摘要： 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.

摘要： A device for measuring a concentration of a component in a target sample includes a flow chamber with a first channel that receives a reference sample having a known concentration of the component. The flow chamber also includes a second channel that receives the target sample having an unknown concentration of the component. A pump operates to pump the reference sample and the target sample at a same volume flow rate through the first and second channels, respectively. A thermal mass flow meter measures a thermal conductivity of the reference sample, a thermal conductivity of the target sample, or both.

摘要： A device for reconstituting a filter and/or a filter-containing consumable for use in breath monitoring, the device including a connector socket that may receive and/or mate with the filter or filter-containing consumable, a pump that may pump ambient air into a chamber of the device, an inlet that may allow flow of oxygen into the chamber, a UV source that may catalyze the formation of ozone from the oxygen, thereby obtaining ozone enriching air in the chamber, and an outlet that may eject the ozone enriched air, from the chamber, into the filter, thereby reconstituting the filter and/or the filter-containing consumable.

摘要： There is provided herein methods, apparatus and systems for evaluating carbon dioxide (CO2) concentration in a subject's breath, for example in subjects ventilated with High Frequency Ventilation (HFV), the method includes inserting to a trachea of a subject an endotrachial tube (ETT), sampling breath from an area in the trachea located in proximity to a distal end of the endotrachial tube (ETT) and evaluating one or more CO2 related parameters of the sampled breath.

摘要： A ventilation analysis system comprising an interface module adapted to receive a carbon dioxide (CO2) signal and a breath flow dynamics signal, and control logic adapted to produce a ventilation indicator, based on a mutual analysis of the CO2 signal and the breath flow dynamics signal. The ventilation indicator may be, for example, an estimated CO2 waveform, an End-Tidal CO2 (ETCO2) value, and/or a minute CO2 value.
