Assessment of a respiratory condition of a subject, by acquiring a temporally varying hemodynamic waveform signal related to blood flow in a tissue; deriving from the hemodynamic waveform signal an evaluation of blood CO2; acquiring at least one more signal; and determining the medical condition based on the blood CO2 and the at least one more signal. A device for performing the assessment may include an implement disposable on the subject's skin and structured to acquire a temporally varying hemodynamic waveform signal and derive from the signal a blood CO2 value or a close approximation thereof; an oximeter disposable on the subject's skin and structured to provide an oxygen saturation value of the blood of the subject or a close approximation thereof; and an apparatus structured to evaluate the medical condition of the subject based on the blood CO2 and oxygen saturation or close approximations thereof. |
