TY - JOUR T1 - Ventilator Auto-Triggering in a Patient with Tuberculous Bronchopleural Fistula JF - Respiratory Care SP - 519 LP - 521 VL - 48 IS - 5 AU - Jeffrey S Sager AU - Glenn Eiger AU - Barry D Fuchs Y1 - 2003/05/01 UR - http://rc.rcjournal.com/content/48/5/519.abstract N2 - We report a case of ventilator auto-triggering resulting from tuberculous bronchopleural fistula being managed with chest tube suction. Early recognition of bronchopleural fistula-related auto-triggering is extremely important. Auto-triggering can lead to serious adverse effects, including severe hyperventilation and inappropriate escalation of sedatives and/or neuromuscular blockers (administered to reduce spontaneous breathing efforts). Auto-triggering was confirmed in our patient when tachypnea persisted despite pharmacologic neuromuscular paralysis. Auto-triggering can be reduced or eliminated by decreasing ventilator trigger sensitivity or by decreasing the air leak flow by reducing the degree of chest tube suction. ER -
