Detailed explanation-1: -Hemoglobin saturation of 100 percent means that every heme unit in all of the erythrocytes of the body is bound to oxygen. In a healthy individual with normal hemoglobin levels, hemoglobin saturation generally ranges from 95 percent to 99 percent.
Detailed explanation-2: -This means that a hemoglobin molecule can bind up to four oxygen molecules during transport in the blood. For adults, the normal range of SaO2 is 95 – 100%. A value lower than 90% is considered low oxygen saturation, which requires external oxygen supplementation.
Detailed explanation-3: -The healthy range for hemoglobin is: For men, 13.2 to 16.6 grams per deciliter. For women, 11.6 to 15 grams per deciliter.
Detailed explanation-4: -Approximately 98% of total oxygen transported in the blood is bound to hemoglobin, while only 2% is dissolved directly in plasma.
