WebbThe oxygen-hemoglobin dissociation curve shows the relationship between the partial pressure of oxygen (PO2) and the percent saturation of hemoglobin with oxygen. Hemoglobin's cooperative binding behavior allows it to pick up oxygen efficiently in the lungs, where PO2 is high, and release it efficiently in the tissues, where PO2 is low. WebbThe partial pressure of oxygen (pO2) was measured in the sciatic nerve and the cerebral cortex of adult cats before and during direct, local electrical stimulation of these neural tissues, using stimulus parameters capable of inducing neural injury. pO2 was monitored by the polarographic method, employing a platinum microelectrode inserted into …

Webb8 juni 2024 · When the RQ is known, the partial pressure of oxygen in the alveoli can be calculated: alveolar PO 2 = inspired PO 2 −((alveolar PO 2)/RQ) In the lungs, oxygen diffuses out of the alveoli and into the capillaries surrounding the alveoli. Oxygen (about 98 percent) binds reversibly to the respiratory pigment hemoglobin found in red blood cells. WebbThe partial pressure of oxygen in a pulmonary capillary is about 40 mm Hg. ... Peripheral chemoreceptors increase firing with low arterial PO2 but are not sensitive to an increase in arterial PCO2.
