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.
However, it is not nearly as much as we have seen in dark chocolate. It is hard to quantify how much caffeine is in milk chocolate because each manufacturer has its own recipe, and the percentage of chocolate that comes from the cocoa bean varies widely from manufacturer to manufacturer.
