1. A process for determining the amount of interaction in a mammalian lung between a breathable liquid in the lung and a respiratory gas flowing into and out of a pulmonary pathway in communication with the lung, said process comprising the steps of:

  • (a) sampling expired respiratory gas from the pulmonary pathway;

    (b) passing the sampled gas through a measurement detector, the detector outputting a discrete value representative of a property of the gas;

    (c) comparing the discrete value to previously determined discrete values representative of respiratory gas fully saturated with vapors of breathable liquid and respiratory gas unsaturated by vapors of breathable liquid; and

    (d) determining from the comparison the amount of interaction, wherein discrete values near the fully saturated discrete value indicates maximum interaction and discrete values near the unsaturated discrete value indicates minimum interaction.
