    Abstract: A face mask for delivering oxygen to, and sampling carbon dioxide exhaled from, a subject includes a partition wall that divides the mask into a subject respiratory space that primarily contains carbon dioxide exhaled by the subject, and an oxygen reservoir space that primarily contain oxygen. The partition wall includes one or two holes to which naris conduits are respectively connected. The naris conduit are positioned in proximity to the subject's nares to closely obtain carbon dioxide samples. The naris conduits enable oxygen to flow from the oxygen reservoir space to the subject respiratory space during inhalation, while quickly expelling traces of CO2, and they configured such that exhaled CO2 quickly fills them up, during exhalation, and while expelling oxygen traces back to the oxygen reservoir space. During exhalation.

    Abstract: A bypass filter comprising a conduit having a main passageway configured for passage of fluid from an upstream end of the conduit to a downstream end of the conduit; The bypass filter further comprises a main filter located within the main passageway and configured for preventing passage therethrough of a predetermined substance within the fluid, while allowing a remainder of the fluid to pass towards the downstream end of the conduit; The bypass filter has an upstream opening in the conduit located upstream of the main filter and being in fluid communication with the main passageway at an upstream end of the conduit and a downstream opening in the conduit located downstream of the main filter and being in fluid communication with the main passageway at a downstream end of the conduit; The bypass filter also comprises an auxiliary filter being in fluid communication with both the upstream opening and the downstream opening for passing the fluid between the openings while at least partially absorbing the substance.

    Abstract: A pneumatic system for delivering oxygen to a subject, including an oxygen supply channel having an inlet, a patient delivery outlet and an exhaust; and a flow control element configured to control the flow from the oxygen inlet to the patient delivery outlet, or to the exhaust; wherein inhalation by the patient causes the flow control element to assume a first position, allowing oxygen to flow from the oxygen inlet to the patient delivery outlet; and wherein exhalation by the patient causes the flow control element to assume a second position, directing oxygen flow from the oxygen inlet to the exhaust.

    Abstract: A CO2 monitoring system provides oxygen (O2) to a subject's mask with known characteristics. The CO2 monitoring system receives, from the mask, gas samples including exhaled CO2 diluted by O2. The CO2 monitoring system uses an adaptive noise canceller to cancel the diluting O2 by using the known characteristics of the O2 provided to the mask, the result of which process is restoration of the original concentration level of the CO2 as exhaled by the subject into the mask.
