These effects were noted in both hemithoracies (Figure (Figure2C2C). Figure 2 Representative vibration response imaging images and chest radiographs. A, Healthy volunteer.

D, Mechanically ventilated CHF … Geographic Area and Vibration Energy of Respiratory Sounds The median geographic area of
each maximal inspiratory vibration energy image was calculated. In healthy volunteers, themedian (IQR) geographical area of the vibration energy image was 76.2 (6.0) kilo-pixels. Inhibitors,research,lifescience,medical On admission, areas for CHF patients without REPE and those with REPE were66.9 (9.0) and 64.1(9.0), respectively (p < 0.05) (Figure (Figure3).3). On admission, the geographical area in CHF patients without and with REPE was
significantly lower compared to the geographical area of healthy volunteers (p < 0.05). After clinical improvement, the geographic area increased to 71.9 (12.0) and 73.4 (12.0) kilo-pixels Inhibitors,research,lifescience,medical in patients without REPE and with pulmonary edema, respectively Inhibitors,research,lifescience,medical (Figure (Figure4).4). This corresponded to increases in area of 18 ± 15% (p < 0.01) and 25 ± 16% (p < 0.01), in the without REPE and with REPE patients, respectively. The total vibration energy values were calculated in each group on admission and were found to be significantly higher in CHF patients with REPE compared to those without REPE and healthy volunteers (Figure (Figure5)5) (p < 0.05 between edema group and others). Total vibration energy decreased in CHF patients Inhibitors,research,lifescience,medical with REPE following clinical improvement by an average of 90 ± 11% (p < 0.01) but remained unchanged in CHF patients without REPE (Figure (Figure66).
