The common pathogens in nosocomial pneumonia are aerobic gram negative organisms and Staphylococcus aureus.82 Gram negative pneumonias have become much more frequent over the past two decades due…

    Discussion   The portable film reveals infiltrates bilaterally. Note the basilar position of the infiltrates, quite characteristic of a patient who has been intubated for a long period…

    Discussion   The film now reveals persistent left lower lobe and left upper lobe pneumonia. Note the obliteration of most of the left cardiac border, secondary to the…

    Discussion   Portable film reveals the heart to be at the upper limits of normal. Note the classic appearance of pulmonary edema with bilateral perihilar fluid, loss of…

    Discussion   This patient’s film reveals an extensive confluent infiltrate in the right lower lung field. One could assume that this represents an extensive pneumonia. There are however,…

    Cardiac catheterization can also be a relatively common cause of pneumothorax; its incidence after subclavian vein puncture is between 0.3% and 3%, but it almost never occurs after…

    Milne and colleagues110 demonstrated that one can obtain a large amount of useful hemodynamic information from consideration of the vascular pedicle width (VPW).   VPW is often important…

    Even in patients who are on mechanical ventilation, obstructive atelectasis can occur very rapidly. One theory is that highly oxygenated air, as opposed to normal ambient air, is…

    Figure 8.2 The coalescence of many of the patchy areas of infiltrate are seen throughout both lung fields, which eventually will create a more homogenous and extensive infiltrate….

    This is due to an area of pulmonary infarction secondary to the embolis. Remember, many cases of pulmonary emboli do not produce associated infarction. Effusions occur in about…
