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.
Signs and symptoms of foodborne botulism include: 1  Difficulty swallowing or speaking. 2  Dry mouth. 3  Facial weakness on both sides of the face.  Blurred or double 1  vision. Drooping eyelids.  Trouble 1  breathing. Nausea, vomiting and abdominal cramps.  Paralysis.
The symptoms of botulism make hospitalization necessary. If diagnosed early, foodborne and wound botulism can be treated with an antitoxin that is maintained by the Centers for Disease Control.The antitoxin reduces the progression of paralysis and may reduce the severity and duration of symptoms.ow soon after exposure do symptoms occur? Generally, symptoms begin 12-36 hours after eating contaminated food, but may occur as early as a few hours and as late as 10 days. The incubation period for intestinal (infant) botulism is unknown, though estimated at 3 to 30 days from the time of exposure.
