Hemoglobin desaturation curve

WebHyperventilation causes acute hypocapnia resulting in cerebral vasoconstriction, hypocalcemia, a shift in the oxygen–hemoglobin dissociation curve, and reduced oxygen delivery. Symptoms include lightheadedness, dizziness, faintness, paresthesias, and altered consciousness. Hypocalcemia with alkalosis may cause seizures and tetany. Web24 nov. 2024 · Specifically, the oxyhemoglobin dissociation curve relates oxygen saturation (SO 2) and partial pressure of oxygen in the blood (PO 2 ), and is determined by what is called “hemoglobin affinity for oxygen”; that is, how readily hemoglobin acquires and releases oxygen molecules into the fluid that surrounds it.
