We report a patient who received a right single lung transplant (SLT) for progressive lymphangioleiomyomatosis and required reintubation for postoperative respiratory distress. She developed hemodynamic instability due to mediastinal shift from unilateral auto-PEEP with hyperinflation of the native lung. Placement of a double lumen endotracheal tube (DLET) and institution of differential lung ventilation restored equal lung inflation and hemodynamic stability. 相似文献

We show that a broad class of visual illusions, including illusory motion, can be explained by the effects of negative afterimages. Two new illusions, illusory shading and illusory tilting, are devised on the basis of the proposed explanation. The general feature of these illusions is an alternation between a high-contrast (white or black) and a low-contrast (gray) local input signal, which can be caused either by eye motion over patterns of varied luminance or by a change in such patterns over time. A simple model of the local signal dynamics qualitatively reproduces the illusory effects by adding the negative afterimage to the original visual stimulus. 相似文献
