It has been shown that the chest roentgenogram is a sensitive and accurate pool for detecting and quantitating cardiogenic pulmonary edema. This can be done at the interstitial stage, when it cannot be detected by physical examination. At the same time the chest film can provide useful information about the circulating blood volume. In patients with the ARDS, a characteristic peripheral and patchy distribution of alveolar edema associated with an absence of peribronchial cuffing, septal lines and effusions has been shown. Enlargement of the right side of the heart and main pulmonary artery may precede actual development of edema in ARDS and provide the opportunity for early diagnosis. Radiographic "scoring" in cases of ARDS correlates well with PO2 (measured with an F1O2 = .21) standardized to a PCO2 of 40 mm Hg. The three main forms of lung edema (that is, cardiogenic, renal or overhydration, and injury edema) appear to have radiographic features that can be used to separate them. The accuracy and objectivity of this approach has been confirmed by taking the radiographic signs as input variables for discriminant analysis. Different hemodynamic conditions and changes of the extravascular protein osmotic forces may be the main factors underlying the radiographic patterns in the various types of pulmonary edema. |
