hapnikusaturatsioon

Hapnikusaturatsioon, often abbreviated as SpO2, refers to the percentage of hemoglobin in the blood that is saturated with oxygen. Hemoglobin is a protein in red blood cells responsible for transporting oxygen from the lungs to the body's tissues. A normal SpO2 level typically falls between 95% and 100%. Levels below 90% are generally considered low and may indicate a medical problem requiring attention.

Measuring hapnikusaturatsioon is commonly done using a pulse oximeter, a non-invasive device that clips onto a fingertip, earlobe, or toe. The device emits light of specific wavelengths and measures how much light is absorbed by the oxygenated and deoxygenated hemoglobin. This allows for a quick and painless assessment of oxygen levels.

Low hapnikusaturatsioon can be caused by various conditions affecting the respiratory or circulatory systems. These include lung diseases such as pneumonia, asthma, or chronic obstructive pulmonary disease (COPD), as well as heart conditions. Other factors like sleep apnea, high altitude, or even certain medications can also influence SpO2 readings.

Monitoring hapnikusaturatsioon is crucial in clinical settings, particularly for patients with respiratory or cardiac issues, during surgery, or in intensive care units. It provides vital information about the body's ability to deliver oxygen to its cells and can alert healthcare professionals to potential life-threatening situations. In some cases, individuals with chronic lung conditions may be advised to monitor their own SpO2 levels at home.
