O2saturaatio

O2saturaatio, also known as oxygen saturation, refers to the proportion of hemoglobin molecules in the blood that are bound with oxygen. It is an important physiological parameter used to assess a person's respiratory and circulatory efficiency. Normally, oxygen saturation levels in healthy individuals range from 95% to 100%. Values below this range may indicate hypoxemia, a condition characterized by insufficient oxygen in the blood, which can result from various respiratory or cardiovascular disorders.

Oxygen saturation is typically measured using a non-invasive device called a pulse oximeter. This device clips onto a thin part of the patient's body, such as a fingertip or earlobe, and uses light absorption principles to estimate blood oxygen levels. In clinical settings, arterial blood gas analysis can also determine oxygen saturation more precisely.

Monitoring O2saturaatio is crucial in diagnosing and managing conditions like chronic obstructive pulmonary disease (COPD), pneumonia, asthma, and during anesthesia or intensive care treatment. It provides real-time information about the adequacy of oxygen delivery to tissues and helps guide oxygen therapy or ventilation adjustments.

Abnormal oxygen saturation levels require prompt evaluation to identify underlying causes and prevent complications. Factors influencing O2saturaatio include respiratory rate, lung function, cardiac output, anemia, and altitude. Maintaining oxygen saturation within a normal range is vital for overall health and optimal organ function.
