ABSTRACT:
A method of determining the presence of pulmonary embolism is a postoperative patient using the carbox ratio of the patient prior to the surgical procedure and the carbox ratio of the patient after to the surgical procedure. The characteristics of the breath of the patient are obtained prior to a surgical procedure for a baseline and then afterwards if the patient has difficult breathing. The mean carbox ratios from the baseline and post-surgical data collections are then compared to non-invasively predict the likelihood that the patient has developed pulmonary embolism. A decrease in the carbox ratio of more than twenty-five percent (25%) represents an abnormal test and is consistent with possible pulmonary embolism. No change or an increase in the carbox ratio suggests the absence of pulmonary embolism.
