AbstractPartial or total obstruction of an endotracheal tube (ETT) by mucus can cause severe respiratory distress, hypoxemia, or death. Signs of an obstructed ETT include increased ventilation pressure, changes in the ventilator graphics, S(pO(2)) decrease, and cardiovascular changes. We present 3 patients whose ETTs were partially obstructed by mucus. In each case the patient displayed adverse effects from the obstruction, but once the obstruction was removed they showed dramatic improvement. In each case we used a new device (Rescue Cath, Omneotech, Tavernier, Florida) designed to remove mucus from the ETT lumen. The 3 cases demonstrate that the device is effective and capable of relieving the adverse effects of ETT mucus obstruction.
