<qa>  What is the purpose of TBA Care?Patients undergoing intubation and mechanical ventilation require removal of secretion by means of trachoebronchial suctioning. Timing of the procedure is mainly based on clinical parameters. TBA Care is a new commercially available device designed to generate a signal when secretions are present in the respiratory tract of intubated patients, thus indicating the need for endotracheal suctioning only when necessary and prior to clinical deterioration. In a prospective randomized trial in intubated and mechanically ventilated patients of a general ICU the researchers investigated the efficacy of TBA Care in detecting the presence of retained secretions compared to the standard indicators.
