1 Effects of an automated endotracheal-tube-compensation system on a pressure-support breath.
Effects of an automated endotracheal-tube-compensation system on a pressure-support breath. Column A shows a typical pressure-support breath. Note that the airway (circuit) pressure curve has the desired square wave shape, but this is distorted by the endotracheal-tube resistance to a more gradually rising pressure profile in the trachea. In contrast, with an automated endotracheal-tube-compensation system (pressure support plus automatic tube compensation, column B), the airway (circuit) pressure is automatically adjusted to create the desired square wave of pressure in the trachea.
