PaO 2 or âpartial pressure of oxygenâ measures the amount of free oxygen molecules dissolved in plasma (measured in mmHg or Torr). This is not always the most reliable account of the actual oxygenation state of blood as the vast majority of O 2 is bound to hemoglobin.

Aside from a longer incubation period, wound botulism is similar to foodborne botulism. The incubation period of wound botulism ranges from 4-14 days, with a mean of 10 days.

In many cases, the wound appears benign.
