The TBA Care acoustic secretion detector module connects to a sensor at the Y-piece. When secretions are detected in the airway the module generates an acoustic and visual signal.

Secretions collected during endotracheal suctioning, measured with a semi-quantitative method. 0 = no secretions collected (unnecessary suctioning), 1 = scarce, 2 = few, 3 = moderate, 4 = abundant. All the difference are statistically significant.

Indications for the suctionings that collected no secretions.
- Fig. 5.
Indications for all the suctionings. Routine = scheduled suctioning, which occurred only in the control group, once per shift (ie, at least 3 times a day). Dyspnea = dyspnea or cough or apparent increased work of breathing Auscultation = coarse breath sounds on auscultation. > PIP = increased peak inspiratory pressure during volume controlled or pressure controlled volume guaranteed ventilation. < VT = decreased tidal volume during pressure controlled ventilation. Visible secretions = visible secretions in the endotracheal tube or ventilator circuit. < SpO2 = SpO2 decrease not otherwise explained. Other = clinical reasons other than the previous. In all the categories the difference was significant.

Number of suctioning passes. The first 1, 2, or 3 passes were always with the closed suctioning system. If more than 3 passes were required, the operator changed to the open suctioning system. All the difference are statistically significant.
