If you have insurance, find a doctor to order chest x-ray to evaluate pulmonary insufficency. CT-Scan with IV contrast to rule out pulmonary embolism. 2D-echo to evaluate Left ventricle ejection fraction. blood test: proheart, BNP something like that. Either way, your friend need to see a doctor (pulmonology or cardiology).
