摘要： There is accordingly provided a device for measuring a person's ventilation including oxygen consumption. The device includes a breathing conduit with at least one sensor sampling port. The device includes a dehumidification conduit extending from the sensor sampling port towards a sensor. The dehumidification conduit has a proximal end portion flush with the sensor sampling port. The dehumidification conduit has a longitudinal axis about which the proximal end portion thereof extends. The breathing conduit is shaped to promote a flow of air adjacent the sensor sampling port in one or more directions perpendicular to the longitudinal axis.

摘要： There is provided a device for measuring a user's oxygen-consumption. The device includes a tubular member with a first tapered portion through which an exhalation of air enters into the device, a second tapered portion, and a constriction between the portions thereof. The devices includes a flow sensing mechanism in communication with the first tapered portion of the tubular member. The device includes an oxygen sensor in communication with the first tapered portion of the tubular member. The device is configured such that the oxygen sensor is passively supplied a portion of the exhalation of air by means of positive or negative differential pressure referenced between the first tapered portion and at least one of ambient air and the constriction of the tubular member.

摘要： There is provided a device for measuring a user's oxygen-consumption. The device includes a venturi tube. The venturi tube has a first tapered portion, a second tapered portion that is more tapered compared to the first tapered portion, and a constriction between the portions thereof. The device includes at least one pressure sensor in communication with the constriction and the first tapered portion of the venturi tube. The device includes an oxygen sensor in communication with the constriction and the first tapered portion of the venturi tube.
