To the Editor.— The letter of Major Allen B. King appearing inTheJournalJune 26, 1972, on the subject of hypoxia and hypercapnia 1 from bedcovers was of particular interest to me because it suggests the probable pathophysiology underlying a type of headache that I have studied in a number of patients.

Publisher Summary The essential feature of hypoxia is the cessation of oxidative phosphorylation when the mitochondrial PO2 falls below the critical level. The anaerobic pathways, in particular the glycolytic pathway, then come into play. The glycolysis is initiated under hypoxic conditions by the accumulation of adenosine diphosphate (ADP) that acts ...

Many biochemical changes occur during acclimation to altitude. Some appear to be deleterious, but the increase in cytochrome-P 450 and the changes in the endoplasmic reticulum seem to be beneficial. The latter changes could reduce the capillary to oxidase gradient to compensate for the lower capillary oxygen tensions.

The use of extensive monitoring approaches in patients with various forms of hypoxic disease has flourished extensively during the past decade. When coupled to advanced computer technology, the capacity for generation and storage of data has increased enormously. In addition to clinicians and biomedical scientists, the field has attracted engineers and

Microcirculation brings about the convective transport of O2 through the capillary network of the tissue. From the capillaries into the tissue O2 is transported mainly by diffusion. Within the tissue O2 reacts with cytochrome oxidase which is part of the respiratory chain. The respiratory chain is situated in the mitochondria.
