WebHowever, there is some evidence that there may not be a direct relationship between oxygen supplementation and lower desaturation rates. For example, Riley et al. 13 found no significant difference in the postoperative low oxyhemoglobin saturation (LSAT) between patients receiving continuous positive airway pressure (CPAP) and the non-CPAP group. WebThe normal oxyhemoglobin dissociation curve (OHDC), shown here by the solid blue line, indicates that when the partial pressure of arterial oxygen (Pa O2) is 40 mm Hg, oxy - gen saturation of hemoglobin (Sa O2) is 75%. At the tissue or capillary level, a Pa O2of 40 mm Hg is normal. At this point, about 25% of the oxygen carried on hemoglobin from grand marais mich campground

"WebMixed venous oxygen saturation (SvO2) is the percentage of oxygen bound to hemoglobin in blood returning to the right side of the heart. This refects the amount of oxygen "left over" after the tissues remove what they need. It is used to help us to recognize when a patient's body is extracting more oxygen than normally.

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.
