    摘要： An apparatus to measure cardiac output (Q) and other parameters such as alveolar ventilation (VA), minute CO2 elimination from the lung (VCO2 ), minute oxygen consumption (VO2), oxygenated mixed venous partial pressure of CO2, (PvCO2-oxy), true mixed venous partial pressure of CO2(PvCO2), PaCO2, mixed venous oxygen saturation (SvO2), pulmonary shunt, and anatomical dead space, consisting of: a) a breathing circuit with characteristics that: i. on exhalation, exhaled gas is kept substantially separate from inhaled gas; ii. oninhalation, when VE is greater than FGS flow, the subject inhales FGS first and then inhales a gas that is substantially SGS, for the balance of inhalation; b) gas sensor means for monitoring gas concentrations at the patient-circuit interface c) a first gas set (FGS), and a second gas set (SGS), said second gas set which may comprise previously exhaled gases or exogenous gases or both d) a gas flow control means for controlling the rate of FGS flow into the breathing circuit e) means to identify phase of breathing, said means may consist of pressure sensors or analysis of signal generated by gas sensors or other means known to those skilled in the art; f) machine intelligence consisting of a computer or logic circuit capable of controlling the gas flow control means, receiving the output of the gas sensor means and means to identify phased of breathing, and performing the calculations for measuring cardiac output and other parameters as outlined in the disclosure.

    摘要： A particulate blocking oxygen delivery mask includes a face piece constructed at least partially of a filtering material, a securing member such as a strap attached to the face piece, and an gas entry port disposed on the face piece. The gas entry port may include an optional one-way valve. The mask may be coupled to a continuous flow of oxygen or may be used as a partial or non-rebreathing mask. The mask permits the administration of high concentrations of oxygen to the patient while at the same time isolating the patient from any potentially contagious airborne particles in their surroundings. It also isolates any potentially contagious droplets or aerosolized particulate matter exhaled by a patient from entering the environment and potentially infecting others.
