Claim:
1. A method for determining whether or not additional medical tests need to be conducted for a diagnosis of a pulmonary arterial hypertension condition in a patient, comprising the steps of: a) measuring end tidal carbon dioxide (EtCO2) of each of a plurality of oral expirations from the patient at rest with a system comprising: b) calculating a composite EtCO2 value for the plurality of oral expirations at rest; c) comparing the composite EtCO2 value to the range of carbon dioxide partial pressure values stored in the memory of the system; d) generating a first signal based upon the comparison in step (c), the first signal indicative of whether or not additional medical tests needs to be conducted for the diagnosis of pulmonary arterial hypertension, wherein a lower range of the composite EtCO2 value is indicative of pulmonary arterial hypertension; and e) transmitting the first signal to the indicator of the system.
