Title:

BREATHING CIRCUITS TO FACILITATE THE MEASUREMENT OF CARDIAC OUTPUT DURING CONTROLLED AND SPONTANEOUS VENTILATION

Document Type and Number:

WIPO Patent Application WO2004073779

Kind Code:

A3

Abstract:

A breathing circuit for use with a first gas set (FGS) and a second gas set (SGS), said circuit comprising means for keeping separate the FGS and SGS, and a means for sequentially delivering to a patient, first the FGS, and, on inspiration, when the patient inspires so as to deplete the supply of FGS into the circuit, subsequently delivers substantially SGS for the balance of inspiration.
