    摘要: The present invention comprises a method for identifying the presence or absence of a pulmonary embolism using a combination of tests and brightline thresholds. The first test is a blood based test measuring D-Dimer concentration and the second test is a respiratory analysis that determines a carboximetry ratio. If the measured D-Dimer value is at or above a threshold indicative of concern and the carboximetry value is equal to or less than a carboximetry ratio threshold, pulmonary embolism is present. If the measured D-Dimer value is at or above a threshold indicative of concern and the respiratory analysis yields a carboximetry ratio greater than the carboximetry ratio threshold, test results are inconclusive and additional testing is required to determine whether a pulmonary embolism is present.

    摘要: An apparatus comprises a detector, a pressure sensor and a processor. The detector is operable to detect light that is scattered by an aerosol that is associated with a pressure. The pressure sensor is operable to measure the pressure. The processor is coupled to the detector and to the pressure sensor, and is configured to receive at least a signal from the detector and the pressure sensor. The processor is further configured to use the received signals to calculate a volume of the first aerosol, and to output an output signal associated with the calculated volume. The various measurements can be repeated and compared, and the output signal can be a feedback signal for metering subsequent amounts of the aerosol, based on the comparison.
