WebAug 1, 2024 · It is important to differentiate between pO2 (mm Hg, the dissolved fraction), oxygen saturation (% of hemoglobin occupied), and O2 content (expressed as a volume percentage). Arterial oxygen content is approximately 20 g/dL, the venous oxygen content is 15 g/dL, and dissolved oxygen contributes 0.1 g/dL in each case (but is continuously ... WebMethods for determining the dissociation curve fall into three main groups: 1. The p O 2 is set by the experimental conditions, and the percentage saturation of haemoglobin is measured. 2. The percentage saturation is predetermined by mixing known proportions of oxygenated and deoxygenated blood, and the p O 2 is measured. 3. honey and troisWebHemoglobin carries 4 oxygens and holds them the tightest when it has 4, in terms of location in the body this is closest to the lungs (where oxygen is needed the least). ...
