the scheduled measurement cycle has failed. - View Dependent Claims (21, 22, 23)
