Abstract
The invention relates to a device to determine effective pulmonary blood flow (PBF) by means of partial COrebreathing. The device is characterized in that it comprises an endotracheal tube whose conduit leading from the patient to the respirator is divided up into two lines between a controllabe three-way valve () and a Y-piece; one line forms a larger dead area () for COrebreathing whereby, in order to measure COelimination and end expiratory partial COpressure, a COsensor () and a respiration flow sensor () are provided on the endotracheal tube of the patient. The calculation of effective pulmonary blood flow is provided by a microprocessor/controller () which also controls the three-way valve () which provides the switching between both lines.
