Excerpt
There is no valid estimation of the presence of airway secretions in mechanically ventilated patients. Secretions may amplify breath sounds by increasing turbulence in the airways or alternatively decrease breath sounds by obstructing air flow. Vibration response imaging (VRI) was recently suggested as a tool to assess secretion removal following physiotherapy [
1]. The objective of our analysis was to describe the acoustic effects of secretion removal by measuring the lung sound amplitudes pre and post airway suction in both lungs. …
