NettetThis figure shows that when the blood becomes slightly acidic, with the pH decreasing from the normal value of 7.4 to 7.2, the oxygen-hemoglobin dissociation curve shifts, on average, about 15 per cent to the right. Conversely, an increase in pH from the normal 7.4 to 7.6 shifts the curve a similar amount to the left. The strength with which oxygen binds to hemoglobin is affected by several factors. These factors shift or reshape the oxyhemoglobin dissociation curve. A rightward shift indicates that the hemoglobin under study has a decreased affinity for oxygen. This makes it more difficult for hemoglobin to bind to oxygen (requiring a higher partial pressure of oxygen to achieve the same oxygen saturation), but it makes it easier for the hemoglobin to release oxygen bound to it. The …

NettetWith acidosis, the oxyhemoglobin dissociation curve shifts to the right, which facilitates the unloading of oxygen at the tissues, increasing oxygen delivery. With alkalosis, the oxyhemoglobin dissociation curve shifts to the left, which diminishes unloading of oxygen at the tissues, so oxygen delivery is decreased.
