This article presents specific uses of the portable chest film. The specific utility, borderline utility, and pitfalls in interpretation of films that are often taken to investigate a number of diagnostic problems common to the practice of emergency medicine are discussed.
A basic review is presented of the anatomy and physiology of the airways and the alveolar - capillary interface. Lung volumes are defined, as are terms used in pulmonary function testing, and alveolar ventilation is discussed. Five common mechanisms of arterial hypoxemia are explored and some common examples are presented, and the value and limitations of arterial blood gas determinations and pulse oximetry in the Emergency Department setting are discussed.
Integration of the principles of triage in the radiographic assessment of the trauma victim should allow efficient and timely diagnosis of most serious injuries. Use of the portable apparatus is stressed as the initial approach, but caution must be exercised in the exclusion of significant injuries by this method. Careful reading of additional information on films taken for a primary reason may allow the early diagnosis of associated problems (e.g., evaluating the upper airway on cervical spine views and the diaphragms on a chest film). Close cooperation between the emergency physician and radiologist is important in order to obtain the highest diagnostic accuracy in caring for victims of multiple trauma.
