Pulmonary edema (American English), or oedema (British English; both words from the Greek Î¿á¼´Î´Î·Î¼Î±), is fluid accumulation in the air spaces and parenchyma of the lungs. It leads to impaired gas exchange and may cause respiratory failure.
According to Hershey's a 1.55 oz (43 g) milk chocolate bar has 9 mg of caffeine.
Of course, this doesnât mean you should run out and start consuming Hershey bars at an epic rate, because Hershey bars aren't exactly bursting at the seams with actual cocoa, but it's a nice to know that consuming chocolate that is high in cocoa (read: dark), is, in some ways, really good for us.
