Figure 7From: Respiratory sound energy and its distribution patterns following clinical improvement of congestive heart failure: a pilot study In mechanically ventilated CHF patients with radiographically evident pulmonary edema, geographical area (A) of vibration energy images increases and vibration energy (B) during maximal inspiration decreases after clinical improvement (* = P < 0.05). Each color/line represents a patient. CHF, congestive heart failure. REPE, radiographically evident pulmonary edema.Back to article page
