oksühemoglobiiniks
Oksühemoglobiiniks is the Estonian term for oxyhemoglobin. Oxyhemoglobin is the bright red, oxygen-rich form of hemoglobin found in red blood cells. Hemoglobin is a protein molecule responsible for transporting oxygen from the lungs to the body's tissues and carbon dioxide from the tissues back to the lungs. When hemoglobin binds with oxygen, it undergoes a structural change, becoming oxyhemoglobin. This binding process is reversible, allowing oxygen to be released where it is needed most. The color of blood changes from a darker red (deoxygenated hemoglobin) to a brighter red (oxyhemoglobin) as it picks up oxygen in the lungs. This color change is a key indicator of oxygen saturation levels. Measuring the ratio of oxyhemoglobin to deoxyhemoglobin is a common method used in pulse oximetry to assess a person's oxygenation status non-invasively. Factors such as blood pH, temperature, and the concentration of 2,3-bisphosphoglycerate can influence the affinity of hemoglobin for oxygen, thereby affecting the formation and dissociation of oxyhemoglobin.
