1. An effort-independent, portable, user-operated capnograph device, comprising:
- a sensor for sensing concentrations of carbon dioxide (CO2) exhaled by a user when breathing normally;
a memory for storing data of the sensed concentrations of CO2 and one or more baseline measurements; and
an analyzer for comparing the stored data with at least one of the baseline measurements to determine the pulmonary status of the user; and
an output device for indicating the pulmonary status to the user.

Abstract
An effort-independent, portable, user-operated capnograph device for evaluating a pulmonary status of a user. At least one baseline measurement is stored within a memory of the capnograph device. The identity of a user of the capnograph device is verified to prevent miss-use. Concentrations of carbon dioxide (CO2) exhaled by the user when breathing normally are sensed and stored within the memory. The stored data is compared with the at least one of the baseline measurements to determine the pulmonary status of the user, and the determined pulmonary status is indicated to the user.
