Abstract
A system for measuring a mass of exhaled carbon for weight loss monitoring. The system includes a capture device for capturing exhaled breath and determining a mass of carbon in the exhaled breath, a respiratory inductive plethysmograph (RIP) device incorporated into apparel, and a processor incorporated into a computing device. Mass of exhaled carbon may be determined by the capture device and computing device alone. Alternatively, mass of exhaled carbon may be determined by the RIP device and the computing device alone, after calibration of the RIP device using the capture device.
Claims15
A system for monitoring respiration, comprising:
- a capture device, the capture device comprising a first device configured to detect a volume of air expelled during a breath, and a second device configured to detect a concentration of carbon dioxide in the breath;
- a device incorporated into apparel or to be worn by itself around a chest and/or abdomen, the device configured to detect volumetric changes in the chest and/or abdomen during breathing;
- and
- a computing device configured to execute a first algorithm to:
- receive the volume of air expelled during the breath from the capture device,
- receive the concentration of carbon dioxide in the breath from the capture device, and
- determine a mass of the carbon exhaled in the breath using the received volume of expelled air and concentration of carbon dioxide in the breath;
- and
- the computing device configured to execute a second algorithm to:
- receive the volume of air expelled during the breath from the capture device,
- receive the concentration of carbon dioxide in the breath from the capture device,
- receive the volumetric changes in the chest and/or abdomen during the breath,
- correlate a volumetric change in the chest and/or abdomen with an amount of air expelled during the breath, and
- determine a mass of the carbon exhaled in the breath using the correlated change in chest and/or abdomen volume and concentration of carbon dioxide in the breath.
A method of monitoring respiration, comprising:
- a) detecting a volume of air expelled during a breath using a first device;
- b) detecting a concentration of carbon dioxide in the breath using the first device;
- c) detecting volumetric changes in a chest and/or abdomen during breathing using a second device;
- d) determining a mass of carbon exhaled in the breath using the received volume of expelled air and concentration of carbon dioxide in the breath from the first device;
- e) calibrating the second device using and the received volume of expelled air as detected by the first device;
- and
- f) determining a mass of carbon exhaled in the breath using volumetric changes in a chest and/or abdomen during breathing from the second device after said step (e) of calibrating the second device.
