Claim:
1. A system configured to monitor the dead space fraction of a subject, the system comprising: a blood gas information interface configured to receive blood gas information related to one or more blood gas parameters that indicate concentrations of one or more molecular species in the blood of the subject; a respiration information interface configured to receive respiration information related to one or more respiration parameters of the breathing of the subject; and a processor configured to execute computer program modules, the computer program modules comprising: wherein the dead space fraction module is configured to determine the dead space fraction of the subject at measurement intervals such that, responsive to (i) blood gas information not being received by the blood gas information interface during a measurement interval, and (ii), respiration information being received by the respiration information interface during the measurement interval, the dead space fraction module determines the dead space traction of the subject at the end of the measurement interval based on values of the one or more blood, gas parameters used in a previous determination of the dead space fraction of the subject, and based on the values of the one or more respiration parameters obtained from the respiration information received during the measurement interval.
