Hi Everyone.....I have yet another question [I'm sorry!] I had an ultrasound done on my heart today, and was just wondering what information doctors gain from this re Pulmonary Hypertension? Also had lung function test where the girl told me that "the exchange of gases" [I presume between my heart and lungs?] was "mild to moderate". Two years ago after heart ultrasound they said "Mild to moderate Pulmonary Hypertension". Does this mean the same thing? The girl at the lung function test also said my airways were obstructed, but this was common in asthma sufferers, particularly as I hadn't taken my morning inhaler [I also have asthma]. I know I need to wait to see my dr on Friday, but does anyone know what any of this means? Thank you all so much, and I;m so sorry to bother you all again.
