Abstract
To examine the phenomenon of inappropriate triggering caused by an in-line suction catheter. We used a test lung to assess inappropriate triggering in four ventilators with both pressure and flow triggering. With pressure triggering, inappropriate triggering occurred only in the presence of PEEP. However, with flow triggering, inappropriate triggering occurred both with and without PEEP. Inappropriate triggering did not occur in a model of severe airflow obstruction. In-line suction catheters may lead to inappropriate triggering and potentially dangerous increases in delivered ventilation.
