Figure 5From: Respiratory sound energy and its distribution patterns following clinical improvement of congestive heart failure: a pilot study Vibration energy during maximal inspiration in healthy volunteers, acute CHF exacerbation patients without and with REPE and CHF patients with REPE mechanically ventilated. CHF, congestive heart failure. REPE, radiographically evident pulmonary edema.* = higher vibrational energy when compared to normal controls (P < 0.05).Back to article page
