One important fact to keep in mind is that following a rapid decompression to and above 30,000 feet, the average TUC/EPT will be reduced from 1/3 to 1/2 its original value. This can be caused by a lack of blood from extreme bleeding, or can be caused by other issues, like Carbon Monoxide poisoning, which prevents the cells from absorbing oxygen. The most common hypoxia treatment for lung conditions is to remove any blockages so that the patient may breathe better, either through medication or surgery, and sometimes hook the patient to an oxygen supply to ensure he or she is getting adequate amounts.

The fourth type of hypoxia, histotoxic hypoxia, is most often seen in cases of cyanide poisoning. (2)] Hypoxia is a state of oxygen deficiency in the blood, tissues, and cells sufficient to cause an impairment of body functions. of hypoxia, the symptoms and causes, and the treatment for this condition. Low doses (cyanide <1 mg l -1 = 38 mol l -1, lactate <10 mmol l -1 blood) cause headache, nausea, confusion, drowsiness, tachypnea, and tachycardia. Hemoglobin bonds with carbon monoxide 200 times more readily than it bonds with oxygen.
