    NON-INVASIVE DEVICE AND METHOD FOR THE DIAGNOSIS OF PULMONARY VASCULAR OCCLUSIONS
    (2005-04-19) Kline, Jeffrey A.
    The invention involves a device and method for ascertaining the functioning of the respiratory system and determining whether a pulmonary embolism is present. The device comprises an apparatus containing sensors which measure the amount of a particular gas expired from a patient's lungs, including a non-ambient gas which is previously provided to the patent. From this data, a processor computes the concentration of expired gas as a function of expired volume and displays the results on a screen. By comparing the results to predetermined values from afflicted and healthy patient populations, an accurate determination can be made regarding the presence of a pulmonary embolism.
