  • Breath Monitoring Apparatus and Method
    Publication number: 20080161709
    Abstract: A breath monitoring apparatus is provided comprising a housing (4) on which is mounted, a means (6, 10, 12) to measure the volume of an inhaled breath of the user; and a means (8) to measure the gas content of an exhaled breath of a user. There is further provided a method of monitoring breaths, the method comprising the steps of calculating the volume of an inhaled breath of a user and calculating the gas content of an exhaled breath of the user. The apparatus and method relate in particular to indirect calorimetry.

  • Respiratory Metabolic Rate Measurement Apparatus
    Publication number: 20070213628
    Abstract: A (8, 6, 10, 12, 14) metabolic rate measuring apparatus comprising means to measure a reference metabolic rate of a user from at least one breath of the user, means to measure metabolic rate from a subsequent breath of a user, means (14) to indicate a deviation from the reference rate in a breath and prevent measuring of subsequent breaths, and means (50) for a user to override the measurement prevention means to enable measurement of metabolic rate from breaths which deviate from the reference rate.
