    In this situation there is not enough oxygen in the alveolar gas to fully oxygenate the blood volume passing through, and P a O 2 will be low. Conversely, an increased V/Q ratio tends to be a consequence of impaired perfusion, in which circumstances the blood supply is insufficient to carry the available oxygen, P a O 2 will be normal, but ...

    To perform the test, one set of electrodes are placed on viable tissue (e.g. the chest) as a control and a second set is placed around the tissue in question (e.g. legs or feet). The electrodes may mildly heat the skin to increase blood flow into the area. Oxygen may also be given to the patient to see if that increases oxygen levels in the tissue.

    en.wikipedia.org/wiki/Histotoxic_hypoxia

    Oxygen extraction decreases in parallel with the lower oxygen consumption, with a resulting increase in venous oxygen content and PvO2. Although cyanide stimulates the peripheral respiratory chemoreceptors, increasing the inspired oxygen fraction is not helpful, since there is already an adequate amount of oxygen which the poisoned cells cannot ...
