“…The same study also concludes that for patients with both predominantly upper-lobe emphysema and low base-line exercise capacity, LVRS reduces mortality. A more recent study shows the improvements in pulmonary function and exercise ability after LVRS [4], [5]. There are also studies that LVRS improves neuropsychological function and sleep quality [6].…”

Hyperspectral imaging system has been developed to characterize lung tissue for detecting emphysematous tissues in lung volume reduction surgery. The system consists of a charge-coupled device and liquid crystal tunable filter, which is continuously tunable in the near-infrared spectral range of 650 - 1100 nm with a mean bandwidth of 5 nm. Using hyperspectral data, the spectral signature of healthy lung tissue and simulated smokers lung tissue is obtained and compared. The data show the peak absorption intensity at four different wavelengths (760, 805, 915, and 970 nm). However, the reflectance intensity of simulated smoker's lung tissue over all spectral range is considerably higher than the normal lung tissue. The differences provide the basis for the detection and characterization of emphysema from healthy lung tissue.

“…The same study also concluded that, for patients with both predominantly upper‐lobe emphysema and low base‐line exercise capacity, LVRS reduced mortality. A more recent study showed improvements in pulmonary function and exercise ability after LVRS4, 5. Thus, LVRS clearly benefits patients with severe emphysema, and any improvements to the current LVRS procedure and equipment would be extremely valuable.…”
